Another question from me:)...my horse wants to jump into the trailer while loading. When we first loaded him into our trailer he started to go in completely fine, then once his foot hit the floor and it banged really loudly, he backed out and was reluctant to walk in again, so he took a leap in. I think it's because he has shoes on, and our trailer's a step up with a wooden floor, so it makes it much louder. When we go to load he'll get up to it like he's going to get in, they'll he'll back up a few steps, then I'll tug on his lead rope and he'll come forward and jump in. How can I get him to just walk in?
