Beef Liver is a nutrient-rich organ meat that can provide your dog with protein, vitamin A, B vitamins, omega-3 and omega-6 fatty acids. In fact, Omega 3 & Omega 6 fatty acids have various health benefits for your dog. It is also a good source of iron, copper, niacin, zinc, phosphorus and essential amino acids your dog needs to keep him healthy. Our Beef Liver not only fights infection in dogs but it is also helps keep your dogs skin healthy & coat shiny! Keep in mind, like the rest of Mika & Sammy’s Dehydrated Treats they’re also safe for humans and a favorite among our feline friends!
