HELPFUL TIPS Adjust feeding amounts as necessary to maintain optimal weight. If you are unsure, ask your veterinarian. New to this food? Mix increasing amounts of your pet's new food with decreasing amounts of the old food over a 7-day period. Keep fresh water available at all times! Your pets nutritional needs may change as they age. Ask your vet at every checkup. To prevent suffocation, keep the packaging out of the reach of pets and children.
