I saw the other day that my guinea pig had a small bald spot on the side of his neck. He seems very happy and healthy, but he self-barbers and bites his own fur a lot.. Not so much scratching. When I first got him I took him to the vet, who told me he didnt believe it was mites or a funal infection because the scratching/biting was not constant, but I'm still really worried about him. When I saw the bald spot I kind of panicked. the skin isnt scarred or hurt, its just a small patch of fur missing. And my guinea pig still bites his fur a lot... Usually when I'm not actively playing/talking to him. Is he okay? I dont know what to do and I dont want to sit back and do nothing if theres a potential problem
i'll attach a picture of the bald spot
