List of guinea pig breeds

A prize-winning lilac-and-white Silkie

There are many Spanish conquest of the Inca Empire in 1532, selective breeding by indigenous South American people resulted in many landrace varieties of domestic guinea pigs, which form the basis for some of the modern, formal breeds.[1] Early Andean varieties were primarily kept as agricultural stock for food, and efforts at improving the guinea pig as a food source continue to the modern era.

With the export of guinea pigs to Europe in the 15th century, the goal in breeding shifted to focus on the development of appealing pets. To this end, various

While the roan/Dalmatian factor is consistently visible in heterozygous carriers that do not have other factors producing white hair, the pattern can be masked by extreme dilution (resulting in full white colouration) or extreme white spotting.

The roan/Dalmatian factor, sometimes called the "lethal white gene" or simply "lethal gene", is an incomplete dominant. It is lethal when homozygous, resulting in full white pups with varying combinations of deafness, blindness, loss of smell, and deformities. Some homozygous pups may survive for some time, while others die soon after birth if not euthanised. Most roan/Dalmatian breeders breed roan/Dalmatian solely to non-carriers to avoid the 50% risk of homozygous pups for breeding carrier to carrier.

A roan cavy has white hairs evenly intermixed on their body, while a Dalmatian cavy has a white body with coloured spots. The latter is named after the spotted Dalmatian dog, and is not actually from Dalmatia. The head and the rump are mostly coloured in both varieties. They are caused by the same gene, and whether a cavy appears roan or Dalmatian is defined by modifier factors. Many cavies have an intermediate roan/Dalmatian pattern, and these varieties are challenging to successfully breed in show quality.

Roan and Dalmatian

A tortoiseshell ("tortie" for short) cavy has patches of red and black. An ideal show tortoiseshell cavy has regular, well-defined patches of each colour on each side, and appears to have lengthwise "seams" on its back and belly. Diluted tortoiseshells are called broken colours, and diluted tortoiseshell-and-whites tricolours. They follow the same pattern ideal.


A tan cavy is an otherwise solid black, with red ticking around the muzzle, around the eyes, in spots above the eyes, under the neck and the belly, and sparsely on the lower sides. Otter and fox cavies have yellow and white ticking, respectively. Different shades are named after the black series shade, for instance black otter, lilac-and-tan, and grey fox.

Tan, otter, fox

A magpie cavy is a particular form of brindle, with black for the black series and white for the red series. It can easily be confused with Roan, although in magpie the white hairs can appear anywhere on the cavy.


A Himalayan cavy is born solid white, the points slowly gaining colour after a few weeks. These guinea pigs are thought to originate in southeast Asia, similar to the Himalayan, Siamese and related cat breeds.

A Himalayan cavy has a white body with coloured points (face, ears, feet). It is an acromelanic, i.e. temperature-responding colouration, and its degree of darkness depends on how cool or warm the cavy is kept in. Show Himalayans should have black or dark brown points with ruby, i.e. dark red, eyes. The darkest areas should be the face, paws, and the feet.


A Dutch cavy has a specific white pattern: a blaze on the face, a wide white band around the neck, chest, and the belly, including the front paws, and white tips on the hind feet. The pattern is essentially the same as the Dutch pattern in rabbits, and was named after it.


A brindle cavy has intermixed hairs of both black and red series colours throughout their coats, with no ticking. An ideal show brindle appears uniformly coloured, with both series appearing evenly all over.

A solid agouti or argente cavy is completely ticked. Its variations are referred to like normal agoutis and argentes, i.e. a solid argente with beige and golden would be called a golden solid argente, and so forth.

Solid agouti and solid argente

An agouti or argente cavy has a solid coloured belly and is otherwise fully ticked. Variations with black or chocolate (with dark eyes) are called agouti, and variations with beige, grey, and lilac (with red eyes) are called argente. Two common variations are the golden agouti, with black and red, and the silver agouti, with black and white.

Ticked cavies have black series hairs with red seried ticking, i.e. each individual hair has stripes of both a black and a red series colour. In case a ticked cavy also has the tortoiseshell pattern, the red series patches are uniformly coloured while the black series patch.

A white cavy is completely pure white, with either clear red (pink-eyed white, PEW) or black eyes (dark-eyed white, DEW).


A red cavy is reddish brown, with black eyes and black skin. The coat should be as deeply red as possible.


A chocolate cavy is deep brown, with black eyes and black skin. The colour often fades into a greyish brown or even steel grey, especially in long-coated cavies. However, there are lines that do not usually fade.


A black cavy is black, with black eyes and black skin. The coat should be as dark as possible.


A self cavy is uniformly of one colour, without any ticking or patterning. Self colours are divided into three groups: the black series (with black and its dilutions), the red series (with red and its dilutions), and the whites. When discussing ticked and patterned colourations, the self colour terms are used to denote specific shades.

