Though it may seem like it at times, not all dogs have cast-iron stomachs. This formula is built to help address your pet's sensitive stomach. A combination of potatoes and egg protein makes this limited-ingredient formula easy to digest for sensitive dogs. Psyllium seed husk, a source of beneficial fiber, helps support proper digestion, and probiotic strains that are native to the canine GI tract are added. Diamond CARE Sensitive Stomach Formula for Adult Dogs is safe for prolonged use, so if you find it helps your dog, you can keep them on it. But like anything concerning your pet's health, check with your veterinarian first.
