Recently my vet recommended Glyde powder for dogs for my German Shepherd (Cheppy). I was bit hesitant to buy it as it is a little pricey but gave it a go anyways......and Im glad I did! Glyde has really worked for Cheppy, he is so much more active and not stiff (the poor thing). He's like a pup again :) I also put him on diet which helped too.
