My horse is getting abused!

Well she may have taught him that seeing her = work. Horses are smart, and they will even avoid their owners if all they do is work and no play. Same concept as if they see a bucket and associate it with grain and eating. Then every bucket they see they think had food inside.

Horses are not only smart, they have a keen sense of how to act to get you to let them off the hook so to speak. My stallion will be an absolute TURD and then he'll do something that makes me laugh. He has figured out that if I laugh I can't kill him. I end up telling him he's funny and gosh, look at that, I'm out of time to make him work and have to move on to the next horse. He doesn't get me as often now that he's 5 and I've had him his whole life, but every now and then....Yup, suckers me right in and he's out of work, off the hook. When he was a baby, he was so adorable it's a wonder he ever got halter broke.

What does the whip she is holding look like? You said she brought it out and told you to use it, could you post a link to something similar?

Editing, sorry for the double post - I don't know how to delete :(

Chevy, you can trust what your horse is telling you, as well as your instincts. I hope you can find a different place asap.

Agree with DRichmond. It does sound fishy to me & even if you're unsure, I definitely wouldn't discount it. Have you asked the BO about it? If you can't move him immediately I would request that she doesn't deal with him again, in any manner. If she has a problem with that, I'd be inclined to remind her that the law has problems with people taking liberties with other people's animals too.

Point out the welts/wounds & ask the BO point blank- "What the hell are these from?"
The reason the other barns are full is because they are better than where you are. Get on a waiting list & until you find a place do as Loosie suggested.
Pictures would help to ID how the wounds got there.
