My guinea pig has a hairless spot on her nose. Should I be worried?

Hello, Thanks for sending good pictures! I have a couple of suspicions about what is going on with Reeses' skin. Ringworm, which is a type of skin fungus, is very common in guinea pigs. Testing for this involves taking a hair sample from the area for something called a DTM culture test. This infection can spread very quickly over the entire pig's body and also spread to people. Mites are a type of skin parasite that can also affect guinea pigs and cause hair loss. They cause severe itchiness that can sometimes lead to seizures. This is generally tested for with looking at a scrape of the skin under the microscope. Both of these ailments generally require a course of topical and/or oral medications, along with regular cleaning of his environment during the treatment period to prevent re-infection. I would recommend taking Reeses into a veterinarian that's familiar with guinea pigs and having the area examined to determine the best course of diagnostics and treatment.

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.

Hi there! As ringworm is a fungus, they can contract it from other guinea pigs, from humans, or from contaminated objects, such as bedding. Symptoms of ringworm in guinea pigs are usually bald spots around the ears, neck, and face that can spread along the rest of the body. They can also have crusty, flaky lesions in the middle. If you suspect that your guinea pig has ringworm, I strongly suggest taking preventative measures when handling him or her - good handwashing is essential as ringworm can be transmitted to humans. A visit to the vet is also in order - they will likely take a small sample of your GP's hair to culture for the fungus. They may also use a type of black light called a Woods lamp to examine his or her skin as the ringworm fungus usually fluoresces. If your GP does have ringworm, the vet will likely prescribe a topical or oral antifungal, or a combination of the two. There are other skin conditions that can cause bald spots as well, such as mites, that the vet can also check for. Good luck, and I hope that your piggy gets well soon!

Poor Betty this looks sore! I would say this is due to an infection of some sort. It could be bacterial even coming up from the resp tract but the flouroquinilone should have helped. Otherwise it may be a parasite or fungus such as ringworm. I would get a skin scrape checked and have a hair brushing sent off for ringworm. I know you have tried antifungal cream, sometimes canestan works but at times they need stringer treatment from the vet. You could also try an antiparasite treatment such as xeno.

A small amount of dryness on the ears of guinea pigs can be normal. If Lily is not scratching at her ears and there are no other lesions present on her skin, then I would recommend you just monitor the condition for now. If however she seems itchy, lethargic, or her coat and/or skin is abnormal in other spots, I would recommend taking her in to your vet to be examined. It is true that guinea pigs frequently get ringworm infections but they can also get bacterial infections and mite infestations as well. A thorough exam by your vet will be able to determine which is causing the problem. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hi, thanks for using PetCoach. There are several reasons a guinea pig may lose fur. The primary differentials for hair loss are parasites or fungal infection/ringworm. Vitamin C deficiency or scurvy can also cause hair loss. I recommend a visit with a veterinarian that treats small mammals to help find out why Pumpkin has a bald spot.

Thank you for using Petco Pet Education Center, formerly Petcoach. I recommend taking Looey in to a vet that see GPs when it is safe to do so. They can get lice or ringworm or it may be some other skin disorder. If you would like to post again with some pictures this may help us guide you a little more.
