Food & NutritionCan I switch my dog from grain-free Blue Buffalo to regular food?
Most pets do not have grain allergies. More commonly it's the protein source that causes allergies. For most dogs, grain free is not recommended. For general food, I recommend the brand Royal Canin. It is low residue and highly digestible and this results in great stool quality, minimal quantity and low odor. I also like Nutro and Purina Pro Plan. If you want to rule out a food allergy, the fastest way is a proper food trial using a hydrolyzed protein diet. I hope this helps.
