I am really pleased with these my older dog has arthritis in her hips they always look very protruded due to the fluid aswell ,she's been sore with them not able to jump up on the bed and other stuff ,I really just came accross these thinking they won't work but ill give them a try because I was getting worried of her swelling in the hips ,now 2 weeks on she is a completely different dog her swelling has gone right down she's like a spring up and down on the bed ragging her toys like a puppy and generally so happy in the self ill be sticking to these for the foreseeable I am very please they actually work 100% .
