126-531: The first domestic dogs to arrive in Australia came with the First Fleet in 1788 and later convict fleets. (The Australian Dingo is not classified as a domestic dog.) A thriving stray dog population soon grew. Some of the strays, those with stock work potential, apparently found home with the free settler, George Hall. Thomas Hall, a son of George, developed them into working dogs. Robert Kaleski , who wrote

252-465: A bird-of-paradise species heard but not seen, Hewitt relates that his veteran trek guide called out "dog" four times and pointed to fetch Hewitt and his trek client from their explorations behind large boulders and have them realize that ahead and above the guide and camp cook on a rocky outcrop was a dog, in Hewitt's words "not scared, but...genuinely curious...as we were of it, and it certainly felt like

378-516: A subspecies , a subspecies of dog or wolf , or a full species in its own right. The dingo is a medium-sized canine that possesses a lean, hardy body adapted for speed, agility, and stamina. The dingo's three main coat colourations are light ginger or tan, black and tan, or creamy white. The skull is wedge-shaped and appears large in proportion to the body. The dingo is closely related to the New Guinea singing dog : their lineage split early from

504-586: A taxonomic synonym for the dingo. He referred to the mDNA study as one of the guides in forming his decision. The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists, and their classification under the wolf debated. In 2019, a workshop hosted by the IUCN /SSC Canid Specialist Group considered the New Guinea singing dog and the dingo to be feral dogs ( Canis familiaris ), which therefore should not be assessed for

630-431: A black coat with a tan muzzle, chest, belly, legs, and feet and can be found in 12% of dingoes. Solid white can be found in 2% of dingoes and solid black 1%. Only three genes affect coat colour in the dingo compared with nine genes in the domestic dog. The ginger colour is dominant and carries the other three main colours – black, tan, and white. White dingoes breed true, and black and tan dingoes breed true; when these cross,

756-592: A common ancestor from a ghost population of wolves that disappeared at the end of the Late Pleistocene . The dog and the dingo are not separate species. The dingo and the Basenji are basal members of the domestic dog clade. Mitochondrial genome sequences indicate that the dingo falls within the domestic dog clade, and that the New Guinea singing dog is genetically closer to those dingoes that live in southeastern Australia than to those that live in

882-467: A comparison of modern dingoes with these early remains, dingo morphology has not changed over these thousands of years. This suggests that no artificial selection has been applied over this period and that the dingo represents an early form of dog. They have lived, bred, and undergone natural selection in the wild, isolated from other dogs until the arrival of European settlers, resulting in a unique breed. In 2020, an MDNA study of ancient dog remains from

1008-456: A difference existed between camp dingoes and wild dingoes as they had different names among indigenous tribes. The people of the Yarralin, Northern Territory , region frequently call those dingoes that live with them walaku , and those that live in the wilderness ngurakin . They also use the name walaku to refer to both dingoes and dogs. The colonial settlers of New South Wales wrote using

1134-513: A distinct species Canis hallstromi , and Canis lupus dingo when considered a subspecies of the wolf. In 2019, a workshop hosted by the IUCN /SSC Canid Specialist Group considered the New Guinea singing dog and the dingo to be feral dogs Canis familiaris , and therefore should not be assessed for the IUCN Red List . During the Torres expedition to the south coast of New Guinea and

1260-426: A group of canines came within several hundred meters of him. Flannery apparently did not have his camera along or ready, since he reported no pictures taken. In 1996 Robert Bino undertook a field study of these dogs, but was not able to observe any wild New Guinea singing dogs and instead used signs, such as scats, paw prints, urine markings and prey remnants, to make conclusions about their behaviour. No DNA sampling

1386-570: A group of large carnivores that are genetically closely related because their chromosomes number 78; therefore they can potentially interbreed to produce fertile hybrids . In the Australian wild there exist dingoes, feral dogs, and the crossings of these two, which produce dingo–dog hybrids . Most studies looking at the distribution of dingoes focus on the distribution of dingo-dog hybrids, instead. Dingoes occurred throughout mainland Australia before European settlement. They are not found in

1512-626: A haunting and extraordinary sound, which has led to their alternative name of "New Guinea Singing Dog." Flannery published in his book a photo of a black-and-tan dog in the Telefomin District . He wrote that these dogs live with native people in the mountains, and that there were feral populations living in the alpine and sub-alpine grasslands of the Star Mountains and the Wharton Range . Compared with other forms of dog,

1638-532: A heterotypical sequence have also been observed. The bark-howling starts with several barks and then fades into a rising and ebbing howl and is probably (similar to coughing) used to warn the puppies and members of the pack . Additionally, dingoes emit a sort of "wailing" sound, which they mostly use when approaching a watering hole , probably to warn already present dingoes. According to the present state of knowledge, getting Australian dingoes to bark more frequently by putting them in contact with other domestic dogs

1764-777: A light buffy, a dark mark across the jaw separating the light chin-spot from the pale undersurface. Dimensions of Holotype : Head and body approximately 650 mm (26 in); tail exactly 245 mm (9.6 in), less brush; heel to longest toe, less nail, 145 mm (5.7 in); dew-claw from base to ground, 25 mm (0.98 in); ear, length from outer base to tip 75 mm (3.0 in), midwidth 40 mm (1.6 in); longest vibrissa 52 mm (2.0 in); length of head to extremity of sagittal crest 180 mm (7.1 in) (approx.) and bi-zygomatic width 100 mm (3.9 in); rear molar to incisor 90 mm (3.5 in); width across incisors 23 mm (0.91 in); height of upper canine 16 mm (0.63 in). By

1890-646: A native animal study center in Nondugi, and from there to the Taronga Zoo in Sydney , Australia. In 1957, Ellis Troughton examined the two singing dog specimens from the Taronga Zoo and classified them as a distinct species Canis hallstromi in honour of Hallstrom. Troughton described the type specimen as follows: Specimens . – Male holotype, female allotype, in possession of Sir Edward Hallstrom at Taronga Zoological Park, Sydney, for eventual lodgment in

