33-621: They belong to the Bichon family group, which includes the Bichon Frisé , Bolognese, Maltese , Löwchen , Havanese and Coton de Tuléar . The precise ancestry of the Bolognese is unknown. Bolognese dogs may be seen in tapestry work produced by Flemish craftsmen dating as far back as the 17th century. The Venetian painter Titian painted the Duke Federico Gonzaga with his Bolognese. The breed

66-421: A blond coat and, therefore, produce offspring looking unlike their parents. Starting in 2007, genetic analysis has become available to the public. The companies claim their DNA -based diagnostic test can genetically determine the breed composition of mixed-breed dogs. These tests are still limited in scope because only a small number of the hundreds of dog breeds have been validated against the tests, and because

99-651: A common foundational breed, making them difficult to separate genetically. For example, Labrador Retrievers , Flat-coated Retrievers , Chesapeake Bay Retrievers , and Newfoundland dogs share a common ancestry with the St. John's water dog – a now-extinct naturally occurring dog landrace from the island of Newfoundland. The theory of hybrid vigor suggests that as a group, dogs of varied ancestry will be generally healthier than their purebred counterparts. In purebred dogs, intentionally breeding dogs of very similar appearance over several generations produces animals that carry many of

132-616: A desired physical trait. The genetic health of hybrids tends to be higher. Healthy traits have been lost in many purebred dog lines because many breeders of showdogs are more interested in conformation – the physical attributes of the dogs in relation to the breed standard – than in the health and working temperament for which the dog was originally bred. Populations are vulnerable when the dogs bred are closely related. Inbreeding among purebreds has exposed various genetic health problems not always readily apparent in less uniform populations. Mixed-breed dogs are more genetically diverse due to

165-439: A diminutive of Old French biche ('female dog', cognate with English bitch ), from Old English bicce , and related to other Germanic words with the same meaning, including Old Norse bikkja , and German Betze . Some speculate the origin of bichon to be the result of the apheresis , or shortening, of the word barbichon ('small poodle'), a derivative of barbiche ('shaggy dog'); however, this

198-491: A mixed-breed dog. North Americans generally prefer the term mix or mixed-breed . Mutt is also commonly used in the United States and Canada . Some American registries and dog clubs that accept mixed-breed dogs use the term All-American to describe mixed-breed dogs. There are also names for mixed-breeds based on geography, behavior, or food. In Hawaii, mixes are referred to as poi dogs, although they are not related to

231-544: A predisposition to the condition in the Bichon Frise, with 9% of cases belonging to the breed despite being 2% of the control population. A study in the UK found the Bichon Frise to be predisposed to gall bladder disease (excluding gall bladder mucocele ). The Bichon Frise was found to be 9.26 times more likely to acquire a non-mucocele gall bladder disease than other dogs. Mongrel A mongrel , mutt , or mixed-breed dog

264-593: Is prekoplotski avlijaner ( over-the-fence yard-dweller ). In Russia , a colloquial term дворняга (yard-dweller) is used most commonly. In the Philippines , mixed-breed street dogs are often called askal , a Tagalog -derived contraction of asong kalye (”street dog"), while in Singapore, they are known as Singapore Specials. In Puerto Rico , they are known as satos ; in Venezuela they are called yusos or cacris ,

297-515: Is vira-lata ( trash-can tipper ) because of homeless dogs who knock over trash cans to reach discarded food. In Newfoundland , a smaller mixed-breed dog is known as a cracky , hence the colloquial expression "saucy as a cracky" for someone with a sharp tongue. Guessing a mixed-breed's ancestry can be difficult even for knowledgeable dog observers, because mixed-breeds have much more genetic variation than purebreds. For example, two black mixed-breed dogs might each have recessive genes that produce

330-524: Is a dog that does not belong to one officially recognized breed , including those that result from intentional breeding . Although the term mixed-breed dog is sometimes preferred, many mongrels have no known purebred ancestors. Crossbreed dogs, and " designer dogs ", while also a mix of breeds , differ from mongrels in being intentionally bred. At other times, the word mongrel has been applied to informally purpose-bred dogs such as curs , which were created at least in part from mongrels, especially if

