I took the trailer home and gave it a serious deep cleaning on Sunday (which was hysterical - if you've never done a self service high pressure car wash with an 8 year old, you haven't lived).
Then decided I should get Smokey to load when we went to the barn to drop it off..
Only he wouldn't. As usual, high pressure tactics don't work well with Smokey. He just gets weirded out. By the end (I had to cut it short, but we ended on a good note), he was walking up to the trailer calmly, but not quite loading all the way (got all four hooves in, just not quite in position). I'll try again tomorrow when I don't have so many time constraints.
Isn't it odd for him to stop loading? He was doing perfect, then Sunday was just a bit flakey, now zip.
The trainer says it's a young horse thing. Sometimes things just stop working and you have to restart. Does that make sense? Everything else is working...
One funny thing, at the end when I was just rewarding him for standing near it, he sniffed the trailer very intently - I imagine after our high pressure wash it smells really different.
I wonder if it needs some funk back in there.
