Okay, I'll admit, I just skimmed. So if I repeated anything, I apologize.
I had a horse, Buddy, that we believe was in a trailer accident. He was terribly afraid of trailering. Even if he was tied to the trailer, or anything else for that matter, he would try to rear or back up like a crazy.
I went to a 4-H Boot Camp with him and I looped his lead through the tie-ring of the trailer. He was playin with it while I groomed him. I guess something startled him because he immediately "floored" it backwards and drug my friend's two horse trailer at least six feet before I could un-knot the lead. After that he was traumatized the whole day. My poor baby.
We had a John Lyons trainer at Boot Camp. After the camp he helped us load Buddy to get home. He will only load in big stock trailers now and it still takes from 20min. To an hour. Here's what we tried and did:
Feeding in the trailer - didn't work at all
Friend's brother and friend literally lifted his butt and pushed him into the trailer
Th eonly thing that really worked was when you had an hour, patience, and tons of ideas....
I know this probably didn't help but I had to tell the story.
