Our healthy 4 year old Golden has been on Gentle Giant Dry Chicken dog food for a couple of years but recently has developed very loose, unformed stools. After antibiotics and Pro Biotics and a gradual change of dog food to Royal Canin Fiber Response, his stools firmed up but due to the high fiber content in the food, stools are excessive. We welcome any suggestions for a dog food that creates less stool while still firm but are not interested in a Grain Free or Raw diet due to the DCM issues? Also, prefer to stay away from fish based foods as I''m allegric to that. My breeder feeds Eukunuba Large Breed but there is is a lot of filler in there such as corn, wheat, gluten and chicken by products. Noticed the same ingredients are in Purina Pro Plan (another food recommended for firming stools) so obviously prefer not to go there. Additionally, I noticed that the highly rated top dog foods are expensive e.g. Stella's, Honest Kitchen and so on, kind of makes you wonder if these companies are sponsoring the dog food article. Thank you for any and all suggestions!
