Savory Steak and Kidney Pie may sound gross to most of us but your dogs will go wild over the flavor! Kidney is a good source of Protein, Vitamin C, Zinc, Vitamin A, Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Iron, Phosphorus, Copper and Selenium. And what dog doesn't like the flavor of steak. As with all our treats they are packaged in 6 1/2 oz. resealable bags and are preservative free.
