I'm trying to figure out what happen in the head of my horse today.
I have a 7 years Gidran stallion that have a problem with people riding him. He was bought in December from a state ruled stud farm. From December until January we had no problem with him. We were able to ride him without any problem. At the end of January I went in vacation and I was away from the horse for almost a month.
When I came back I discover the horse was un-rideble. I suspect that the guy who ride him (in order to train him to be a trail horse) was putting to much pressure in the reins even when the horse was walking.
I started to d Join up with the horse 5 days ago. I was pretty much unsuccessful untill today when we did really well. He started to follow me and everything seemed to be ok. I gave him a 10 minute break and I started to work with him on his riding problem. I did not use any kind of violence, not even verbal. After I finished and when I was happy with the improvements he made, I gave him another 5 minutes break.
I just wanted to finish our "meeting" in a positive note so I wanted to see if he will still follow me. All I did was looking in his eyes and approaching him more aggressive when he was not looking at me and get away, with my eyes down and my shoulder at 45 degrees when he was looking at me. He followed me for some time and when he was losing the attention I used to look in his eyes and approach him. We did this several times and the last time I looked him in the eyes and approached him, I turned away when he moved his head in my direction but by my surprise, he came to me and bite me from my back pretty hard. It was the first time he bite me and I was even more surprised he did this after a (what I thing it was) successful join-up.
Why do you think he did this and what should I do?
Sorry for my long post and for my pretty bad English. Thanks for your help!
