Some puppies can develop adverse reactions to specific foods. That's why Pronature has replaced the wheat, corn, and soy with oats, brewer's rice, and barley. These three grains are easily digested and a good source of energy. They also allow better absorption of nutrients and noticeably reduce stool volume.

In addition to providing all the basic ingredients puppies need, Pronature has adapted the protein and fat content (28% and 18%, respectively) of this formula to satisfy the needs of the majority of breeds.
