Question
What would a growth under the right eye be caused by

Answer
Pea Eye
Pea Eye  
That's a rather vague description of what you're talking about but I think I may have an idea of what you are called 'a growth'.  Guinea pigs occasionally develop a condition known as pea eye, also sometimes called fatty eye.  

It's actually a fatty deposit inside the lower lid in the conjunctival tissues. It's most commonly seen in pigs with a very round, short nose much like a rabbit. I've posted a picture for you of a common case of pea eye.  It is harmless and has no effect whatsoever on the health of the pig. It's just a cosmetic thing.

Guinea pigs are not actually meant to have a short round nose. The wild guinea pigs have rather long noses but because we humans seem to feel the need to change animals into what we define as more attractive we have created issues that are unique to animals who've been altered by selective breeding for traits that the breeders find more desirable.

Dogs are one of the classic victims of this type of breeding. We've bred German Sheperd Dogs to have an over angulated rear and they no longer have the functionality that is still present in the dogs bred in Germany. We wanted Collies to have a long skinny nose.

Bulldogs are one of the most tragically overbred victims of human desire. They've been bred to have such large broad chests that they no longer are able to breed naturally and must be artificially inseminated. The babies must be born by C Section because the necks of the females are so thick they can't reach down and pull out their own puppies.

Anytime humans begin to alter the normal and natural build of any animal there is a price to pay. With guinea pigs we wanted those short stubby cute noses. We got them, but along with that we got pea eye. For a breeder/exhibitor it's a serious issue. It's passed on to their babies and a pig with pea eye is immediately disqualified from competition in showing.

I hope this is what you are seeing in your pig and not something like a tumor. Tumors are rare in guinea pigs but pea eye is unfortunately too common. If this picture does not show what you are seeing please try to take a picture of your pig and send it so I can get a better idea of what the issue is  I hope this has helped you. I'm sure you can appreciate how difficult it is to diagnose something that I have not seen, but have only a description.

Expertise

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.

Experience

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.

Organizations
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.
