Yeah, I am very careful with him even on the ground. He has done a 180 as far as ground manners and respects my space very well. I am never out with him alone, and if I feel I shouldn't be doing something, my husband takes over and does stuff (I must say it has been VERY hard to step aside and let him do it). Usually I just go out and brush and love on him. I have been practicing squaring up, and also backing and leading better. Every once in a while I will throw him in the roundpen and free lunge him. I also walk him up and down hills to try to build his muscle. That's the extent of what I do.
My husband does the fun stuff, shoveling poop, picking feet, etc.
I am also very fortunate with where he is at. A friend of mine, the one in the video, takes very good care of Onyx for me, and I give her advice and help her with her colt, although that doesn't happen nearly as much anymore because of my pregnancy. Usually now I just kind of "coach" her.
Really I am not worried about my horse hurting me. I am more wary of the 11 month old colt that he is in with!
