Answer
There could be a number of things wrong iwth your dog like not getting the right nutrition in his food, it could be fleas, or it could be stress, maybe try giving him a flea bath or try feeding him extra vitamins theres something called brewers yeast that u can get from the pet store that is a good vitamin supplement
