Does my horse know how lucky he is to have the whole summer off? No, he doesn't. He thinks that's how it should always be.
I try to clop around on him at least three times a week, but he has 24/7 access to turnout, so if I don't it is not the end of the world. I find though, that the more I ride him the more I am motivated to ride. When life interferes and I can't ride for a few days, I start remembering how much he wants not to be ridden instead of how much I want to ride. The more you ride, the more you can't do without it.
