I bought this wrist hugger to help my arthritic dog, who experiences some pain and weakness in her wrist. I followed the measurements and ordered a medium as she is 32 pounds. Unfortunately, this product never worked for my dog and would slide off her wrist within minutes. No matter how tight I put it on, as soon as she walked to even her water bowl, it slid onto her paw, and she became hesitant to move. This wrist hugger does not stay and is not worth the price, as it did nothing to aid my dog.
