Sometimes a standard adult formula isn’t enough for dogs with delicate digestion, food intolerances and allergies. Ultra Dog Hypo Allergenic has been scientifically developed by our veterinarian and pet nutritionist to contain ostrich and potato as novel sources of protein and carbohydrates. That allows your dog’s diet a break from common ingredient sources found in most dry dog foods. Ostrich and Potato are used to allow your dog’s digestive and immune system to have a break from its battle against common food allergens, thereby contributing to the overall health and longevity of your dog.
