80-481: The Rottweiler ( / ˈ r ɒ t w aɪ l ər / , UK also /- v aɪ l ər / , German: [ˈʁɔtvaɪ̯lɐ] ) is a breed of domestic dog , regarded as medium-to-large or large. The dogs were known in German as Rottweiler Metzgerhund , meaning Rottweil butchers ' dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market. This continued until
160-456: A breed standard which is a written description of the ideal specimen of the breed. Other uses of the term breed when referring to dogs include pure breeds , cross-breeds , mixed breeds and natural breeds . Prior to the standardization of dog breeds, there were many different types of dogs that were defined by their own, unique functions. Many different terms were used to describe dogs, such as breed, strain, type, kind, and variety. By

400-450: A 0.46 kg (1.0 lb) teacup poodle to a 90 kg (200 lb) giant mastiff . The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire order of carnivores. These breeds possess distinct traits related to morphology, which include body size, skull shape, tail phenotype, fur type and colour. The difference in size has been attributed to
480-575: A 2010 study ( Afghan Hound , Akita , Alaskan Malamute , American Eskimo , Basenji , Canaan dog , Chow Chow , Dingo , New Guinea singing dog , Saluki , Samoyed , Shar-Pei , Siberian Husky ), plus another three: the Eurasier , Finnish Spitz and Shiba Inu . The study referred to these 16 as basal breeds, as opposed to ancient breeds, as they exhibited genetic divergence but not all of them were historically considered to be "ancient breeds". The 2012 study found that modern breeds only emerged in

According to the FCI Standard a Rottweiler is always "black with clearly defined markings of a rich tan on the cheeks, muzzle, throat, chest and legs, as well as over both eyes and under the base of the tail" The American Kennel Club calls for mahogany or rust-colored markings that do not take up more than ten percent of
640-737: A known foundation stock may still not be recognized by some clubs as breeds. For instance, the feist is a hunting dog raised in the Southern United States for hunting small game. Feists have a consistent set of characteristics that reliably differentiate them from other dog types and breeds. However, the United Kennel Club recognizes one breed of feist, the Treeing Feist , while the American Kennel Club does not recognize any feist breed. A dog
720-471: A mix of two breeds and is not the result of intentional breeding . In the United States, the term mixed-breed is a favored synonym over mongrel among individuals who wish to avoid negative connotations associated with the latter term. The implication that such dogs must be a mix of defined breeds may stem from an inverted understanding of the origins of dog breeds. Purebred dogs have been, for

There is a natural change in forcefulness when herding sheep. When working cattle, it may use its body and shoulders and for this reason should be used on horned stock with caution. The Rottweiler, when working cattle, searches out the dominant animal and challenges it. Upon proving its control over that animal it settles back and tends to its work. Some growers have found that Rottweilers are especially suited to move stubborn stock that simply ignore Border Collies , Kelpies , and others. Rottweilers use their bodies to physically force
1040-566: A result, today dogs are the most abundant carnivore species and are dispersed around the world. The most striking example of this dispersal is that of the numerous modern breeds of European lineage during the Victorian era . A genetic study identified 51 regions of the dog genome which were associated with phenotype variation among breeds in the 57 traits studied, which included body, cranial, dental, and long bone shape and size. There were three quantitative trait loci that explained most of
1120-488: A select set of ancestors who had the same characteristics. Dogs of a specific breed breed true , producing young that are very similar to their parents. An individual dog is identified as a member of a breed through proof of ancestry, using genetic analysis or written records of ancestry. Without such proof, identification of a specific breed is not reliable. Such records, called stud books , may be maintained by individuals, clubs, or other organizations. Kennel clubs provide
1200-728: A sled dog is 20–25 kg (44–55 lb) based on thermo-regulation, and the ancient sled dogs were between 16–25 kg (35–55 lb). The same standard has been found in the remains of sled dogs from this region 2,000 years ago and in the modern Siberian Husky breed standard. Other dogs were larger at 30 kg (66 lb) and appear to be dogs that had been crossed with wolves and used for polar-bear hunting. Between 3,000 and 4,000 years ago greyhound -types of dogs were depicted on pottery and paintings in Egypt and Western Asia. Mastiff -type dogs were kept for guarding and hunting, and short-legged dogs were also bred. Most modern dog breeds are

