SAFETY FIRST: The Bow Wow Buddy is a durable, easy-to-use, veterinarian-vetted, and dog-approved device that tightly secures bully sticks, preventing dogs from choking on the tail-end of the treat. It is best used together with Bow Wow Labs hand-selected Thick or Jumbo Safe Fit Bully Sticks, ensuring a perfect fit. CHOOSE YOUR SIZE: Be sure to select the right size Bow Wow Buddy and bully sticks based on your dog’s weight. Our Large Bow Wow Buddy is designed for dogs that weigh 50-75 lbs. and fit perfectly with Thick or Jumbo Safe Fit Bully Sticks from Bow Wow Labs. We have sizes to fit every dog breed. EASY TO USE: Simply insert a properly-sized bully stick, twist the tightening screw to lock the stick in place, and let your dog get to chewing. We recommend Bow Wow Labs Thick or Jumbo Safe Fit Bully Sticks to make sure they are just the right size.
