Hair Loss bald spot on guinea pigs leg!

Yes, one of my girls has bald spots on the inside of both back feet near the foot. Bald spots around the lower leg (any of the four) is either from self-barbering or cleaning themselves so often that it wears down the fur. I don't think either one is anything to worry about. As long as you've ruled out mites, the skin is not broken and they are other wise happy and healthy.

right now I am treating for mites. And that's good to know that it is from self-barbering/cleaning themselves
