Our new Natural Balance® Potato & Duck Treats are a proven formula for dogs with allergies based on our unique protein and carbohydrate blend. Some dogs may be highly sensitive to commonly used proteins, carbohydrates and food additives in their diet. Allergic reactions can lead to irritable bowel, upset stomach, and a number of skin problems. Natural Balance® has created our new Potato and Duck Formula Diet for dogs, which combines duck, a source of animal protein that most dogs have not been exposed to, and fresh potatoes, a source of carbohydrate not commonly found in dog foods.
