Recognized ACBA breeds:
Abyssinain and Abyssinian Satin: The Abyssinains have a short coat of stand-up rosettes and ridges. Show quality cavies will not have smooth spots and will have a minimum of eight clearly defined rosettes. The Satin's coat shines and appears to shimmer in the light.
American and American Satin: The American's coat is short, flat and smooth. The Satin has a brilliant sheen to it's coat.
Coronet: Coronets have a long, soft coat. They are characterized by one single rosette or crest (coronet) on the top of their head. In order to be shown the rosette must be centered. The hair on their body is longer than the hair on their face.
Peruvian and Peruvian Satin: The Peruvain has a very long, dense coat if allowed to grow out completely. They have a sweep which grows over the face and grows as long as the rest of the coat. The Satin's coat has a brilliant shine to it.
Silkie and Silkie Satin: The Silkie (sometimes referred to as a "Sheltie") has a long thick coat which grows in a backward fashion and does not part down the middle like other long-haired breeds. The hair at the face is shorter than the hair on the back. The Satin is characterized by the sparkle and shine of the coat.
Teddy and Teddy Satin: A Teddy (sometimes called a "Rex" which is a totally different breed found more in Europe) has a very short, dense coat that appears very kinky and is wiry to the feel. The very short hairs stand up over the entire body and return back to their normal appearance after disturbed. The Satin has a distinctive glimmer.
Texel: The Texel has a long coat of ringlets or kinky curls and appears very full and round. It's curl is even on the belly where the coat is shorter.
White Crested: They have a coat similar to that of an American, short and flat. What seperates them is the distinctive "white" rosette or crest on the top of their head. They cannot have any white on any other part of their body.
**Satins: It is important to note that a satin coat is not just a shiny coat but a brilliant shine that glimmers and sparkles, which is very distinctive from a cavy with a shiny coat. If "Satin" is not listed with the breed it is not recognized by the ACBA. Some breeds such as Coronets may occasionally be found in a "Satin" but "Coronet Satin" is not a recognized breed.
Other Popular Cavies and New Breeds:
Himalayan: The Himalayan is identified by it's unique coloring. They are born all white with red eyes and will remain a very bright white until adulthood when their ears, nose and feet turn a grey or chocolate color. (The coloring is also influenced by climate: lighter = warmer and darker = cooler). Himalayans however are not a "breed". Short-haired Himalayans can be shown in the "American" category. Himalayan Texels have become very poplular and are shown in the "Texel" category.
Skinny: The Skinny is a hairless breed and smaller than other cavies. A true Skinny is not totally hairless, they have a patch of wiry, very short hair on their nose and feet. Some have scattered wiry hairs on their body and are called "Werewolves". They come in a variety of colors. Their skin is soft and warm to the touch.
Baldwin: The Baldwin, another hairless breed, has hair at birth but it quickly falls out. They will then be totally hairless. They are closer in size to other cavy breeds and larger than the Skinny. Their skin has a rougher texture than the Skinny.
Guinea pigs come in a huge variety of colors and patterns. One to three colors can be present for showing purposes. Those colors are White and/or One from the Reds: red, orange, buff, cream. And/or One from the Blacks: black, chocolate, lilac, beige. There are also "Dilute" color variations of the Red and Black series.
Agouti Agoutis appear to have all-over highlighted tips. Each hair root is from the "Black" family and the tip is from the "Red" family. The belly is the same color as the tips.
Solid Agoutis have a coat that is ticked or tipped all over the body, including the belly.
Agoutis can be patched as well. For instance: A golden agouti & white has patches of hair where the roots are dark (black series) with gold/red tips (red series) and patches of solid white.
Brindle Brindles have strands or small sections of black series and red series hairs throughout their coats. (Not ticked/tipped.)
Brokens have two or three colors of hair in various combinations which does not fit into any other category.
Black & Tan They are black except for the belly and the circles around the eyes.
Dalmatians appear to have "spots" of color on a white back and white sides. (Their white is a genetically different white than any other. It is possible for a white guinea pig to actually have two different "whites" in it's coat)
Dutch is a pattern similar to a "Dutch" rabbit's. Bands of color with bands of white in between.
Himalayan All white guinea pig which develops color a color pattern similar to that of a Siamese cat over time. Their nose, ears and feet will have a color from the Black series. (Their "white" is actually a unique color.)
Martins The siver & black version of the Black & Tan
Roans Each individual white hair on the body alternates evenly with another color, on their back and sides. Their "white" is a unique color. They are genetically the same as a Dalmatian and sometimes both patterns can be found on one cavy. (Because Roans and Dalmatians are genetically the same they should never be bred together, more often than not it will result in birth defects.) Red & White = Strawberry Roan & Black & White = Blue Roan
Self is an all over, one-colored cavy. (Never breed two "white" guinea pigs of unknown background. Birth defects could result.)
Tortiseshells have distinct patches of red and black. It is desirable to have very straight dividing lines to create an even "Checkerboard" pattern.
Tortiseshell & White or TSW's have even patches of red, black and white with nice dividing lines.
