Ruffwear Bark'n Boot Liners enhance the fit, upgrade the performance, and improve the comfort of our dog boots. Pair with Grip Trex, Summit Trex, or Polar Trex boots to inspire a little more confidence and excitement in their step. They’re made with stretchy, moisture-wicking fabric and a tapered cuff that’s comfortable and stays in place. The curved “claw box” design follows your dog’s paw anatomy, minimizes bulk, and is ideal for dogs with dew claws. Available in sets of 2 liners and 4 liners.
