Made with loads of real pork liver and a little cheese these treats are delicious and make the perfect healthy dog treat. Pork liver is a nutrient-rich organ meat that most dogs readily eat. Liver can provide your dog with protein, fat and vitamin A, all of which help him stay healthy. Pork liver is also a good source of copper, iron, niacin, phosphorus and zinc. It provides many B vitamins, omega-3 and omega-6 fatty acids, and essential amino acids your dog needs from his diet to keep him healthy. Our pork and cheese is sourced from Canadian farms and processed in Federally inspected plants.
