Natural Balance® Bison & Sweet Potato Canned Formula is a proven formula for dogs with allergies based on our unique protein and carbohydrate blend. No grains such as wheat, barley, rice, or corn. Some dogs may be highly sensitive to food additives in their diet. Allergic reactions can lead to irritable bowel, upset stomach, and a number of skin problems. Natural Balance® has created Bison & Sweet Potato Canned Formula for dogs with these food allergies, along with effective natural ingredients to help rebuild the dog's immune system. Natural Balance® Bison & Sweet Potato Canned Formula is a complete and balanced diet for your dog, yet it has been formulated to complement our Sweet Potato & Bison Formula Dry Formula so dogs with allergies can now have a complete allergen-free diet. For growing puppies, the Canned Food can be mixed with Natural Balance® Sweet Potato & Bison Dry; a mixture that could ease the weaning process and stimulate appetite during this stressful time. For lactating bitches, a gradual increase in food intake is necessary starting around week 8 or 9 of pregnancy. Adding Natural Balance® Bison & Sweet Potato Canned Formula satisfies the increased caloric requirement. Also great for picky-eaters and can help kindle the appetite of older dogs.
