From what you are posting you are probably dealing more with behavior/habit then need for basic health. It is good to keep up with yearly or semi-yearly health checks with your vet. I have one that is laid back and so easy, I can almost miss a problem. Then I have one that is such a pain, just has to stay busy, its hard not to jump to a problem. 🙂
You didn’t mention any of these but I would call it the we would like health group. The I wish his hooves where healthier or boy he doesn’t move quite as well as when he was younger, or ?? smartpak does have some nice supplements for this area.