A black and a pink eyed white cavy. Both are Satin Short Hairs.


In case of broken-coloured cavies, i.e. any cavies with other than separately recognised combinations of colours, the colour is described in order of magnitude, i.e. a mostly lilac cavy with some cream and a speck of white would be called lilac-cream-and-white, while a mostly white cavy with a patch of red-black ticking would be white-and-golden-agouti.

Cavies of various breeds have several colourations and patterns. For short-coated cavies, most colours constitute breed variations bred and shown separately from other colours. All colourations should be true throughout the coat, with the roots and tips being of same shade.


The breed was developed from spontaneously mutated pups born to American Crested parents of a single breeder.

The Baldwin is a nearly hairless breed. Baldwins are born with a full coat, which sheds out with age until only a little hair remains on the feet.


The breed was developed from a hairless laboratory strain crossed with Teddies and other haired breeds.

The Skinny is a mostly hairless breed, with some short rough hair on the face and the feet. Pups are born nearly hairless.

Skinny Pig


Few varieties of hairless Guinea pig exist, the most prevalent breeds being the Skinny pig and the Baldwin. They are two separate breeds, with different genetic factors rendering them hairless. Hairless cavies in general need warmer accommodation and more energy-rich food to compensate for the loss of body heat. They are also susceptible to draught, drying of the skin, and skin infections without careful husbandry.

Hairless breeds

A Teddy has a short, rough, very dense and springy coat that stands up all over the body. The hair typically grows to a moderate length and generally makes this breed resemble a soft toy more than any other. Another unique feature of the Teddies in the USA is the relatively long hair coating their bellies. The Teddy has a kinky, springy coat that is famous for its soft, cuddly quality, often compared to an old teddy bear. They come in Plush Coat and Harsh Coat, the plush coated animals having a softer coat, and the harsh coated with a coarser texture to the hair.

Abyssinians are deemed by many as good pets for experienced owners of exotic animals but their excitable nature makes them not necessarily a good choice for first time cavy owners.

Abyssinians tend to be excitable by nature, and often are allowed to strut on the judging table to show off rosette placement. Some exhibitors may groom their Abysinnians before a show with a toothbrush or similar object, but it is undesirable to bathe this particular breed as it softens the ideally harsh texture of the coat. However, any faking is to result in disqualification from the competition.

Abyssinians are to be shown (in the ARBA standard) in six color classifications; Self (to include Beige, Black, Chocolate, Cream, Lilac, Red, Red-Eyed Orange, and White), Agouti (to include Dilute Agouti, Golden Agouti, and Silver Agouti), Brindle, Roan, Any Other Solid (to include Dilute Solid, Golden Solid, and Silver Solid), and Marked (to include Broken Color, Tortoise Shell, Dalmatian, Dutch, Himalayan, and Tortoise Shell & White). All colors and patterns are accepted, although some colorations are much more common than others.

Between the rosettes of the Abyssinian's hair are the ridges, worth 25 points by ARBA standard. The ridges between two rosettes should ideally stand rigidly straight, without breaking down onto either side even if pressed down lightly with the palm of a hand. There should be a collar ridge, back ridge, rump ridge, and ridges between every saddle, hip, and rump rosette. ARBA faults for flatness of coat, crooked ridges, a short coat, and soft texture. Other hair disqualifications include a coat over 1.5 inches in length and a satin sheen (not to be confused by the natural luster of some varieties). Required head furnishings (5 points by ARBA standard) include a well formed mustache and an erect mane running down the head.

The Abyssinian breed is known for their 'rosettes', which are cowlicks growing from the coat. The rosettes are worth 25 points by ARBA standard. The hair is coarse and harsh, shaped in precise rosettes over the body. There are 10 rosettes on a show cavy; four saddle, two shoulder, two hip, and two rump rosettes. Some judging bodies, such as the ANCC, consider shoulder rosettes optional but desired in show Abyssinians. The rosettes are to be round with pinpoint centers, and are to be faulted for guttering (elongated rosettes), double rosettes, and unevenly placement. Any Abyssinian showing an interfering extra rosette or missing any required rosettes are to be disqualified from the competition. Double rosettes do not count toward final rosette count.

The derivation of the breed's name is unknown, but does not connote an origin in the geographical region of Abyssinia (present day Ethiopia).

The Sheba is a long haired, rosetted cavy, characterized by mutton chop whiskers, with frontal, presented to one side of the face, and in a naturally tousled appearance. They have been recognized as a cavy breed in Australia. Their breed standard was developed by Wynne Eecen of Sydney New South Wales, in the 1970s, and was published in her book Pigs Isn't Pigs.[9] Often referred to as the "Bad Hair Day" Cavy.

