We are excited to bring to you, the beef back strap. 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). They are approximately 6 inch - 8 inch long per piece and have little to no odor. Although they may not last as long as a bully stick, they are sure to add variety to your pooch's treat regime!
