One of the keys to healthy feeding, whether it is the pets main meal or when feeding treats, is variety. Each type of meat or poultry offers your pet different nutritional benefits. And, like you, variety adds interest in what is being fed. Our trail mix features all three of our training proteins in one mix, plus wave added low-fat Vermont Cheddar Cheese - yes, DOGS LOVE CHEESE! Our 4-in-1 trail mix is a good day-in day-out way to feed a mix of healthy protein types anytime your pup earns a reward.
