Hi dchassett
I don’t know how much help I’ll be, but I’ll try. I believe the leg trembling could be because she is losing muscle mass in her rear legs. I’ve seen that in dogs with spinal arthritis and degenerative disc disease. As they lose muscle, their remaining muscle fatigues faster. I think there is probably not much you can do about it, except to make sure that she gets regular walks and consistant gentle exercise. As far as the joint supplement, Dasuquin is the one vets recommend because it’s made by the makers of Cosequin, and cosequin actually has some research behind them. I have always had the best results with supplements containing MSM and HA. I have many times bought MSM seperately because I wanted to try a supplement that didn’t have it. The one that I have had the absolute best results with was called Joint Armor.
