Slip-N-Lock EverestThe Slip N Lock dog rope leash combines a collar and leash into one adjustable, easy to use piece. Use one of the adjustable rubber sliders to get the best fit around your dog's neck. The other rubber slider locks the position and ensures the neck loop of the leash stays in place through your walk. Great for use during training, for difficult to train dogs, and for dogs adjusting to a collar or regular leash. Soft, pliable polyester rope, one size