2016-422: A network for their swift transfer around the continent. Based on the recorded distribution time for dogs across Tasmania and cats across Australia once indigenous Australians had acquired them, the dispersal of dingoes from their point of landing until they occupied continental Australia is proposed to have taken only 70 years. The red fox is estimated to have dispersed across the continent in only 60–80 years. At

2142-420: A photo of a black-and-tan dog in Telefomin District . He noted that these dogs lived with local tribal peoples in the mountains, and that feral populations lived in the alpine and sub-alpine grasslands of the Star Mountains and the Wharton Range . The photo was published in his book, Mammals of New Guinea . In 2012, Australian wilderness-adventure guide Tom Hewett took a photo of a tawny, thick-coated dog in

2268-535: A rare meeting for both sides. The guides and cook were also surprised". While the guide had at first approached "quite close", the dog retreated as the party came toward it, though it stayed on the hillside while being photographed for a mutual observation session of about 15 minutes. Hewitt only became fully aware of the importance of his party's sighting and photograph of this dog when he contacted Tom Wendt, New Guinea Singing Dog International (NGSDI)'s founder upon returning home, then regretting that he did not videorecord

2394-486: A similar manner to kangaroos, the difference being that a single dingo hunts using scent rather than sight and the hunt may last several hours. Dingo packs may attack young cattle and buffalo, but never healthy, grown adults. They focus on the sick or injured young. The tactics include harassing a mother with young, panicking a herd to separate the adults from the young, or watching a herd and looking for any unusual behaviour that might then be exploited. One 1992 study in

2520-477: A sound is not known for any other canid; however, a similar sound (with lower frequency) has been described for a dhole at the Moscow Zoo . When they are kept with dogs that bark, New Guinea singing dogs may mimic the other dogs. The New Guinea singing dog possesses an annual seasonality, and if not impregnated will have a second estrus within a few weeks after the end of the first. Sometimes they will have

2646-701: A specialized diet, but they seem to thrive on lean raw meat diets based on poultry , beef , elk , deer , or bison . Natives interviewed in the highlands state that these dogs steal the kills of Papuan eagles . Since 1956, New Guinea singing dogs have been obtained or sighted in the wild chiefly in mountainous terrain around the central segment of the New Guinea Highlands , a major island-extensive east–west running mountain range formation. The 1956 dogs obtained by Papua New Guinea District Officer J.P. Sinclair and his medical assistant Albert Speer (see 'Taxonomic history' section above) were obtained from

2772-555: A split between the New Guinea singing dog lineage from the southeastern dingo lineage 7,800 years ago. The study proposes that two dingo migrations occurred when sea levels were lower and Australia and New Guinea formed one landmass named Sahul that existed until 6,500–8,000 years ago. Whole genome analysis of the dingo indicates there are three sub-populations which exist in Northeast (Tropical), Southeast (Alpine), and West/Central Australia (Desert). Morphological data showing

2898-649: A study of the maternal lineage through the use of mitochondrial DNA (mDNA) as a genetic marker indicates that the dingo and New Guinea singing dog developed at a time when human populations were more isolated from each other. In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: " familiaris Linnaeus, 1758 [domestic dog]" and " dingo Meyer, 1793 [domestic dog]". Wozencraft included hallstromi —the New Guinea singing dog—as

3024-409: A third. Males in captivity often participate in raising the pups, including the regurgitation of food. Female New Guinea singing dogs are protective of their young and will aggressively attack their male counterpart if they suspect he poses a danger to the pups. During the first breeding season following their birth, especially if there is a potential mate present, pups are often aggressively attacked by

3150-476: A tooth-gnashing threat. During estrus , when potential partners are present, same-sex New Guinea singing dogs often fight to the point of severe injury. Furthermore, adults also display a high degree of aggression towards unfamiliar dogs, which would indicate that they are strongly territorial. Their distinctive aggression could not be observed to that extent among Australian dingoes (who live without human contact). Researchers have noted rough play behaviour by

3276-400: A variety of habitats, including the temperate regions of eastern Australia , the alpine moorlands of the eastern highlands , the arid hot deserts of Central Australia , and the tropical forests and wetlands of Northern Australia . The occupation of, and adaption to, these habitats may have been assisted by their relationship with indigenous Australians. A 20-year study of the dingo's diet

3402-420: Is a medium-sized canid with a lean, hardy body that is adapted for speed, agility, and stamina. The head is the widest part of the body, wedge-shaped, and large in proportion to the body. Captive dingoes are longer and heavier than wild dingoes, as they have access to better food and veterinary care. The average wild dingo male weighs 15.8 kg (35 lb) and the female 14.1 kg (31 lb), compared with

3528-443: Is a relay pursuit until the prey is exhausted. A pack of dingoes is three times as likely to bring down a kangaroo than an individual because the killing is done by those following the lead chaser, which has also become exhausted. Two patterns are seen for the final stage of the attack. An adult or juvenile kangaroo is nipped at the hamstrings of the hind legs to slow it before an attack to the throat. A small adult female or juvenile

3654-480: Is an inherited defect. In Queensland, however, the two types (long- and short-tailed) were originally exhibited as two varieties of the one Cattle Dog breed, but by the 1950s, separate classes – Cattle Dog (long-tail) and Cattle Dog (short-tail) – were more usual. During the 1950s administrative decisions taken by the Canine Control Council (Queensland) , and consequent legal proceedings, threatened

3780-450: Is bitten on the neck or back by dingoes running beside it. In one area of Central Australia, dingoes hunt kangaroos by chasing them into a wire fence, where they become temporarily immobilised. The largest male red kangaroos tend to ignore dingoes, even when the dingoes are hunting the younger males and females. A large eastern grey kangaroo successfully fought off an attack by a single dingo that lasted over an hour. Wallabies are hunted in

