The first tackle we have is the door banging, just like my ID did, so I put the quick kick back on the door, as i hate shouting stop it all the time, and this way they learn that when they kick the door a spray comes from no where and don't associate it with humans being mean. My ID mare stopped relatively quickly, I always worry about their hooves continually banging on the door on the structure of their hooves also ricochet on the joints and knees.
