Thera-Paw Boots are the same for the front and back paws, and for the left and right legs. Make sure you correctly measure the affected paw prior to purchase. If the paw is injured or temporarily bandaged, you can measure the other paw (other front paw or other back paw) AS LONG AS the paws are deemed similar in size. Determine your dog’s size from our Thera-Paw Boot Sizing Chart.
