Poor Coco! He needs to see he veterinarian for some simple diagnostics to check for skin mites and ringworm (which humans can get). These are very common in puppies as are flea allergies (some need something stronger than a topical medication). Food allergies can occur but are much less common. Get him seen today so that you can figure out the cause and get him feeling better quickly.