3906-410: Is characterized by a sharp increase in pitch at the start and very high frequencies at the end. The howling of these dogs can be clearly differentiated from that of Australian dingoes , and differs significantly from that of grey wolves and coyotes . An individual howl lasts an average of 3 seconds, but can last as long as 5 seconds. At the start, the frequency rises and stabilizes for

4032-450: Is flattish, tapering after mid-length and does not curve over the back, but is carried low. When walking, the dingo's rear foot steps in line with the front foot, and these do not possess dewclaws . Dingoes in the wild live 3–5 years with few living past 7–8 years. Some have been recorded living up to 10 years. In captivity, they live for 14–16 years. One dingo has been recorded to live just under 20 years. The wolf-like canids are

4158-550: Is from Vietnam at 4,000 YBP , and in Island Southeast Asia from Timor-Leste at 3,000 YBP. The earliest dingo remains in the Torres Straits date to 2,100 YBP. In New Guinea, the earliest dog remains date to 2,500–2,300 YBP from Caution Bay near Port Moresby , but no ancient New Guinea singing dog remains have been found. The earliest dingo skeletal remains in Australia are estimated at 3,450 YBP from

4284-432: Is generally lightly allocated over the hair of the spine, concentrating on the back of the ears and the surface of the tail over the white tip. The muzzle is always black on young dogs. Generally, all colors have white markings underneath the chin, on the paws, chest and tail tip. About one third also have white markings on the muzzle, face and neck. By 7 years of age, the black muzzle begins to turn grey. All sightings in

4410-399: Is no definitive evidence that either high altitude wild-living dogs were formerly isolated from other New Guinea canids or that the animals that were the founding members of captive populations of New Guinea Singing Dogs were wild-living animals or the progeny of wild-living animals rather than being born and raised as members of village populations of domestic dogs. We conclude that: In 2020,

4536-426: Is not possible. However, German zoologist Alfred Brehm reported a dingo that learned the more "typical" form of barking and how to use it, while its brother did not. Whether dingoes bark or bark-howl less frequently in general is not certain. New Guinea singing dog The New Guinea singing dog or New Guinea Highland dog ( Canis lupus hallstromi ) is an ancient ( basal ) lineage of dog found in

4662-498: Is possible that they are simply feral domestic dogs or New Guinea singing dog hybrids. On 24 August 2012, the second known photograph of a New Guinea singing dog in the wild was taken by Tom Hewitt, Director of Adventure Alternative Borneo, in the Jayawijaya Mountains or Star Mountains of Papua Province, Indonesia, Western New Guinea by a trek party returning from Puncak Mandala , at approximately 4,760 m high

4788-424: Is still capable of living independently. Any free-ranging, unowned dog can be socialised to become an owned dog, as some dingoes do when they join human families. Although the dingo exists in the wild, it associates with humans, but has not been selectively bred similarly to other domesticated animals. Therefore, its status as a domestic animal is not clear. Whether the dingo was a wild or domesticated species

4914-559: Is that dingoes arrived in Australia 8,300 YBP and brought by an unknown human population. In 2024, a study found that the Dingo and New Guinea singing dog show 5.5% genome introgression from the ancestor of the recently extinct Japanese wolf , with Japanese dogs showing 4% genome introgression. This introgression occurred before the ancestor of the Japanese wolf arrived in Japan. In 2017,

5040-486: Is that of their pupils, which open wider and allow in more light than in other dog varieties. The other is that they possess a higher concentration of cells in the tapetum . New Guinea singing dogs have erect, pointed, fur-lined ears. As with other wild dogs, the ears 'perk,' or lay forward, which is suspected to be an important survival feature for the form. The ears can be rotated like a directional receiver to pick up faint sounds. Their tails are bushy, long enough to reach

5166-407: Is well synchronized, and the howls of the group end nearly simultaneously. Spontaneous howling is most common during the morning and evening hours. A trill, with a distinctly "bird-like" character, is emitted during high arousal. It is a high-frequency pulsed signal whose spectral appearance suggests a continuous source that is periodically interrupted, and might last as long as 800 milliseconds. Such

5292-522: The First Fleet arrived in Botany Bay under the command of Australia's first colonial governor, Arthur Phillip , who took ownership of a dingo and in his journal made a brief description with an illustration of the "Dog of New South Wales". In 1793, based on Phillip's brief description and illustration, the "Dog of New South Wales" was classified by Friedrich Meyer as Canis dingo . In 1999,

5418-614: The Fortescue River region observed that cattle defend their calves by circling around the calves or aggressively charging dingoes. In one study of 26 approaches, 24 were by more than one dingo and only four resulted in calves being killed. Dingoes often revisited carcasses. They did not touch fresh cattle carcasses until these were largely skin and bone, and even when these were plentiful, they still preferred to hunt kangaroos. Of 68 chases of sheep, 26 sheep were seriously injured, but only eight were killed. The dingoes could outrun

5544-538: The IUCN Red List . In 2020, the American Society of Mammalogists considered the dingo a synonym of the domestic dog. However, recent DNA sequencing of a 'pure' wild dingo from South Australia suggests that the dingo has a different DNA methylation pattern to the German Shepherd. In 2024, a study found that the Dingo and New Guinea singing dog show 5.5% genome introgression from the ancestor of

5670-444: The New Guinea Highlands , on the island of New Guinea . Once considered to be a separate species in its own right, under the name Canis hallstromi , it is closely related to the Australian dingo . The dog is relatively unusual among canines; it is one of the few to be considered "barkless", and is known for the unusual " yodel "-like style of vocalizing that gives it its name. In 1989, the Australian mammalogist Tim Flannery took

5796-568: The Puncak Mandala region of West Papua , Indonesia . In 2016, a literature review found no definitive evidence that the earliest possible dogs, within captive populations of New Guinea singing dogs, were wild animals; successive generations of puppies were raised as members of village populations, thus being domestic dogs. In 2020, a genetic study found that the New Guinea Highland wild dogs were genetically basal to

