My Paso Fino was the definition of impatience but she's getting better. Really I think a lot of it comes down to the maturity of the handler, and that the horse will reflect that; and also, the presence of the other horses. I have her tied up with Bow, who is pretty patient at being tied, and she seems to have caught on to that by being with him. Shes getting better at standing still for mounting, too. I think it's just repetition and not putting energy into their impatience. Scorning them for being impatience is being impatient, also, and I think they feed off of and mirror that. Not that I'm always so patient. Both of my horses are a test of my patience. She's also one to take off bolting back to the house, but I've been ponying her off Bow during our rides and then riding her immediately afterwards and shes gotten less in the habit of rushing back home that way. I've also stopped dismounting her anywhere near the mounting block or hitching rail. And, lately, she's stopped wanting to rush over there as a result. I'm not really sure if you can teach them patience. I think this is something we have to embody in ourselves.
