you are !
Many people tell me ” yes, but I’m not the trainer !” but you are. with every interaction you have with your horse, you ARE TEACHING IT SOMETHING, for good or bad.
Besides, training doesn’t just happen in the arena. Pay attention to your horse as soon as you walk into his stall or put the halter on, how’s he responding? Is it the way you want him to respond? and are you allowing, correcting or encouraging him?
If your trainer (or you) has taught your horse all the right things, you need to continue to reinforce it.
Let’s say, you let your horse rub it’s face on you and push you over, you are allowing him, encouraging him, and teaching him, that’s okay to do!
Be thoughtful when handling horses, you may encourage behaviour you don’t want.
