100% All Natural Bully Sticks. No artifical preservatives or chemicals added! Our Bully Sticks come from Brazilian Free-Range cattle and they are hung vertically for drying and drainage. Since our bully sticks are processed in this manner, there is no medium for bacterial growth. Bacterial growth is the cause of the strong smell you will find in many bully sticks in the marketplace. Also, many manufacturers add smoke flavor to cover this smell, or process their sticks with peroxide or bleach to cover the smell. Our product is low odor, all natural with no additives or preservatives. Bully sticks are great for teeth and gums helping to reduce tartar!
