I'm pretty sure he was shown in futurity shows before I got him, so he at least used to know that hustle and bustle. He also had at least one other horse with him since birth (his brother who was also for sale when I bought him).
I wanted to use a calming aid more so he doesn't hurt himslef in the first day there. He's a relatively bright boy, and I've trained him to ride in traffic, but I have this sneaky suspision that he might walk wout of the trailor, take a look around, try to bolt into traffic, hurt himself (most likely fall down as I catch him on the lead rope), then associate this new place with pain.
I feel like if he gets through the first day without an accident, he'll be ok. I'm more than capable of introducing him to new horses slowly.
