I give Jackson 1/2 of these jerky sticks every night.... just as a preventative. He has no joint problems, etc, but he does a lot of running, jumping, agility, swimming, and gets a ton of exercise. So I figure it can't hurt. I don't really know if these kinds of treats do anything.

He will be 4 next week and no knee or joint issues thus far -- do you think giving him something like Cosequin is a waste? Since he is so highly active?