"Designer Dog" became a fad in the late 20th century. Dog crossbreeds are combinations of lineages of the domestic dog ; they are distinguished from canid hybrids , which are interspecific crosses between Canis species (wolves, coyotes, jackals, etc.). Notable canid hybrids include

An American study reviewing over a million cases presented to 27 veterinary teaching hospitals in North America found the Rottweiler to be prediposed to canine hip dysplasia , with 10.53% of dogs having the condition compared to 3.52% overall. This same study found the Rottweiler to also have the second highest prevalence of cranial cruciate ligament deficiency (CCLD) with 8.29% of dogs having
1520-740: Is a term formerly, but no longer, used for a particular group of dog breeds by the American Kennel Club. These breeds were referred to as "ancient", as opposed to modern, breeds because historically it was believed their origins dated back more than 500 years. In 2004, a study looked at the microsatellites of 414 purebred dogs representing 85 breeds. The study found that dog breeds were so genetically distinct that 99% of individual dogs could be correctly assigned to their breed based on their genotype , indicating that breeding barriers (purebred breeding) have led to distinct genetic units. The study identified 9 breeds that could be represented on
1600-486: Is a trotting dog. In movement the back remains firm and relatively stable. Movement harmonious, steady full of energy and unrestricted, with good stride. However, "sluggish action while trotting" is considered a "Severe Fault". According to the American Kennel Council the traditional gait of a Rottweiler is a trot. Therefore, the Rottweiler is a trotter. Trotting in this breed is by no means a fault and

Walker states that "The Rottweiler is very territorial", meaning that the owner will have to regularly work with the dog to control its territorial aggressiveness. According to the American Kennel Club, Rottweilers have a natural gathering style with a strong desire to control. They generally show a loose eye and have a great amount of force while working well off

Historically, crosses between dogs of different types were more well accepted at a time when modern purebred breeds (based on the eugenics principles) did not yet exist. Some crossbred dogs, created by breeding two purebred dogs of different breeds, may have the advantage of heterosis , or crossbreed vigor. This advantage can be progressively diluted when two crossbreeds are bred in

2560-589: The "Rottweil butcher's dog". The butchers bred this type of dog purely for performance and usefulness. In due course, a first rate watch and driving dog evolved which could also be used as a draught dog. The buildup to World War I saw a great demand for police dogs , which led to a revival of interest in the Rottweiler. During the First and Second World Wars , Rottweilers saw service in various roles, including as messenger, ambulance, draught, and guard dogs.

Dog breed A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size and shape, tail phenotype , fur type, etc, but are only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within
3040-891: The Rottweiler's toes. Technically a "medium / large" breed, according to the FCI standard the Rottweiler stands 61–69 cm (24–27 in) at the withers for males, 56–63 cm (22–25 in) for females, and the weight must be between 50 and 60 kg (110 and 132 lbs) for males and 35 and 48 kg (77 and 105 lbs) for females. Weight must be relative to height. One study published in 2008 found that male Rottweilers have higher confidence, sharpness, and defense and play drives than females. A 2008 study surveying breed club members found that while Rottweilers were average in aggressiveness (bites or bite attempts) towards owners and other dogs, it indicated they tend to be more aggressive than average toward strangers. This aggression appears correlated with watchdog and territorial instincts. In

In the Victorian era , directed human selection developed the modern dog breeds, which resulted in a vast range of phenotypes. Most breeds were derived from small numbers of founders within the last 200 years, and since then dogs have undergone rapid phenotypic change and were formed into today's modern breeds due to artificial selection imposed by humans. These breeds can vary in size and weight from

In 2010, a study looked at 48,000 single nucleotide polymorphisms that gave a genome -wide coverage of 912 dogs representing 85 breeds. The study found distinct genetic clusters within modern dogs that largely corresponded to phenotype or function. These included spitz-breeds, toy dogs, spaniels, Mastiff-like breeds, small terriers, retrievers, herding dogs, scent-hounds, and sight-hounds. There were 17 breeds that conflicted with phenotype or function and these were thought to be

