It is hard to take pictures of little hairless spots with a camera phone.. but I am pretty sure my new puppy has demodectic mange. Its localized and the skin looks healthy... just missing some hair! Has anyone else had this with their puppies? I have had a couple of fosters that had it, and in a couple of months it was gone and to my knowledge never came back again. it usually starts to happens if one of the females come in heat (where i foster does not alter dogs until they are adopted) Is it common to take your dog to the vet for it? I understand if the hairloss is getting worse, or its seems pretty bad you should go to the vet, but if it is just a few spots here and there... or a little on the eye lid I was always told that it was fine and not to worry unless it got worse. Thanks! here is a picture of some hairloss on the face. it is also found on his legs, and the corner of his mouth. I counted three spots on his leg and one corner of his mouth. and what you see on this picture.
