If your puppy is a breed that you expect to weigh 50 pounds or more when fully grown, you may want to start your puppy on a food that is specially suited to his size. Purina Puppy Chow Large Breed Formula is formulated to give your large breed puppy the nutrition needed for those months of growing ahead. It takes up to two years for some large breeds to reach maturity. Puppy Chow Large Breed formula uses real chicken protein to support muscle and appropriate amounts of calcium for bones, plus a balanced mix of vitamins and minerals to support your puppy's developing body. Just as important, Puppy Chow Large Breed Formula is highly digestible, which ensures that your puppy will receive all the important nutrients he needs to be his incredible best. Be aware that overfeeding can be harmful, especially for large breed puppies. Check your puppy's weight regularly and adjust his food intake, as necessary, to maintain a lean body condition.
