Just so you guys know, your shoes are the BEST ever! I have an Australian Cattle Dog who, for some unknown reason, has spinal fusion from her neck to her tail. The only vertebrae that aren’t fused are the ones to move her neck and shoulders. The fusion was pinching the nerves in her hind legs so she had to have surgery in December. She’s lost a lot of the strength in her back legs so the shoes work great for her getting traction on the tile and other smooth surfaces! Her neuro surgeon was very impressed with the shoes! She also knows the shoes are good for her and she will wait for me to put them on her in the morning before she goes outside. Just thought I’d try the seat belts and rear harness to see if they are as great as the shoes! Thanks! Susan