5922-514: The Sydney area. The first British colonists to arrive in Australia in 1788 established a settlement at Port Jackson and noted "dingoes" living with indigenous Australians. The name was first recorded in 1789 by Watkin Tench in his Narrative of the Expedition to Botany Bay : The only domestic animal they have is the dog, which in their language is called Dingo, and a good deal resembles

6048-668: The Torres Strait in 1606, small dogs were recorded by Captain Don Diego de Prado y Tovar: We found small dumb dogs that neither bark nor howl, and do not cry out even if beaten with sticks On 26 October 1897, the Lieutenant-Governor of British New Guinea , Sir William MacGregor , was on Mount Scratchley, Central Province , Papua New Guinea. At an elevation of 7,000 ft (2,100 m) he recorded that "animals are rare," but listed "wild dog." MacGregor obtained

6174-928: The Yellow River and Yangtze River basins of southern China showed that most of the ancient dogs fell within haplogroup A1b, as do the Australian dingoes and the pre-colonial dogs of the Pacific, but in low frequency in China today. The specimen from the Tianluoshan archaeological site , Zhejiang province dates to 7,000 YBP (years before present) and is basal to the entire haplogroup A1b lineage. The dogs belonging to this haplogroup were once widely distributed in southern China, then dispersed through Southeast Asia into New Guinea and Oceania, but were replaced in China by dogs of other lineages 2,000 YBP. The oldest reliable date for dog remains found in mainland Southeast Asia

6300-424: The bark of a dingo is short and monosyllabic, and is rarely used. Barking was observed to make up only 5% of vocalisations . Dog barking has always been distinct from wolf barking. Australian dingoes bark mainly in swooshing noises or in a mixture of atonal and tonal sounds. In addition, barking is almost exclusively used for giving warnings.

Its taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as

6678-668: The Australian Museum observed these dogs around villages situated at 8,000 ft (2,400 m) on Mount Giluwe in the Southern Highlands Province . In 1956, Albert Speer and J. P. Sinclair obtained a pair of singing dogs in the Levani Valley that was situated in what is now Hela Province (formerly part of Southern Highlands Province ). The two dogs had been obtained from natives. The dogs were sent to Sir Edward Hallstrom , who had set up

6804-666: The Australian National Kennel Council introduced a "Development Breeding Programme" to perpetuate the breed. The success of the scheme, to which Iris Heale gave active support, is evident in the growing popularity of the breed. The Stumpy was first recognised as a breed in its own right in 1963, when the Australian National Kennel Council issued a breed standard for the Stumpy Tail Cattle Dog. The name

6930-468: The Kalam people (see § Relationship with humans ). In his 1998 book Throwim Way Leg , Tim Flannery states that the dokfuma (which he describes as sub-alpine grassland with the ground being sodden moss, lichens and herbs growing atop a swamp) at 3,200 meters elevation had plenty of New Guinea singing dogs, which could usually be heard at the beginning and end of each day. When alone in his campsite one day,

DNA analysis of scats indicate that these dogs have a genetic relationship with other dogs found in Oceania, including the dingo and the New Guinea singing dog. In 2020, a nuclear genome study indicates that

7434-625: The New Guinea singing dog is described as relatively short-legged and broad-headed. These dogs have an average shoulder height of 31–46 cm (12–18 in) and weigh 9–14 kg (20–31 lb). They do not have rear dewclaws . The limbs and spine of the New Guinea singing dog are very flexible and they can spread their legs sideways to 90°, comparable to the Norwegian Lundehund . They can also rotate their front and hind paws more than domestic dogs, which enables them to climb trees with thick bark or branches that can be reached from

7560-521: The New Guinea singing dog is genetically closer to those dingoes that live in southeastern Australia than to those that live in the northwest. The dingo and New Guinea singing dog lineage can be traced back through the Malay Archipelago to Asia. In 2016, a literature review found that: there is no convincing evidence that New Guinea wild-living dogs and some, or all, pre-colonization New Guinea village dogs were distinct forms. Further, there

7686-459: The New Guinea singing dog. In 2020, the first whole genome sequencing of the dingo and the New Guinea singing dog was undertaken. The study indicates that the ancestral lineage of the dingo/New Guinea singing dog clade arose in southern East Asia , migrated through Island Southeast Asia 9,900  YBP , and reached Australia 8,300  YBP ; however, the human population which brought them remains unknown. The dingo's genome indicates that it

Colour (Ridgway ) of the head a clear tawny brown; the back a darker russet-brown owing to the admixture of blackish-brown hairs, the darker hairs enclosing a yellowish "saddlemark" somewhat more conspicuous in the female. Outer shoulders and hips clear ochraceous-tawny; tail about tawny-olive brindled above with blackish-brown, tip white; four paws whitish. Underparts

8190-424: The captive male 18.9 kg (42 lb) and the female 16.2 kg (36 lb). The average wild dingo male length is 125 cm (49 in) and the female 122 cm (48 in), compared with the captive male 136 cm (54 in) and the female 133 cm (52 in). The average wild dingo male stands at the shoulder height of 59 cm (23 in) and the female 56 cm (22 in), compared with

8316-480: The captive male 56 cm (22 in) and the female 53 cm (21 in). Dingoes rarely carry excess fat and the wild ones display exposed ribs. Dingoes from northern and northwestern Australia are often larger than those found in central and southern Australia. The dingo is similar to the New Guinea singing dog in morphology apart from the dingo's greater height at the withers . The average dingo can reach speeds of up to 60 kilometres per hour. Compared with

8442-478: The close of the last glacial period 11,700 years ago, five ancestral lineages had diversified from each other and were expressed in ancient dog samples found in the Levant (7,000 YBP), Karelia (10,900 YBP), Lake Baikal (7,000 YBP), ancient America (4,000 YBP), and in the New Guinea singing dog (present day). Mitochondrial genome sequences indicates that the dingo falls within the domestic dog clade, and that

