All of our Nature's Own Pet Chews Bully Sticks come from food-grade raw material. Food-grade means fit for human consumption. Our Bully Sticks are washed 3 times in warm water to remove excess fluids and are hung vertically to cook. The hanging allows any juices to drip off the puzzle instead of basting into them. Our Bully Bites are admixture of all types of our Bully Sticks. Our 1 lb. bags equal in weight to more than 10 Regular 12” Bully Sticks and our 8 oz. bag is equal in weight to more that 5 Regular 12” Bully Sticks . A Great Value!
