75-653: The Giant Schnauzer is a breed of dog developed in the 17th century in Germany . It is the largest of the three breeds of Schnauzer —the other two breeds being the Standard Schnauzer and the Miniature Schnauzer . Originally bred to assist on farms by driving livestock to market and guarding the farmer's property, the breed eventually moved into the city, where it worked guarding breweries , butchers' shops , stockyards and factories. It
150-456: 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

375-432: A "scissor bite"; oval and dark colored eyes; and v-shaped, natural forward-folding ears (when cropped , the ears point straight upward and come to a sharp point). Their tails are naturally thin and short, and may be docked (where permitted). They will also have very straight, rigid front legs, and feet that are short and round (so-called "cat feet") with thick, black pads. Docking of tails and cropping of ears has become
450-450: 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
525-575: 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
600-769: A Kennel Club survey were lymphoma and liver cancer , followed by heart attacks and heart failure . 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
675-553: A commanding figure when aroused". Giant Schnauzers have been described as trustworthy with children. They are very intelligent, and can become bored easily. They are also very energetic and highly spirited, which, when coupled with boredom, can lead to unwanted and destructive behavior. They are easily trained, and deeply loyal to their owner. They are known to become highly imprinted to their owners. Some breeders believe that pepper and salt colored Giant Schnauzers are more docile than their black-furred counterparts. A 2024 UK study found
750-476: A controversial practice, especially for non-working dogs, and is now illegal or restricted in a number of countries worldwide, including the UK and Australia. Schnauzers have a specific groom cut that is standard among the schnauzer breeds. Schnauzers require regular grooming, either by stripping, or by clipping. Stripping removes the loose, dead coat; it may be done by hand, called finger stripping, or plucking, or with
825-565: A different personality, being more laid back, obedient, friendly, and less aggressive to other dogs. Miniature Schnauzers can compete in dog agility trials, obedience , showmanship , flyball , and tracking . Schnauzers have a high prey drive, which means they may chase other small animals and hence should not be off leash when not in a fenced area. Stanley Coren ranked the Miniature Schnauzer 12th out of 140 breeds in his book The Intelligence of Dogs (2006). Coren grouped

Another sport that the dog excels in is that of nosework . Due to its alert nature, the dog is also used in police work. The first Giant Schnauzers emerged from Swabia in the German state of Bavaria , and Württemberg in the 17th century. These original Giant Schnauzers were considered
975-548: A good territorial instinct, but more inclined toward barking than biting. They are often aloof with strangers until the owners of the home welcome the guest, upon which they are typically very friendly to them. While the Miniature Schnauzer is included in the Terrier Group in North America (due to rat-catching background), it does not have common ancestry with Terriers from Great Britain, and compared to them has

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

The head is 1 ⁄ 2 the length of the dog's back, when the back is measured from the withers to the base of the tail. The cheeks are flat, but well muscled. The coat is dense, wiry, and weather resistant. The fur on
1200-803: A life expectancy of 12.1 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds . Giant Schnauzers require regular grooming. Their beard can collect drool and food particles, making frequent cleanings essential. If being shown, their coat needs to be stripped every two to four weeks. If they are simply a companion animal, the coat can be clipped instead. Some Giant Schnauzers have an allergy to shampoo . Hip and elbow dysplasia are common. Giant Schnauzers are also prone to eye problems such as keratoconjunctivitis sicca , glaucoma , cataracts , multifocal retinal dysplasia , and generalized progressive retinal atrophy . They are also prone to skin diseases, such as seasonal flank alopecia , vitiligo , and follicular cysts. Cancer of
1275-471: 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

Miniature Schnauzer The Miniature Schnauzer is a breed of small dog of the Schnauzer type that originated in Germany in the mid-to-late 19th century. Miniature Schnauzers may have been developed from the smallest specimens of
1425-566: 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
1500-499: A rough-coated version of the German Pinscher breeds, and their hair was thought to help them withstand the harsh German winters and bites from vermin. The origins of the breed are unclear, but sources speculate it originated through some combination of black Great Danes , German Shepherds , Rottweilers , Dobermanns , Boxers , Bouvier des Flandres , Thuringian Shepherds , and the Standard Schnauzer . The Giant Schnauzer
1575-488: 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

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

When kept as pets, Miniature Schnauzers are often groomed differently (usually via clipping) from show dogs (often using stripping). Regular grooming of a Miniature Schnauzer is recommended approximately every six weeks. Clipping, using a mechanical clippers (or shaver), produces a soft, silky, skin-close trim. Whether stripped or clipped,
1800-407: A study indicated that some breed-temperaments, such as anxiety or fear, may be linked to gene mutations. Other temperaments may be due to the legacies of 'ancient' ancestry. Groups of owners that have dogs of the same breed and have an interest in dog breeding can form national Kennel clubs . Kennel Clubs maintain breed standards , record pedigrees in a breed registry (or studbook), and issue
1875-475: Is a global organisation with 98 members and contract partners (one member per country) that recognize 356 purebreds. A dog crossbreed is the result of mating two different breeds. "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
1950-740: 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

It is a global canine organization with member and contract partners (one member per country) that conduct international conformation shows, working/hunting/herding trials, and various other events. The results are submitted to FCI for processing, approval and international recognition. Each of the member and contract partners issue and maintain their own pedigrees and respective breed standards, and train their own judges. FCI ensures that each member mutually recognizes
2250-505: Is one of four color varieties of the Miniature Schnauzer currently recognized by the Fédération Cynologique Internationale . However, they are not accepted for conformation showing by the American Kennel Club and Canadian Kennel Club . The controversy rests on the disputed origins of the white variation, namely whether it was contained within the genes of the originally recognized breed, or whether it

The AKC breed standard calls for males to stand from 65 to 70 centimetres (25.5 to 27.5 in) at the withers , and for females to stand from 60 to 65 centimetres (23.5 to 25.5 in). Giant Schnauzers are square in shape, and should resemble
3375-437: The Giant Schnauzer's face forms a distinct "beard" and eyebrows. Its stride is long and crisp. Giant Schnauzers are usually a quiet breed. Due to its breeding, the Giant Schnauzer is inherently suspicious of strangers and can be very territorial. Once introduced, it is usually accepting of novel people or situations. It has the potential to be aggressive, but Giant Schnauzers are usually reserved – they are "amiable in repose, and

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
