Minis do make good companions to other full size horses and if things get out of hand, they will get out of the way. They are not stupid! However, please treat them like horses and not babies. No matter what they size, they will bite, kick and misbehave just as much as a full grown horse. You get kicked or bitten by a mini, you will know about it! You have a mini on the end of a lead rope wants to play up...you have got your hands full just like any other horse. Enjoy your horses and keep a sensible head on. In the animal world, mini doesn't mean sweet and cute!
