What is in large breed food that is not in an all size food? What makes it better for large breeds?
Answer by • Jul 26, 2018
Large breed formulas tend to have higher concentration of glucosamine and chondroitin sulfate which help develop the cartilage and bone. They also tend to have leaner proteins for strong muscle development to help support the larger frames.
