Hi there. Bumps on the skin are usually related to allergies to the protein in the food, we don't see many grain allergies in pets. I would suggest either the skin support diet from Royal Canin because it also has urinary support, OR their hypoallergenic food called hydrolyzed protein which has urinary support as well. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach!