They also scavenge on prey dropped from the nesting platforms of sea eagles. Lone dingoes may hunt small rodents and grasshoppers in grass by using their senses of smell and hearing, then pouncing on them with their forepaws. Dingoes and their hybrids co-exist with

This comparison is sustained in the narrow body and very short bushy tail which measures little more than one third of the combined head-and-body length, with the width of

8820-426: The diet on the lower slopes and wombat on the higher slopes. Possums are commonly eaten here when found on the ground. In coastal regions, dingoes patrol the beaches for washed-up fish, seals , penguins , and other birds. Dingoes drink about a litre of water each day in the summer and half a litre in winter. In arid regions during the winter, dingoes may live from the liquid in the bodies of their prey , as long as

8946-491: The diet, except for long-haired rats that form occasional plagues. In the Fortescue River region, the large red kangaroo and common wallaroo dominate the diet, as few smaller mammals are found in this area. On the Nullarbor Plain, rabbits and red kangaroos dominate the diet, and twice as much rabbit is eaten as red kangaroo. In the temperate mountains of eastern Australia, swamp wallaby and red-necked wallaby dominate

9072-415: The dingo and the New Guinea singing dog, and therefore the potential originator of both. In 1999, a study of mitochondrial DNA (mtDNA) indicated that the domestic dog may have originated from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other. In the third edition of Mammal Species of

9198-429: The dingo skulls from Southeastern Australia (Alpine dingoes) being quite distinct from the other ecotypes. And genomic and mitochondrial DNA sequencing demonstrating at least 2 dingo mtDNA haplotypes colonised Australia. In 2020, a genetic study found that the New Guinea Highland wild dogs were genetically basal to the dingo and the New Guinea singing dog, and therefore the potential originator of both. The dingo

9324-594: The dingo, the New Guinea Highland wild dog, and the New Guinea singing dog. Australian mammalogist Tim Flannery in his book the Mammals of New Guinea describes the "New Guinea Wild Dog" as looking similar to the dingo, only smaller. Most of these dogs in New Guinea are domesticated with large numbers being kept by widows and bachelors, with hunters keeping at least two for assisting them with hunting. These dogs do not bark, and their chorused howling makes

9450-517: The dog, the dingo is able to rotate its wrists and can turn doorknobs or raise latches in order to escape confinement. Dingo shoulder joints are unusually flexible, and they can climb fences, cliffs, trees, and rocks. These adaptations help dingoes climbing in difficult terrain, where they prefer high vantage points. A similar adaptation can be found in the Norwegian Lundehund , which was developed on isolated Norwegian islands to hunt in cliff and rocky areas. Wolves do not have this ability. Compared with

9576-413: The domestic dog by its larger palatal width, longer rostrum , shorter skull height, and wider sagittal crest. However, this was rebutted with the figures falling within the wider range of the domestic dog and that each dog breed differs from the others in skull measurements. Based on a comparison with the remains of a dingo found at Fromme's Landing, the dingo's skull and skeleton have not changed over

9702-508: The encounter. Hewitt and Wendt observe that West Papuan locals report that sightings are rare, and that New Guinea singing dogs have not been domesticated by current human inhabitants of their area. In 2016, a literature review found that "there is no definitive evidence that...the founding members of captive populations of New Guinea Singing Dogs were wild-living animals or the progeny of wild-living animals rather than being born and raised as members of village populations of domestic dogs." In

9828-595: The end of the last glacial maximum and the associated rise in sea levels, Tasmania became separated from the Australian mainland 12,000 YBP, and New Guinea 6,500 –8,500 YBP by the inundation of the Sahul Shelf . Fossil remains in Australia date to around 3,500 YBP and no dingo remains have been uncovered in Tasmania, so the dingo is estimated to have arrived in Australia at a time between 3,500 and 12,000 YBP. To reach Australia through Island Southeast Asia even at

9954-419: The examined dogs generally showed a lower threshold of behaviour (e.g., scent rolling ) than other domestic dogs, as well as an earlier developmental onset than other domestic dogs or grey wolves (e.g., hackle biting at two weeks compared to other domestic dogs/grey wolves at 6 weeks) and a quantitative difference (e.g., reduced expression of intraspecific affiliate behaviours). The dogs observed did not show

10080-552: The first whole genome analysis of the dingo and the New Guinea singing dog was undertaken. The study indicates that the ancestors of these two dogs arose in southern East Asia , migrated through Island Southeast Asia 9,900 YBP, and reached Australia 8,300 YBP. The study rejects earlier suggestions that these dogs arrived from southern Asia 4,300 YBP or as part of the Austronesian expansion into Island Southeast Asia, which arrived in New Guinea about 3,600 YBP. The genetic evidence

10206-437: The first specimen and later Charles Walter De Vis wrote a description of it in 1911. De Vis summarised from his description that: ... it is not a "truly a wild dog"; in other words that there was a time when its forebears were not wild. ...But if we decide that this dog is merely feral, of a domestic breed run wild, as dogs are apt to do, how are we to account for its habitat on Mount Scratchley? In 1954, collectors for

10332-472: The first standard for the Cattle Dog breed, called Hall's dogs Halls Heelers . The Halls Heelers were later developed into the two modern breeds, Australian Cattle Dog and Australian Stumpy Tail Cattle Dog. Kaleski also suggested that Thomas Hall imported dogs from England. The Sydney-based Kaleski described only long-tailed cattle dogs in his breed standard, published in 1902. The short, or absent, tail

10458-636: The fossil record of Tasmania, so they apparently arrived in Australia after Tasmania had separated from the mainland due to rising sea levels. The introduction of agriculture reduced dingo distribution, and by the early 1900s, large barrier fences, including the Dingo Fence , excluded them from the sheep-grazing areas. Land clearance, poisoning, and trapping caused the extinction of the dingo and hybrids from most of their former range in southern Queensland, New South Wales, Victoria, and South Australia. Today, they are absent from most of New South Wales, Victoria,

