Jenner Von Jenner says these are the best shoes I have ever used! We were first introduced to the shoes at Tail Waggers in Mammoth Lakes California where the terrain can be very abrasive to a dogs pads, and these shoes are a life saver. We can go on 12+ mile hikes a day with out worrying about Jenner’s paws. Jenner is a powerful 105 pound dog and these shoes stay on while running, walking or swimming. Looking forward to trying the new improved shoe!