As in a 2004 study that found 9 'ancient breeds' to be genetically divergent, the study found 13 breeds that were genetically divergent from the modern breeds: the Basenji , Saluki , Afghan hound , Samoyed , Canaan dog , New Guinea singing dog , dingo , Chow Chow , Chinese Shar Pei , Akita , Alaskan malamute , Siberian husky and American Eskimo dog . The study found that there were three well-supported groups that were highly divergent and distinct from modern domestic dogs. The earliest books in
5680-455: The rules for conformation dog shows and trials and accreditation of judges. They often serve as registries , which are lists of adult purebred dogs and lists of litters of puppies born to purebred parents. A dog breed is represented by a sufficient number of individuals to stably transfer its specific characteristics over generations. Dogs of same breed have similar characteristics of appearance and behavior, primarily because they come from
5760-408: The second highest in the study. One study found the Rottweiler to be prediposed to gastric dilatation volvulus . However another study did not find a predisposition. The Rottweiler is often portrayed in media as being dangerous or aggressive. Some films and television shows, such as Lethal Weapon 3 , the 1998 film Half Baked , and the hit HBO show Entourage , have portrayed Rottweilers in
5840-440: The stock. They make much use of their ability to intimidate. The Rottweiler often carries the head on an even plane with the back, or carries the head up but with the neck and shoulders lowered. Some females lower the entire front end slightly when using their eyes. Males also do this when working far off the stock in an open field. This is rarely seen in males when working in confined spaces such as stock yards. The Rottweiler has
5920-423: The stubborn animal to do its bidding if necessary. When working with sheep, the Rottweiler shows a gathering/fetching style and reams directions easily. It drives sheep with ease. If worked on the same stock for any length of time, the Rottweiler tends to develop a bond with the stock and will become quite affectionate with them as long as they do as it directs. The Rottweiler is also exceptionally suited for and
6000-475: The upper incisors closely overlapping the lower incisors. The zygomatic arches should be pronounced (but not exaggerated). Upper and lower jaw strong and broad. Strong, complete dentition (42 teeth) with scissor bite, the upper incisors overlapping the lower incisors. The eyes should be of medium size, almond-shaped and dark brown in colour. The eyelids are close fitting and should not droop. The ears are medium-sized, pendant, triangular, wide apart, and set high on
6080-608: The upper line; while paying attention, when excited or while moving it can be carried upward in a light curve; at ease it may be hanging. While positioned along the leg, the tail reaches approximately to the hocks or is a bit longer. Historically the tail was traditionally docked at the first or second joint. However, docking is now banned in most countries and this is reflected in the FCI Country of Origin Breed Standard. Although once "preferred" in early Standards, in 2018
6160-490: The upper thigh and the lower thigh, and the lower thigh and metatarsal. The upper thigh is moderately long, broad and strongly muscled. The lower thigh is long, strongly and broadly muscled, sinewy. The hocks are sturdy, well-angulated, not steep. The hind feet are slightly longer than the front feet. Toes are strong, arched, as tight as the front feet. According to the FCI Standard: The Rottweiler
6240-546: The use and description of various dog types is The Master of Game (circa 1406) by Edward of York , a treatise that describes dogs and their work, such as the alaunt , greyhound, pack scent hounds, spaniel , and mastiff , used by the privileged and wealthy for hunting purposes. The Master of Game is a combination of the earlier Art of Venery and the French hunting treatise Livre de Chasse by Gaston Phoebus (circa 1387). The Book of Saint Albans , published in 1486,
6320-478: The very recent product of cross-breeding other basal breeds. Most basal breeds have hybridized with other lineages in the past. If those other lineages were other basal breeds then a basal genetic signature remains. The combination of introgression and past population bottlenecks suggested that basal breeds have little or no genetic connections to their ancestral populations and that their genetic distinctiveness does not signify ancient heritage. They are distinctive from
6400-474: Was officially recognised by the American Kennel Club . In 1936, Rottweilers were exhibited in Britain at Crufts . In 1966, a separate register was opened for the breed. In fact, in the mid-1990s, the popularity of the Rottweiler reached an all-time high, as it was the most registered dog by the American Kennel Club. In 2017, the American Kennel Club ranked the Rottweiler as the eighth-most popular purebred dog in
