The Winnie Lou Bison Liver Bites Dog Treats are a su-paw tasty way to reward your best friend. These snacks are made with bison liver and nothing else, so they’re paw-fect for pups with food sensitivities. Liver is packed full of vitamins A and B, which are essential for your best friend’s health. B vitamins help your pup synthesize proteins and turn carbs into glucose or energy. Vitamin A supports your furbaby’s skin, coat, nerve, and muscle function. These treats are also a great source of iron, copper, and zinc. Paw-some!
