My guinea pig, Piper, has a small amount of hair loss on his back. There no way another pig could be biting him/his fur off. Theres a tiny little strand of hair covering it, and when i lift it up I can see a pacth of his skin, with tiny bits of hair trying to grow, but they are very very small. My guinea pig is a short haired guinea pig. I do not know any health issues he may have had in the past, or how old he may be.
Thank you in advance!
