We are excited to bring to you the beef backstrap in a pack of 50! Like all of our beef products, these are from free-range, grass-fed cows from South America and contain no additives or preservatives. They are a cartilage piece from the back and have a similar consistency to that of the beef tendon (but much bigger). Although they may not last as long as a bully stick, they are sure to add variety to your pooch's treat regime! You'll also be happy to know these chews have little to no odor!
