Hello, I need help! I am currently working with a horse who has not been worked or messed with much of her life (She is five or so now). My biggest problem is when I am doing groundwork with her and try to ask her to ask her to move away from pressure, like do a turn on hindquarters, she pins her ears and will move but she clearly doesn’t like it. This sometimes will turn into her trying to bite my hand or kick me.
She gets most aggressive when I try to send her away on the lunge. She will pin her ears and won’t move. Then, if I keep asking or press harder she will bare her teeth at me and turn towards me or may try to kick me. There are rare occasions I can get her to lunge around me but she only walks and if I ask her to trot she will turn in towards me with pinned ears and try to bite me, sometimes kick me.
This sounds dangerous - what area are you in please?
I realize I am a little late into this but your horse's behaviour reminds me of mine. The cause of his bad temper in similar situations was due to pain in his back that stemmed from a damaged (hind) knee. The injury went as far back as his third year but the diagnosis then was a nerve damage, which had healed. Unfortunately, it left a morass of damage behind that took (too long) time to find.
Therefor I would strongly suggest a very thorough checkup externally and internally as mares can have uterus problems as well, before you demand more of your horse. I can assure you she is highly likely to turn worse if you don't heed her now.
Your situation with your buckskin gelding seems like a handfull and dangerous, since the horse already knocked your husband unconcious! Some horses should be in the hands of professionals, at least when trying to change their behavior.
So PLEASE search for a Certified Instructor in Monty's methods where you live and don't experiment with a difficult horse like this! He'll have a long story to tell and it needs a experienced trainer to read the storiy and help your horse.
Stay safe and keep in touch!
