I'd say that horse has got her number. He's not really comfortable with loading in the trailer and so far, who ever owned him has been able to make him get in. But now he's figured out that if he pitches a big enough fit, he don't have to. She's gonna need to work with him on it, and if she doesn't between now and your next trailride, I'd bet money that he ain't gonna get in. Balky trailer loading is one of the most aggravating things I can think of.
I had worked with Waylon a few weeks ago for the whole weekend and he was fine. ....walked right into the trailer to go home from the cabin. The next weekend he walked right into the trailer to go down to the cabin, On the return trip it took him about 10 minutes to get in. I guess he realizes he is going for a two hour ride and doesn't like that. I will work with him again this coming week,just going in and out ....any other suggestions?
