I'm just past the second dose on my older border collie, and it has been a good thing for him. But I would hesitate to call it a miracle. He's somewhat more active and flexible, but he still has some trouble climbing steps and stairs.

He also loves the cold, and he's always more active in the winter anyway. I would say he's close to the level he was last winter instead of slightly declined. That's great, but not miraculous.

We'll stick with the regimen and see if he continues to improve. I'll upgrade my judgement if he starts climbing stairs again.
