Lamb lung is the sole ingredient for this product which is a natural source of high protein and a great treat for dogs on a lamb diet. This product is packaged in a resealable canister to help keep these treats fresh. Don't pay more for the other lung products on the market, and reward your dog with this nutritional Merrick treat.
