My guinea pigs have crusts on nose and mouth, what should I do?

Thanks for using PetCoach. There are several possibilities for Pietje's crusty eyes. The first is to make sure that he has adequate Vitamin C supplement. This needs to be in the form of fresh fruits and veggies as well as fresh food, and Vit C supplement (not in the water). A bit more on feeding https://vcahospitals.com/know-your-pet/guinea-pigs-feeding The other differentials include mites or ringworm. A vet visit can help diagnose either of these conditions. The vet may recommend a fungal culture or skin scraping to make a diagnosis. https://vcahospitals.com/know-your-pet/guinea-pigs-problems I hope this helps.

In my experience the huge majority of skin issues in guinea pigs falls into two categories: mites and fungal. It's uncommon to see flaking skin and hair loss without it being one of these disorders. Ringworm would be a concern and is very common in guinea pigs. Instead of being a worm, it's actually a skin fungus, and doesn't always have the classic "ring" shape. The only way to diagnose ringworm in guinea pigs is doing a fungal culture where you collect hairs and put them on a culture medium. It can take 10-14 days to get a result, though most positives show up within the first week. If you don't want to do the testing then what you can do is treat those scabs with an over the counter anti fungal cream like clotrimazole. It is basically jock itch cream. Apply a thin layer 2 times a day. It won't hurt anything if it is not ringworm but if it is ringworm, it will help. If you are going to shampoo him I would use a medicated shampoo like this one: https://www.1800petmeds.com/Malaseb+Shampoo-prod10667.html Lather it on, let it sit for 5-10 minutes and then rinse. The contact time of the shampoo is very important! This shampoo has an antifungal agent in it as well as an antimicrobial agent. If you try the ringworm cream and shampoo and it doesn't help at all within 7-10 days then I would recommend you get a second opinion from another vet and find a vet that specializes in treating exotic pets as he may have skin mites. Skin mites in these pets will always cause itching, sometimes severe enough to lead to seizures. If he is itchy then skin mites are very likely. Skin mites need to be treated with Ivermectin injections spaced 10-14 days apart and need to be done by a vet. Usually 2-3 injections are needed to clear the mites. If your vet doesn't specialize in treating exotic mammals/pocket pets then I would suggest you find one that does. I found this vet in your area based on your zip code: http://www.acsevh.com/ I hope this helps. Best wishes!

My best guess is that this could be ringworm however it is impossible to tell just by looking at a photo. I suggest you get this spray and apply it 2-3 times daily on the affected area. ( https://www.petco.com/shop/en/petcostore/product/vetericyn-plus-antimicrobial-wound-and-skin-hydrogel-for-pets ) If after a week to 10 days it still is not resolving then you need to take her to a vet for an exam. Wash your hands thoroughly after touching her as ringworm, if it is that, is contagious to people.

Hello. Thank you for using PetCoach! This looks like a ringworm lesion to me. http://www.peteducation.com/article.cfm?c=18+1800&aid=2494 You can try using a topical anti-fungal medication like Clotrimazole to see if it helps. Apply a thin layer to the lesion twice a day. https://www.walmart.com/ip/Antifungal-1-Clotrimazole-USP-Cream-1-oz-tube/950932820 Remember two important things: 1. It can take weeks to months for ringworm to resolve. If you are not making much progress with the cream after a couple weeks I would take her to the vet. They can give you an oral medication to use that may be more effective. 2. Ringworm can be contagious to people so wash your hands thoroughly after handling her. Hope this helps. Best wishes.

Guinea pigs can get bacterial infections, skin mites and ringworm (which you can get as well). It’s hard to say which is present without seeing your veterinarian. Certainly if you see both pigs get lesions or if you start noticing skin issues then you need to take them in. At home you can wash the areas in antibacterial hand soap- rinse it well and be careful not to get it in their eyes, ears or mouth. You can then apply just a dap of coconut oil and rub it in very well. Try to watch her afterwards to make sure she doesn’t lick it off. Change the cage frequently and make sure she is getting plenty of vitamin C. If it worsens, then have her seen by the veterinarian. I hope this helps!!!

Thanks for reaching out about Oreo and including a photo. It is more likely he has an upper respiratory infection and needs antibiotics. Seek an appointment with an exotic companion mammal veterinarian with knowledge of guinea pigs, as some antibiotics can be deleterious to guinea pigs. Good luck.

Your guinea pig may have an upper respiratory infection or a tooth abscess. You should take it to a veterinarian familiar with guinea pigs for a check up of his teeth (guinea pigs often have malocclusions and teeth that are too long). If there is an upper respiratory infection your cavy needs to be treated with injectable antibiotics. Guinea pigs cannot take antibiotics by mouth as it kills their intestinal flora and can indeed kill the guinea pig. Should the crusts go away and your guinea pig eats and drinks well and is happy, then this might have been caused by a draft and it will not need a vet visit.
