Healers Dog Boots for Paw Protection with Non Slip Sole, Reflective Pet Booties, 1-Pair Urban Walkers are sold in pairs for better sizing. Please measure your pet's front and back paws as the back paws can be slightly smaller than the front paws. This protective dog boot is made with a strong, non-skid sole that is perfect for slippery surfaces and all terrains. The top layer of fabric is a breathable shoe mesh that dries quickly and allows air flow so bacterias do not build up inside. The wrap-around design and high-tensile strength hook enable a good, strong fit that will hold in place. Inside each boot is a non-slip lining that helps to prevent your dog's paw from twisting. Urban Walkers allow natural motion and feel. Made in the USA with the highest quality materials.
