Little Ones
Adult Guinea Pig
My guinea pigs hair began thinning a while ago, we treated him for mites and fungal in case but he had neither. Today we've noticed dramatic hair loss around the rump. Hes lost the hair on both of his rear sides as well as his rear end. There are almost bald spots. It's so close to hardly being fur at all. It doesn't look like it's any parasite, we will still give him a course of ivermectin but I'm not sure if that's what it is. It was hard to photograph but any ideas?
