About a month ago, I got a 20 year old shire mix mare from my friend's cousin's wife's brother (I think that's how it went...). She was in pretty bad shape, so we put her in the pasture for a while.
After a while, I was going to take her out for a little bonding time. She was very friendly, but wouldn't let me put her halter on. After I finally got it on, I tried to lead her, but she refused completely. I tried every trick I knew, and finally got her to go a bit, but she throws her head in the air, pulls back when tied, and won't go any faster than a walk. (Which is a real problem when the vet tried to check her for lameness.)
Can anyone offer me some advice?
