Fuzzy and Moe
I have 2 guinea pigs and have noticed that one has small black shiney lumps on one of his ears and the other has similar on one of his ears and a circle shaped patch of hair missing off his shoulder that is dry and looks raw around the edges similar to a ringworm on a human. I wormed them today. I brought them 2 and a half months ago. They are approx 6 months old but the one with the missing fur is a bit older. Could they have mites? If not, what might it be? They are not off their food or water at all.
