Hey everyone, i'm pretty much out of ideas so any and everything is appreciated. I just bought a 5 year old appendix mare and rode her for a few months while going to school at a different barn before deciding to buy her and bring her back to my home barn. She was a dream to work around and ride while she was at the her original barn but has turned into a completely different horse since we've had her at home. She's been here for almost two weeks now.
My problem: the first time that I got on her since having her home she was dancing all over after I mounted and was refusing to walk around the ring without putting up a big fight. So I put her on the lunge line and worked her for a good 15-20 mins at the trot and canter before attempting to mount again. She was mediocre at best for the rest of our workout. The next day I got onto her and before both my feet were in the stirrups she reared throwing me off. I did the same thing as the day before and lunged her for a few short intervals all while getting on after lunging and getting off when she would refuse to move forward and sending her out to work on the lunge line. Long story short she has done the same thing to me today and I tried the lunge line thinking that maybe she would realize that refusing to move forward is just going to create more work for herself. I've tried just about everything and i'm running out of ideas.
If anybody has any tips on how to help they are much appreciated...sorry for the length of the post
