Dogs Skin Allergies

My 2 y / o Jack Russell / Shih Tzu Mix scratches, bites and licks on almost constantly on the verge of bald patches on his back. There is no trace of him in chips, and nothing has changed in the household. Its diet consists mainly of canned Alpo, I checked and it does not contain red dye # 40, I was told, can cause skin problems in the breed Shih Tzu. Any suggestions on what may be the cause of her skin problem, or do whatever I can to eliminate or at least improve his condition. if the fish are feeding your dog, then just stop, I am 100% fish causing skin problems, it is a situation to deal with your needs as vet.there is possibilities.h dog has been vaccinated recently? can still be a food allergy dog use plastic plates? skin problems than other allergies, etc related to stress, however, the dog uncomfortable and should be seen and treated in order to feel better my best guess is a food allergy, but you really want to see veterinarian about the red flag here is that you're eating Alpo.
