One of the most important nutrients for dogs is protein. Protein is made up of amino acids, which are the building blocks that create strong muscles and repair body tissues. Because the dog can only make half of the amino acids he needs, the other amino acids (called essential amino acids) must be provided by the diet. Common ingredients such as chicken, egg, beef, turkey, lamb, soybeans, and fish meal provide necessary protein levels.
