With food allergies dogs can have hive like lumps over their body, red itchy skin & diarrhea & other symtoms, it doesnt happen straight after eating, can take a couple of days for the reaction to show, maybe he needs his fur trimmed as summer is coming up if ur in America..vets normally have real good shampoos & conditioners for dry skin, I found shampoos & matching conditioner with oatmeal have helped my boys skin..
