My guinea pig has widespread skin marks. Could it be ringworm or lice?

It is difficult to make an assessment on what this might be with a visual. Skin issues such as these can be due to a number of different causes including parasites (mites, lice or fleas), Ringworm, skin infections, trauma or even some endocrine diseases such as Cushibgs disease. You should take Bojangles to the veterianarian as soon as possible. You could also request a consult with an expert where you can post pictures and ask more questions.

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.

Looks like ringworm but you must understand that I really can’t be 100% sure just by looking at a photo. You should have your vet examine him. ( https://mobile.petcoach.co/amp/article/ringworm-in-rabbits-and-guinea-pigs-transmission-signs-diag )

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. Thanks for using Petco Pet Education Center, formerly Petcoach! I hope this is helpful!

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!

It could just be dirt or dander, but lice are also common in guinea pigs. If you have any concerns that they could be lice then I would encourage you to have her seen by your veterinarian as soon as possible. Best of luck and thank you for using Pet Coach.

Guinea pigs often get ringworm, so I would encourage you to have a follow up appointment with your veterinarian and discuss testing and possibly treating for ringworm. In the meantime please practice good hygiene after handling him as human can be infected with ringworm too. Best of luck and thank you for using Pet Coach.
