Answer 2

This could be caused by an allergy either from its food, or from something in the environment. Or it could be allergic to fleas. I would take the dog to the vet and have it checked out. Good luck.

Answer 3

Actually it sounds like Mange. It's treatable and the hair will grow back most of the time. Definitley get him/her to the vet. They will give you a regiment to get rid of it. Also could be fleas, they have been an epidemic this year due to the weather conditions, but it does sounds like mange.