Sheba (Sheba Mini Yak)

It was initially described as a dominant rex Peruvian, but later was named Lunkarya, a variation of the last name of breed's creator Lundqvist.

The Lunkarya, sometimes Lunk for short, is a new breed group developed first in Sweden, and mainly seen in the Nordic countries. It has a long, rough, curly coat that should be very dense and full. The group has three breed variations: the Lunkarya Peruvian (with a prominent forelock), the Lunkarya Sheltie (with the hair flowing back over the body), and the Lunkarya Coronet (with a crest on the forehead).


The Merino resembles the Coronet, but has curly hair.

Merino (English Merino)

The Coronet resembles the Silkie with its smooth coat growing backwards over its body, but it has a crest on its forehead. Like with the short-coated crested breeds, this crest should be symmetrical with a tight centre and no sticking hairs.

The Peruvian resembles the Silkie with its smooth coat, but has a prominent "forelock" resulting from a portion of its coat on the head and the neck growing forward on the body.

A Texel has a long coat flowing back over the body like with a Silkie's, with the difference that the coat is curly. Originating from England, the Texel was officially recognized as a breed by the ACBA in 1998.[8] According to the US standard, the curls should ideally be tightly wound corkscrew curls and should cover the entire body, including the stomach. A lengthwise part in the coat is acceptable. However, the original standard from England, where the breed originated, states, that the Texel is the rexoid equivalent of the Sheltie, and therefor, the Texel should be combed out the same way you would comb out a sheltie, though still show a rexoid appearance.

Texel Guinea Pig


A Silkie has long, smooth coat that flows back over the body. A Silkie must never have any rosettes or any hair growing in a direction towards its face. Its coat should not have a part. When viewed from above, a Silkie and its coat forms a teardrop shape. The coat is generally accepted to have a somewhat longer sweep of hair in the rear.


All breeds, excluding the Texel, White Crested, and Coronet, have a satin version. For example, the Teddy has the Teddy Satin, the Silkie has the Silkie Satin, and the American has the American Satin.

The satin is a variety with a characteristic satin-like, almost glassy sheen to its coat like its name suggests. The genetic factor for satin coat is recessive and found in all types of coat, long, rough, curly and short. Satin coat is linked to Osteodystrophy (OD), an incurable and potentially painful metabolic disease of the bones. OD symptoms begin showing at around 12 to 18 months, including wobbly gait, problems with eating, and with sows, parturition complications.[5] Due to animal welfare concerns, some registries such as the Swedish and Finnish guinea pig associations, refuse to register satin cavies or cavies with a satin parent.[6][7]

Satin Breeds

The White Crested is similar to the American, but they have one white rosette on the forehead. The breed standards and ideals are nearly identical, with the exception that a White Crested cavy's crest should be completely of a color different from the rest of the animal. Most usually the crest is white, as necessitated by the ACBA standard. No other white hair should be present in the animal. By this standard, White Cresteds are not bred in colourations that have white anywhere on the body, such as Dutch, roan, and Dalmatian.

White Crested

The most common cavy breed, the American cavy is a recognized breed by ARBA. They have a smooth, sleek, shiny coat that comes in many colors, most commonly black. The breed is known for their large, round eyes, roman nose, floppy ears, and calm disposition. They are good pets because of their sweet and gentle personalities.

All cavy breeds have some shared general standards: the head profile should be rounded, with large eyes and large, smooth ears. The body should be strong and of compact build. Coat colour should in all variations be clearly defined and thorough from root to tip. These standards are best met by long established, commonly bred breeds, as their breeders have had enough time and animals to effectively breed for these qualities. The coat colour ideal of good definition and thoroughness is rarely met by other than the smooth-coated breeds, which have had well established, separate breeding lines for different colours.

Though there are many breeds of guinea pig, only a few breeds are commonly found on the show table as pets. Most guinea pigs found as pets were either found undesirable by breeders or were bred to be pleasant pets regardless of how well they meet the breed standard of perfection. The English/American Short-haired, the Abyssinian (rough-coated), the Peruvian (long-coated), and the Sheltie (a.k.a. Silkie, long-coated) breeds are those most frequently seen as pets, and the former three are the core breeds in the history of the competitive showing of guinea pigs. In addition to their standard form, nearly all breeds come in a Satin variant. Satins, due to their hollow hair shafts, possess coats of a special gloss and shine. However, there is growing evidence that the genes responsible for the satin coat also can cause severe bone problems, including osteodystrophy and Paget's disease.[4] Showing satin variations is prohibited by some cavy breeders' associations because of animal welfare reasons.

and New Zealand (Combined Cavy Clubs New Zealand). Each club publishes its own Standard of Perfection and determines which breeds are eligible for showing. New breeds continue to emerge in the 21st century. [3]
