pointing

My instructor pointed out to me that i have be sticking my toes out in dressage alot. So i realy want to know what i can do to stop my toes. Do you have any tricks or tips to stop them from doing that? Thanks :)

My horse is completely sound under saddle, but when he stands, he weight bears on one or other other hind foot, and "points" the toe of the other. We recently had his hocks injected and I thought it might help, but he still stands the same way. He is also resistant to letting me clean his hind...
