I want to return the product because it does not fit my dog, You never have a size small available and your representative suggested I order a size medium. I advised him my dog is small and weighs only 21 pounds. You advertise a 90 day return policy, so like every other reputable company I deal with I felt safe in ordering the medium size. I am disappointed that Pawvie would not send me a return authorization. My dog has a torn CCL and is in pain when she stands or walks.
