We're wondering the best dog food for our allergy prone golden? She's 9 months and been on adult dog food for a while due to UTI's at an early age. We found Blue food to be the culprit to her UTI, but now she is having trouble with Taste of the Wild grain free. We had her on lamb and rice, and now salmon and sweet potato, but there is a common ingredient in both that she must be having trouble with. We're on a trial of Clariton which seems to be helping, but we'd like a better long term solution. Is there a good dog food that can be recommended? It could also be a household allergy, but I'm thinking it's probably food related because it seems worse after she eats? Thanks for your help!
