Secondly, have him evaluated by a vet and chiro. There could be some issues there. I had Sky tripping up a storm when I first got him come to find it was his feet and also his lack of experience. Got his feet under control and then put poles around the arena to practice picking his feet up.
You mentioned that he slid his hind legs and smacked his front legs?? What kind of footing was this on?
We got his feet done as soon as he started tripping and our farrier is very good and I trust him but I will be posting pics of his hooves later for another poster to see.
When he tripped with his back legs we were in the indoor arena, it's sand but it isn't crazy deep like some arenas.
