What to do if my guinea pig has worms coming from its bottom?

Thanks for reaching out about Bear. Don't think it is a worm. Could be a vaginal plug. She should be taken back to the store or seen by a veterinarian to look at it. Does she seem uncomfortable or straining? Good luck.

Thanks for reaching out about Teddy and including photos. This could be a sebaceous cyst or abscess. For now, wash the lesions with a mild soap, such as Johnson Baby Shampoo or Dawn dishsoap. If the lesion continue to grow or appears to be bothering Teddy, a veterinary visit is recommended. Good luck.

Guinea pigs can get intestinal parasites but really it is not that common. They can also get fleas but again, not that common. You have to be very careful what medications you use on them. There are not guinea pig specific medications so it is easy to use the wrong thing and it is easy to overdose them. It is best to not use anything unless you are seeing a problem. Some signs that he may have worms: * weight loss * diarrhea * lose of appetite * bloating Some signs he may have fleas: * scratching * hariloss * bald patches * red skin I suggest you just monitor him for any of the above signs and if you see anything abnormal then take him to your vet for an exam so you can give the appropriate medication. Best wishes.

This can be caused by parasites, dietary indiscretion or poor diet. Submit a stool sample to your veterinarian to diagnose intestinal parasites. Treat if indicated. Discontinue feeding any fruits or vegetables for now. Feed only timothy hay and a small amount of pellets daily. Once the stool is normal, you can gradually offer tiny bits of vegetables. Limit fruit though to prevent diarrhea or obesity.

These signs, quite severe in guinea pigs) could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like fecal analysis) may be needed.

If you're having trouble affording veterinary care this site may help give you some ideas to make it more affordable for you, or to find a free or low cost clinic: http://www.humanesociety.org/animals/resources/tips/trouble_affording_veterinary_care.html -- Some clinics and shelters will also have angel funds that provide for the cost of a basic exam and treatment at no cost to you, so asking around your local area may help. Ideally you'd get the piggies a vet visit along with a deworming depending on the type of worms they have. However if you absolutely can't care for them, afford dewormer, or they continue to worsen, then surrendering to a local shelter may be best.

It is hard to tell from the photo but the swelling may just be his testicles they can retract them, so sometimes you won't see them. If there are 2 swellings then it will be tested, if not or you are unsure best to have it checked at the vets.