363-527: Is also seen in paintings by Goya , Gosse and Watteau . Other notable owners of the breed include Catherine the Great of Russia (1729–1796), Madame de Pompadour (1721–1764) and Empress Maria Theresa of Austria . The breed was brought into England in 1990 by Liz Stannard and is first shown during that year in the breed registry . In 2001 the breed was able to be shown at all shows with their own classes. They were at Crufts , an annual international dog show, for

396-451: Is because current accepted breeding practices within the pedigreed dog community result in a reduction in genetic diversity, and can result in physical characteristics that lead to health issues. Studies have shown that crossbreed dogs have a number of desirable reproductive traits. Scott and Fuller found that crossbreed dogs were superior mothers compared to purebred mothers, producing more milk and giving better care. These advantages led to

429-470: Is known as a feist . Slang terms are also common. Heinz 57 , Heinz, or Heinz Hound is often used for dogs of uncertain ancestry, in a playful reference to the "57 Varieties" slogan of the H. J. Heinz Company . In some countries, such as Australia, bitsa (or bitzer ) is sometimes used, meaning "bits o' this, bits o' that". In Brazil and the Dominican Republic , the name for mixed-breed dogs

462-662: Is likely impossible, since the word bichon (attested 1588) is older than barbichon (attested 1694). While the English name for the breed, Bichon Frise , is derived from the French bichon à poil frisé meaning 'curly haired small dog'. The dogs found early success in Spain and it is generally believed that Spanish seamen introduced the early breed to Tenerife in the Canary Islands . Their association with European nobility began in

495-616: The 13th century, entering the royal courts of Spain, Italy and France. In the 14th century, Italian sailors rediscovered the dogs on their voyages and are credited with returning them to continental Europe. The Bichon à Poil Frisé was recognised by the Société Centrale Canine in 1933. It was definitively accepted by the Fédération Cynologique Internationale in October 1959. Some of the dogs were brought to

528-520: The United States in 1955 and to the United Kingdom in 1973. The Bichon Frisé is a small dog, standing 23–30 cm (9–12 in) at the withers and weighing approximately 5 kg (11 lb), the weight varying in proportion to the height. The skull is rather flat, but may appear rounded; the muzzle tapers only slightly, and constitutes two-fifths of the length of the head. The nose is black,

561-426: The United States, the term mixed-breed is a favored synonym over mongrel among people 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 the most part, artificially created from random-bred populations by human selective breeding with

594-426: The breed is not officially recognized. Although mongrels are viewed as of less commercial value than intentionally bred dogs, they are thought to be less susceptible to genetic health problems associated with inbreeding (based on the theory of heterosis ), and have enthusiasts and defenders who prefer them to intentionally bred dogs. Estimates place the prevalence of mongrels at 150 million animals worldwide. In

627-458: The breed with a sample size of 32, compared to an average of 12.7 for purebreeds and 12 for crossbreeds . Bichon Fris%C3%A9 The Bichon Frisé or Bichon à Poil Frisé is a Franco-Belgian breed of small toy dog of bichon type . It was recognised by the Société Centrale Canine in 1933 and by the Fédération Cynologique Internationale in 1959. The French word bichon comes from Middle French bichon ('small dog'),

660-509: The extinct Hawaiian Poi Dog . In the Bahamas and the Turks and Caicos Islands , the common term is potcake dogs (referring to the table scraps they are fed). In South Africa, the tongue-in-cheek expression pavement special is sometimes used as a description for a mixed-breed dog. In Trinidad and Tobago , these mixed dogs are referred to as pot hounds ( pothong ). In Serbia , a similar expression

693-537: The eyes dark and round. The coat is loosely curled in spirals or corkscrews, with a thick soft undercoat. It is always pure white; only in dogs under a year old may it be slightly tinged with beige, this extending over no more than 10% of the area of the body. The head and legs are proportionate in size to the body. A 2024 UK study found a life expectancy of 12.5 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds . An American study looking at immune-mediated hemolytic anemia found

726-403: The first time in 2002. The distinctive single coat (i.e., no undercoat ) falls in loose open ringlets/flocks all over the body, with shorter hair on the face. The hair's texture is woolly, as opposed to silky, and is never trimmed or clipped unless kept as pets. The hair sheds very little, but requires regular combing to prevent matting. A 2024 UK study found a life expectancy of 14.9 years for

