As one of the most common dog treat in the pet retail industry, jerky is a great low fat, high protein snack for pups. We use only the good cuts - no leftovers or by-products! Our jerky products are JUST jerky! We want the best so we add ZERO additives or fillers, meaning NO SALT, NO GLYCERIN, and NO antibiotics or growth hormones are used in the life cycle process. We use just meat - coming from 100% pasture raised duck with nothing ever added.
