i own a long haired guinea pig , it is mostly orangy yellow with black stripes (like a tiger) he also has some white here and there, (i attached an image) he is only 10-11 weeks old but i would like to determine his breed, before asking this question i checked loads of guinea pig breed sites but none of them had my little boys species on.
also, he only has one rossette on his back.
what breed is he?

If your pig is only 10-11 weeks old my guess is that he is a Peruvian. A Peruvian looks like a long haired Abyssinian. Abys have 10 rosettes on their body but their hair is not very long. It gives them a scruffy appearance, but each rosette is in a set pattern.

Peruvians also have those rosettes, but because the hair grows very long the rosettes are not really visible when they're in what we call 'show coat.' Most Peruvians that are purchased as pets or are used in breeding have had their coats trimmed. When showing they are wrapped in individual wraps and kept on all the time so that the pig cannot chew his coat or break it by stepping on it.

Since your pig is young his coat will not have had an opportunity to grow long and will probably stay at the length you have now. He actually has more rosettes than you can really see. When a Peruvian's coat is long the rosettes give it what we call density. The hair on top of his head between his ears is called the 'frontal' and would eventually grow over his face.

His color is called 'broken' meaning it is two or more colors. I'm attaching a couple of pictures for you. One is a young Peruvian whose coat has not grown out. This pig is a little older than yours and that's why the hair is longer. It's still not an adult and will grow more.

The other picture is an Aby. This particular pig belonged to a friend of mine from Australia and this was taken at one of his shows. You can see the clearly defined rosettes and see they are not very long.

In Australia they have pigs that may look identical to American bred pigs but are actually genetically different. However the Peruvians and Abys in Australia are the same genetically as those in the US.

I hope this helps you out.

As is sometimes the case, people in urgent need of information have a higher degree of expectation than those of us as experts are able to give. The experts on this site do their best to give the most accurate and responsible answers possible. We ask that you remember that it is not our intention nor place to criticize the professional advice given by your veterinarian, nor is it appropriate for us to comment on the correctness of a diagnosis made by a licensed physician. Our knowledge is experience based. Although many years of breeding and showing cavies gives me a wealth of experience it cannot change the fact that we as experts are not veterinarians and therefore may occasionally have to reject questions that appear to be asking us to criticize advice given by the licensed professional. Having raised and exhibited cavies for many years I have extensive experience in cavy care and husbandry. I currently have an active breeding program for pedigreed show animals but do not encourage backyard breeding for inexperienced owners. Although I don't encourage breeding for fun I'm always happy to answer any questions from an owner who is in sincere need of help. Pet owners wanting to breed should understand that even experienced breeders have litter losses. The mortality rate is high in cavies. The chance for losing both sow and pups is always present, even with experience. Although this is a site for experts to assist owners, there is no expert in any field who has all the answers. The wisest thing a good expert can know is their limitations. Not having an answer does not diminish one's ability or knowledge. It simply shows that we recognize our limitations and operate within them.


Raised and shown cavies for many years, having aquired my first cavies in the early 1970's as pets. My caviary currently handles 65 + animals in two different breeds and several varieties. Having been in the health care industry as a licensed nurse for 35 years I have hands on experience with care and needs in both humans and cavies. Member of American Rabbit Breeders Association and American Cavy Breeders Association.

Awarded Lifetime Membership in of one of the oldest cavy clubs in the United States, on whose Board I served as Sec/Treas for six years and currently serving as President. Also editor/publisher of the club's quarterly newsletter. We are strong supporters of our youth exhibitors, most of whom are 4H members who are working on cavy projects. Through these projects they become good responsible citizens. We deal with all aspects of showing, breeding, caring for and sharing experiences in the fancy. The cavy fancy is not a new one but in some areas is still relatively unknown. Our goal is to inspire interest in high quality, responsible breeding to improve the species, not just the reproduction of guinea pigs. Our job is to educate owners to help them make the right decisions and choices in the care of their cavies.
