Diamond Naturals Extreme Athlete 40LB

Switching my dog to this high-protein formula made a noticeable difference in his stamina on our long runs. The 40-pound bag lasts over a month for my medium-sized athlete, and his coat looks shinier than ever.

Our agility trainer recommended this for the 40-pound bag's protein focus, and it’s held up through triple weekend workouts. The kibble size is perfect for my border collie, and he finishes every bowl without me adding toppers.

My pointer mix has way more energy since we switched to this 40-pound bag, and I love that the first ingredient is real meat. It keeps his coat shiny and his digestion regular even with all his running around. This is the only food that’s held up to his athletic lifestyle.
