Animal by-products deliver essential protein, vitamins, and minerals. However, with all Just Right custom formulas, the first ingredient is always real meat. When Just Right incorporates animal by-products, they only include liver, kidneys, and other clean organs (the parts of animals your dog would naturally eat in a wild environment). When they use animal by-products, they focus on keeping safe, nutritious ingredients from going to waste (since humans typically avoid these). They’re good for pups, so they’re included in each custom blend.
