I have a medicine ball at home that used to get a lot of use, but now its main job is to serve as a place to stretch my back and ribs. Occasionally I'll sit on it and work my pelvis too. I assumed the horse ball would be about the same, so I was surprised at its heaviness when I pulled it out of the box.
Based on recommendations by friends, I also ordered the cover. As surprised as I was by the heft of the ball, I was initially concerned about the petiteness of the cover. Once I shook it open, it turned out to be appropriately large and fairly sturdy.
Speedy would have a heart attack if I put this ball anywhere near his stall. Knowing that, I purposely aired it up where he could observe the process, but I made sure to stay far enough away that he didn't feel threatened. I knew Izzy would have no such concerns.
Once it was ready for play, I gently nudged it out of the tack room doorway so that Speedy could get an eyeful. As anticipated, he gave a full on DANGER snort and back peddled to the far side of his paddock.