759-429: The lack of genetic diversity. If the dog breed is popular, and the line continues, over hundreds of years diversity increases due to mutations and occasional out-breeding. This is why some of the very old breeds are more stable. One issue is when certain traits found in the breed standard are associated with genetic disorders. The artificial selective force favors the duplication of the genetic disorder because it comes with

792-446: The latter being a contraction of the words callejero criollo (literally, street creole, as street dogs are usually mongrels); and in Chile and Bolivia , they are called quiltros . In Costa Rica , it is common to hear the word zaguate , a term originating from a Nahuatl term, zahuatl , that refers to the disease called scabies . In the rural southern United States, a small hunting dog

825-508: The low risk category". Data from Denmark also suggest that mixed breeds have greater longevity on average compared to purebreds. A British study showed similar results, but a few breeds (notably Jack Russell Terriers , Miniature Poodles and Whippets ) lived longer than mixed breeds. In one study, the effect of breed on longevity in the pet dog was analyzed using mortality data from 23,535 pet dogs. The data were obtained from North American veterinary teaching hospitals. The median age at death

858-432: The more haphazard nature of their parents' mating. The offspring of such matings might be less likely to express certain genetic disorders because there might be a decreased chance that both parents carry the same detrimental recessive alleles, but some deleterious recessives occur across many seemingly unrelated breeds, and therefore merely mixing breeds is no guarantee of genetic health. When two poor specimens are bred,

891-523: The offspring could inherit the worst traits of both parents. This is commonly seen in dogs that came from puppy mills . Several studies have shown that mixed-breed dogs have a health advantage over purebred dogs. A German study finds that "mongrels require less veterinary treatment". Studies in Sweden have found that "Mongrel dogs are less prone to many diseases than the average purebred dog" and, when referring to death rates, that "mongrels were consistently in

924-479: The product of artificial selection – intentionally created by humans, whereas the term mongrel specifically refers to dogs that develop by natural selection , without the planned intervention of humans. The words cur , tyke , mutt , and mongrel are used, sometimes in a derogatory manner. There are also regional terms for mixed-breed dogs. In the United Kingdom , mongrel is the unique technical word for

957-418: The purpose of enhancing desired physical, behavioral, or temperamental characteristics. Dogs that are not purebred are not necessarily a mix of such defined breeds. Therefore, among some experts and fans of such dogs, mongrel is still the preferred term. Dog crossbreeds , sometimes called designer dogs , also are not members of a single recognized breed. Unlike mixed-breeds, crossbreed dogs are often

990-429: The same alleles , some of which are detrimental. If the founding population for the breed was small, then the genetic diversity of that particular breed may be small for quite some time. When humans select certain dogs for new breeds, they artificially isolate that group of genes and cause more copies of that gene to be made than might have otherwise occurred in nature. The population is initially more fragile because of

1023-474: The same breed in different geographical areas may have different genetic profiles. The tests do not test for breed purity, but for genetic sequences that are common to certain breeds. With a mixed-breed dog, the test is not proof of purebred ancestry, but rather an indication that those dogs share common ancestry with certain purebreds. The American Kennel Club does not recognize the use of DNA tests to determine breed. Many newer dog breeds can be traced back to

1056-436: Was determined for purebred and mixed-breed dogs of different body weights. Within each body weight category, the median age at death was lower for purebred dogs compared with mixed-breed dogs. The median age at death was "8.5 years for all mixed breed dogs, and 6.7 years for all pure breed dogs" in the study. In 2013, a study found that mixed breeds live on average 1.2 years longer than purebreds, and that increasing body weight

1089-490: Was negatively correlated with longevity (i.e. the heavier the dog, the shorter its lifespan). Another study published in 2019 confirmed this 1.2 year difference in lifespan for mixed-breed dogs, and further demonstrated negative impacts of recent inbreeding and benefits of occasional outcrossing for lifespan in individual dogs. Studies that have been done in the area of health show that mixed-breeds on average are both healthier and longer-lived than their purebred relations. This