10584-580: The fox dog of England. These animals are equally shy of us, and attached to the natives. One of them is now in the possession of the Governor, and tolerably well reconciled to his new master. Related Dharug words include "ting-ko" meaning "bitch", and "tun-go-wo-re-gal" meaning "large dog". The dingo has different names in different indigenous Australian languages , such as boolomo , dwer-da , joogoong , kal , kurpany , maliki , mirigung , noggum , papa-inura , and wantibirri . Some authors propose that

10710-407: The future of the Stumpy Tail Cattle Dog as an exhibited breed. Iris Heale (1919–2006), Glen Iris kennels, became the only registered Stumpy Tail Cattle Dog breeder. She exercised her monopoly by refusing to sell registered animals. During the 1980 some members of the Australian working dog fancy realised Heale’s death would also be the death of the Stumpy Tail Cattle Dog as an exhibited breed. In 1988

10836-553: The ground; however, their climbing skills do not reach the same level as those of the gray fox , and are closely related to those of a cat. The eyes, which are highly reflective, are triangular (or almond-shaped) and are angled upwards from the inner to outer corners with dark eye rims. Eye color ranges from dark amber to dark brown. Their eyes exhibit a bright green glow when lights are shone on them in low light conditions. There are two features which researchers believe allow New Guinea singing dogs to see more clearly in low light. One

10962-398: The guides in forming his decision. The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists. This classification by Wozencraft is debated among zoologists. The New Guinea singing dog's taxonomic status is debated, with proposals that include treating it within the species concept (range of variation) of the domestic dog Canis familiaris ,

11088-559: The highest peak in the Jayawijaya range and second highest freestanding mountain of Oceania , Australasia , New Guinea and Indonesia (though Hewitt himself seems to erroneously say this peak is in the Star Mountains , which are adjacent to the Jayawijaya range, and also casually calls the region 'West Papua' rather than Indonesia's Papua Province in the Western geopolitical 'half' of the New Guinea landmasses, while his identification of

11214-530: The highland wild dogs from the base of Puncak Jaya , within the Tembagapura district in the Mimika Regency of Papua, Indonesia, were the population from which captive New Guinea singing dogs were derived. The study revealed that the wild dogs show much more genetic diversity than the captive animals, which are severely inbred. This indicates the wild population is healthy. The size and distribution of

11340-435: The late 1950s and mid-1970s, wild dogs believed to be New Guinea singing dogs were shy and avoided contact with humans. It was reported in the mid-1970s that the Kalam in the highlands of Papua caught young New Guinea singing dogs and raised them as hunting aids, but did not breed them. Some of these dogs probably stayed with the Kalam and reproduced. The Eipo tribe kept and bred wild dogs as playmates for their children. Although

11466-408: The levels had been disturbed, and the dingo remains "probably moved to an earlier level." The dating of these early Australian dingo fossils led to the widely held belief that dingoes first arrived in Australia 4,000 YBP and then took 500 years to disperse around the continent. However, the timing of these skeletal remains was based on the dating of the sediments in which they were discovered, and not

11592-537: The lineage that led to today's domestic dogs, and can be traced back through Maritime Southeast Asia to Asia. The oldest remains of dingoes in Australia are around 3,500 years old. A dingo pack usually consists of a mated pair, their offspring from the current year, and sometimes offspring from the previous year. The name "dingo" comes from the Dharug language used by the Indigenous Australians of

11718-419: The lowest sea level of the last glacial maximum, a journey of at least 50 kilometres (31 mi) over open sea between ancient Sunda and Sahul was necessary, so they must have accompanied humans on boats. Whole genome sequencing indicates that, while dogs are a genetically divergent subspecies of the grey wolf, the dog is not a descendant of the extant grey wolf. Rather, these are sister taxa which share

11844-430: The most commonly killed prey. The main tactic is to sight the kangaroo, bail it up, then kill it. Dingoes typically hunt large kangaroos by having lead dingoes chase the quarry toward the paths of their pack mates, which are skilled at cutting corners in chases. The kangaroo becomes exhausted and is then killed. This same tactic is used by wolves, African wild dogs , and hyenas . Another tactic shared with African wild dogs

11970-449: The mothers towards their pups, which often switched over to agonistic behaviour as well as "handling." The mothers did not adequately react to the pups' shouts of pain but rather interpreted it as further "invitation" for "playing." The researchers stated that this behaviour was noted in their subjects only and does not necessarily apply to all singing dogs. New Guinea singing dogs are named for their distinctive and melodious howl, which

12096-709: The name dingo only for camp dogs. It is proposed that in New South Wales the camp dingoes only became wild after the collapse of Aboriginal society. Dogs associated with indigenous people were first recorded by Jan Carstenszoon in the Cape York Peninsula area in 1623. In 1699, Captain William Dampier visited the coast of what is now Western Australia and recorded that "my men saw two or three beasts like hungry wolves, lean like so many skeletons, being nothing but skin and bones". In 1788,

12222-727: The native quoll . They also co-occur in the same territory as the introduced European red fox and feral cat , but little is known about the relationships between these three. Dingoes and their hybrids can drive off foxes from sources of water and occasionally eat feral cats. Dingoes can be killed by feral water buffalo and cattle goring and kicking them, from snake bite, and predation on their pups (and occasionally adults) by wedge-tailed eagles . Like all domestic dogs, dingoes tend towards phonetic communication. However, in contrast to domestic dogs, dingoes howl and whimper more, and bark less. Eight sound classes with 19 sound types have been identified. Compared to most domestic dogs,

