| Re: Back legs? Shelby also has HD and is slow to get up - once she's up and stretched, she's good to go. She also cannot jump (with hind legs leaving the ground) from a standing position. She also needs help in the rear when getting into a truck or SUV. We have her on GlycoFlex as well and it seems to be helping. Vet check and X-rays will let you know what's going on. |
