Bully Sticks. Our bully sticks come from free-range, grass-fed Brazilian cattle, the greatest cattle in the world. No growth hormones or antibiotics are used on the cattle. No preservatives or chemicals are used in or on our bully sticks and they are produced in a USDA approved facility. Our sticks are hand-sorted and are 5/8″ – 7/8″ thick (measured on the thickest side). Watch your dog work at his favorite treat for many minutes to the next couple days. Choose between 6, 10, 15, 30, or 60 bully sticks. 100% all natural, grass fed beef. No growth hormones or antibiotics. Enjoy a happy puppy.