12348-874: The neck. They come in various patterns of blue or red. Unlike Australian Cattle Dogs, the standard forbids tan markings, which are considered signs of a mix-breed dog. The ideal temperament of the Stumpy is described in the breed standard as alert and watchful, as well as responsive to its owner and reserved around strangers. They are high energy dogs with high stimulation needs. Stumpies may compete in dog agility trials, obedience , showmanship , flyball , tracking , frisbee and herding events. Herding instincts and trainability can be measured at noncompetitive herding tests. Stumpies exhibiting basic herding instincts and can be trained to compete in herding trials. Dingo Canis familiaris Linnaeus, 1758 Canis familiaris dingo Meyer, 1793 The dingo (either included in

12474-456: The northwest. The dingo and New Guinea singing dog lineage can be traced back from Island Southeast Asia to Mainland Southeast Asia. Gene flow from the genetically divergent Tibetan wolf forms 2% of the dingo's genome, which likely represents ancient admixture in eastern Eurasia. By the close of the last ice age 11,700 years ago, five ancestral dog lineages had diversified from each other, with one of these being represented today by

12600-665: The number of prey is sufficient. In arid Central Australia, weaned pups draw most of their water from their food. There, regurgitation of water by the females for the pups was observed. During lactation, captive females have no higher need of water than usual, since they consume the urine and feces of the pups, thus recycling the water and keeping the den clean. Tracked dingoes in the Strzelecki Desert regularly visited water-points every 3–5 days, with two dingoes surviving 22 days without water during both winter and summer. Dingoes, dingo hybrids, and feral dogs usually attack from

12726-491: The past 3,000 years. Compared to the wolf, the dingo possesses a paedomorphic cranium similar to domestic dogs. However, the dingo has a larger brain size compared to dogs of the same body weight, with the dingo being more comparable with the wolf than dogs are. In this respect, the dingo resembles two similar mesopredators , the dhole and the coyote. The eyes are triangular (or almond-shaped) and are hazel to dark in colour with dark rims. The ears are erect and occur high on

12852-402: The peak is quite clear, including its estimated elevation which is distinctive among New Guinea's peaks). In a valley flanked by waterfalls on both sides among approximately 4 km (13,000 ft) high limestone peaks, replete with such flora and fauna as cycads , grasses and blooms of the highlands, cuscuses , possums , tree kangaroos , unidentified ground-nesting birds in swamp grass, and

12978-403: The potential originator of both. These dogs live wildly in a harsh and remote environment between 3,900–4,170 metres (12,800–13,680 ft) in elevation, which suggests they are a lineage of proto-dog that is related to the dingo and are not feral village dogs. This has led to some researchers to suggest that the taxon Canis dingo is appropriate for the only truly wild-living dog populations –

13104-459: The range's spine. The reported habitat of the New Guinea singing dog consists of mountains and swampy mountain regions of Papua New Guinea at an altitude of 2,500 to 4,700 meters. The main vegetation zones are the mixed forest , beech and mossy forest , sub-alpine coniferous forest and alpine grassland. Based on archaeological , ethnographic , and circumstantial evidence, it can be assumed that New Guinea singing dogs were once distributed over

13230-451: The rear as they pursue their prey. They kill their prey by biting the throat, which damages the trachea and the major blood vessels of the neck. The size of the hunting pack is determined by the type of prey targeted, with large packs formed to help hunt large prey. Large prey can include kangaroos, cattle, water buffalo, and feral horses. Dingoes will assess and target prey based on the prey's ability to inflict damage. Large kangaroos are

13356-566: The recently extinct Japanese wolf , with Japanese dogs showing 4% genome introgression. This introgression occurred before the ancestor of the Japanese wolf arrived in Japan. The dingo is regarded as a feral dog because it descended from domesticated ancestors. The dingo's relationship with indigenous Australians is one of commensalism , in which two organisms live in close association, but do not depend on each other for survival. They both hunt and sleep together. The dingo is, therefore, comfortable enough around humans to associate with them, but

13482-485: The relative proportions of the size of prey mammals varied across regions. In the tropical coast region of northern Australia, agile wallabies, dusky rats, and magpie geese formed 80% of the diet. In Central Australia, the rabbit has become a substitute for native mammals, and during droughts, cattle carcasses provide most of the diet. On the Barkly Tableland , no rabbits occur nor does any native species dominate

13608-465: The rest of the howling, but normally shows abrupt changes in frequency. Modulations can change quickly every 300–500 milliseconds or every second. Five to eight overtones can generally be distinguished in a spectrographic analysis of the howling. New Guinea singing dogs sometimes howl together, which is commonly referred to as chorus howling. During chorus howling, one dog starts and others join in shortly afterward. In most cases, chorus howling

13734-413: The result is a sandy colour. The coat is not oily, nor does it have a dog-like odour. The dingo has a single coat in the tropical north of Australia and a double thick coat in the cold mountains of the south, the undercoat being a wolf-grey colour. Patchy and brindle coat colours can be found in dingoes with no dog ancestry and these colours are less common in dingoes of mixed ancestry. The dingo's tail

13860-500: The same across Australia, apart from more birds being eaten in the north and south-east coastal regions, and more lizards in Central Australia. Some 80% of the diet consisted of 10 species: red kangaroo , swamp wallaby , cattle, dusky rat , magpie goose , common brushtail possum , long-haired rat , agile wallaby , European rabbit , and common wombat . Of the mammals eaten, 20% could be regarded as large. However,

13986-401: The same year, the New Guinea Highland Wild Dog Foundation announced to the media that it and the University of Papua had located and photographed a group of 15 of what it referred to as "highland wild dogs". DNA analysis of scats indicate that these dogs have a genetic relationship with other dogs found in Oceania, including the dingo and the New Guinea singing dog. According to reports from

14112-540: The same-sex parent. Reports from local sources in Papua New Guinea from the 1970s and the mid-1990s indicate that New Guinea singing dogs—like wild dogs found in New Guinea, whether they were pure New Guinea singing dogs or hybrids—fed on small to middle-sized marsupials , rodents , birds , and fruits . Robert Bino stated that their prey consisted of cuscuses , wallabies , and possibly dwarf cassowaries . New Guinea singing dogs in captivity do not require

