The bad part is if you have already trained a horse and treated it with ears back getitia said you can really never correct it.
I'm hoping this isn't true...though I suppose it would depend upon the individual horse.
With a great deal of patience (on both our parts), Mingus is finally learning as a 6 year old to give ears. I believe that this is such a reflexive action that an adult horse who has not been "pretty ear trained" is hardly aware of what they are doing with their ears, so the trick is communication.
Mingus loves to show and to show off, but he seems to think he looks darned fine with his ears back, so we've been working on this with clicker training, crinkle wrappers, and the luscious, tender grass that is only given for good ears.
We work on this separately from all other show set-up training, as don't want to confuse him. Since he has such bad ear habits, at first he didn't have a clueas to what I wanted, and I had to essentially catch him doing it right. I ask for ears while crinkling or showing that "ear"esistable treat, then click the instance he gives ears. We work on this for just a short time, but many times a day, every day. Today is the first day that he has really seemed to get what I want. While the jury is still out, he seems to be learning. The biggest key for us has been P A T I E N C E .
Interestingly, he is beginning to give ears when asked to do anything, including jumping...
I have to admit, however, that so far Flash, who is usually a very fast learner, is resisting all efforts to teach pretty ears...
