Hi, you have to look at the ingredients, there may be 1 ingredient your dog is very sensitive tooo where your other dogs are OK, when my boy eats, Chicken, Turkey & cooked beef carrots, oats & barley he starts to smell & gets itchy & starts scratching & when he gets his environment allergies in Spring & Summer he gets the hive like lumps all over his body, I bath him in Medicated Malaseb Shampoo weekly or twice a week when he’s real bad…With the Malasab you can bath daily if needed it’s a mild shampoo…. Start keeping a diary for this dog & you’ll start seeing a pattern if it’s Seasonal Environment Allergies & start reading ingredient list & see if there’s an ingredient that keeps being in the kibble when this happens…….
Acana make a Pork & Squash formula maybe try that formula for him or get the “Canidae” Pure Sea, its limited ingredients & the protein Salmon & is high in omega 3 fatty acid what is needed for skin problems….
