Trailer problems are hard to solve, I think because, for the horse, being a afraid makes perfect sense. It isn't a comfortable ride, and it is a scary small place. One of the reasons my friend sold Bay all those years ago was that he wouldn't load in the trailer (easily). But he had an older straight load trailer that I think was just not big enough, and so dark. His next owner (the endurance racer) cured him of loading problems, traveling all over the place like she did, but he now rides in only slant-loads and stock trailers. I wonder if even today I would be able to get him in a straight load. He has preferences!
I do like Arabs too. I love how they stop and 'blow' at little things, but will go forward anyway. I love how they carry themselves. My complaint with the Arab show trends is that "English Pleasure" now means "Park Horse". I had a little Egyptian stallion as a kid who was a 'nice' mover. And always in the ribbons when we were young, but by 1985, I was beginning to have to compete against only park horses, and the old traditional movement couldn't win anymore. I love to watch natural park horses, but they sure have gotten exaggerated.
Here he is, one of the only photos I have of my little Egyptian stallion (very old pic, I am about 16!)
Glad you were able to take her in. My mare is an easy loader into anything ("Oh, boy, is he handsome?"), although we usually go to the shows with my trainer who has a nice slant-load Sooner. I would not use an old straight load any more though, because they ARE dark and narrow and it's harder for a horse to brace himself on turns and stops. Although my mare is not an antsy shipper, I also don't like the low ceilings in the old fashioned trailers.
Endeavor, you would like my T'bred (our vet loves her) she's so untypical of the breed. She will stand to be clipped, injected, shod, medicated, whatever. I clip the inside of her ears and her chin whiskers in the cross-ties and she never moves. She once almost fell asleep while being shod - I was standing at her head rubbing her ears and poll, and her head just started sinking lower and lower. I woke her up because I was afraid she might tip over with one foot up!
(Did I mention that I wear spurs? :-D )