14238-744: The sheep and the sheep were defenceless. However, the dingoes in general appeared not to be motivated to kill sheep, and in many cases just loped alongside the sheep before veering off to chase another sheep. For those that did kill and consume sheep, a large quantity of kangaroo was still in their diet, indicating once again a preference for kangaroo. Lone dingoes can run down a rabbit, but are more successful by targeting kits near rabbit warrens. Dingoes take nestling birds, in addition to birds that are moulting and therefore cannot fly. Predators often use highly intelligent hunting techniques. Dingoes on Fraser Island have been observed using waves to entrap, tire, and help drown an adult swamp wallaby and an echidna. In

14364-414: The skull of the dog, the dingo possesses a longer muzzle , longer carnassial teeth, longer and more slender canine teeth , larger auditory bullae , a flatter cranium with a larger sagittal crest , and larger nuchal lines . In 2014, a study was conducted on pre-20th century dingo specimens that are unlikely to have been influenced by later hybridisation. The dingo skull was found to differ relative to

14490-409: The skull. The dingo's three main coat colours are described as being light ginger (or tan), black and tan, and creamy white. The ginger colour ranges from a deep rust to a pale cream and can be found in 74% of dingoes. Often, small white markings are seen on the tip of the tail, the feet, and the chest, but with no large white patches. Some do not exhibit white tips. The black and tan dingoes possess

14616-510: The southeastern third of South Australia, and the southwestern tip of Western Australia. They are sparse in the eastern half of Western Australia and the adjoining areas of the Northern Territory and South Australia. They are regarded as common across the remainder of the continent. The dingo could be considered an ecotype or an ecospecies that has adapted to Australia's unique environment. The dingo's present distribution covers

14742-595: The specimens themselves. In 2018, the oldest skeletal bones from the Madura Caves were directly carbon dated between 3,348 and 3,081 YBP, providing firm evidence of the earliest dingo and that dingoes arrived later than had previously been proposed. The next-most reliable timing is based on desiccated flesh dated 2,200 YBP from Thylacine Hole, 110 km west of Eucla on the Nullarbor Plain, southeastern Western Australia. When dingoes first arrived, they would have been taken up by indigenous Australians, who then provided

14868-409: The typical canid play bow; however, Imke Voth found this behaviour during examinations in the 1980s. Several behaviours unique to New Guinea singing dogs have been noted: Additionally, New Guinea singing dogs have an unusual form of auto-erotic stimulation , which includes a strong tendency to target the genitals for both playful and aggressive bites, a cheek-rub that may be a marking behaviour and

14994-404: The whole of New Guinea and later restricted to the upper mountains. Since there have been no verified sightings of these dogs in Papua New Guinea since the 1970s until an August 2012 photograph in the wild, these dogs are now apparently rare. There were reports of New Guinea singing dogs in the Star Mountains until 1976, and in the mid-1970s reports of capture and training, but not breeding by

15120-521: The wild population is not known. Mitochondrial DNA indicates that the highland wild dogs possess the A29 haplotype, rather than the A79 haplotype which is found in the New Guinea singing dog. The A29 haplotype is found in dingoes, some New Guinea singing dogs, and some Asian, Arctic, and village dogs. A phylogenetic tree shows the highland wild dogs to be basal to the dingo and New Guinea singing dog, and therefore

15246-600: The wild were of single dogs or pairs, therefore it can be inferred that wild New Guinea singing dogs do not form permanent packs. Tim Flannery's short 1989 report on dogs in the mountains of Papua New Guinea described them as "extraordinarily shy" and "almost preternaturally canny." According to Robert Bino (1996), these dogs only use their resting places under roots and ledges in New Guinea sporadically. Bino conjectured that these dogs are highly mobile and forage alone and concluded that they therefore might use several hiding places in their home range. During research observations,

15372-508: Was changed to Australian Stumpy Tail Cattle Dog in 2001 and in 2003 the breed was accepted by the Fédération Cynologique Internationale . The ANKC standard asks for "a well proportioned working dog, rather square in profile with a hard-bitten, rugged appearance". They have small pricked ears and a naturally short tail under 10 centimetres (3.9 in). The coat is short and dense with a small ruff around

15498-668: Was conducted across Australia by the federal and state governments. These examined a total of 13,000 stomach contents and fecal samples. For the fecal samples, determining the matching tracks of foxes and feral cats was possible without including these samples in the study, but in distinguishing between the tracks left by dingoes and those of dingo hybrids or feral dogs was impossible. The study found that these canines prey on 177 species represented by 72.3% mammals (71 species), 18.8% birds (53 species), 3.3% vegetation (seeds), 1.8% reptiles (23 species), and 3.8% insects, fish, crabs, and frogs (28 species). The relative proportions of prey are much

15624-540: Was conducted. There have been reports from local residents that wild dogs have been seen or heard in higher reaches of the mountains. In a 2007 report, a more recent sighting was the fleeting glimpse of a dog at Lake Tawa in the Kaijende Highlands . Local assistants assured the researchers that the dogs at Lake Tawa were wild-living dogs, since there were no villages near that location. It needs to be made clear, however, that "wild-living" does not necessarily mean that canines observed by natives are New Guinea singing dogs. It

15750-516: Was not clarified from Meyer's original description, which translated from the German language reads: It is not known if it is the only dog species in New South Wales, and if it can also still be found in the wild state; however, so far it appears to have lost little of its wild condition; moreover, no divergent varieties have been discovered. The earliest known dingo remains, found in Western Australia, date to 3,450 years ago. Based on

15876-478: Was once a domestic dog which commenced a process of feralisation since its arrival 8,300 years ago, with the new environment leading to changes in those genomic regions which regulate metabolism, neurodevelopment, and reproduction. A 2016 genetic study shows that the lineage of those dingoes found today in the northwestern part of the Australian continent split from the lineage of the New Guinea singing dog and southeastern dingo 8,300 years ago, followed by
