We got our eight year old Shepherd Dakota from the local shepherd rescue outfit at two years old. She had great spirit but it took her a while to stand up. I believe she had been continually kept in a crate. She was a mess. It took me two years to get her strong enough to jog with me but she always hesitated to jump in the truck. I was considering rigging a ramp for her. After three weeks of Liquid-Vet Joint Formula Dakota jumps in unprompted and is clearly more confident in her hips. I am truly amazed. I highly recommend this product!
