Hi, I've owned guinea pigs for over 7 years now and recently mine have passed away from old age. It's my first time getting baby guinea pigs from a local petco, but I was looking closer at the one I got yesterday (waited to fully look at it because I did not want to stress him out too much) and he has a weird patch on his stomach. He isn't neutered and I'm not to sure what would be the cause. I think it might be ringworm but I'm not to sure, I'm a bit worried and I won't be able to get to the vet until 2 more days because it's 3 hours away and I have a busy work schedule. I really want to see if i can figure out if it is ring worm and if maybe there's something I can buy to help treat it. I wish I knew how to attach a photo, if anyone knows how and could tell me that'd be great.
