I dont understand how there are so many good reviews. They have no shaping, so they dont allow the dog to bend her feet. She would have to walk on tip toe ! This is particularly bad because I got them to help her arthritis. As far as I can tell they only fit when the 'wrist' isnt bent, so the foot cant be flat on the floor. Never used boots before but surely this cant be right ?
