Mare won't load or stand on the trailer
My 4yo mare has a hard time loading in the trailer. It is a 2 horse straight load and sometimes she gets on, sometimes she won't. For example, last weekend she got on and off the trailer perfectly fine at both our barn and the place we trailered to. Yesterday, it took us 90 minutes to get her on the trailer at the barn, but she got on the first try to come home. She will put one foot on the ramp and then back up or swing her butt so she is crooked. I got frustrated yesterday because I was late to my lesson. By the end, I had a person with a whip on either side of her so she couldn't swing her butt around. This just made her rear, not go in the trailer. I've tried to do the lunging thing, but 1) she is afraid to touch the ramp and 2) it's hard to lunge on to a straight load trailer. We eventually got her on the trailer by having 1 person lead her, 1 person at the front of the trailer with grain, and another person to shut the butt bar so she couldn't back off like the other times we got her partially on. I realized that she does better when you take the pressure off of her.
I can't have that many people help me load her everytime and I can't help but think that if there was an emergency, I wouldn't be able to load her.
The next problem is standing on the trailer. Once she is on, she starts bucking and rearing. When I got her off the trailer at the lesson place, she was covered in sweat and shaking, even though all of the windows were open. She was terrified to be on the trailer. At every stop sign, we could feel her kicking the trailer. I had to put a "ree-ree bonnet" on her (as the people at the tack store called it). It's a protective helemt so she doesn't hurt herself when she rears. Funny thing is- she was perfectly fine when we were riding around at the new place, just afraid of the trailer.
I don't know what to do about these problems. I know practice makes perfect, but I need a way to get her on the trailer that doesn't involve stressing her out. I've thought about leaving her in the field or the outdoor ring with the trailer, but the BO isn't too happy about that idea. I'd put another horse on with her to keep her company, but she has never met my other horse before and I don't want her kicking him. He field buddy isn't mine and I have never seen his owner before, so I couldn't use him. I can understand not wanting to get on the trailer because lots of horses don't like it, but it scares me when she freaks out inside the trailer.
