My puppy is losing hair

Possibly mange? That is just what came to mind, I really don't know. There's more than one type of mange, and it can cause the hair to fall out I believe. I would have a vet check it out to determine the cause.

Could be fleas, could be allergies, could be mange, could be a myriad of things. I'd recommend having a vet look at it just to be safe.
