Dog nutrition: Key factors beyond protein percentages

The trend of ‘protein-maxxing’—maximizing dietary protein intake to support metabolism, weight management, and muscle growth—is increasingly influencing pet nutrition alongside human dietary habits.

While the Association of American Feed Control Officials (AAFCO) establishes minimum protein requirements for dog food (18% for adult dogs and 22.5% for puppies), experts suggest that a high protein percentage alone does not provide a complete picture of nutritional value. Key considerations for pet owners include the source of the protein and how effectively a dog can digest and utilize those nutrients to support muscle maintenance, tissue repair, and skin and coat health.
