All of our 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 pizzle instead of basting into them. Our Bully Bites are a mixture of all types of our Bully Sticks. Our 1 lb. bag is equal in weight to more than 10 Regular 12 in Bully Sticks.
