This might be quite long and I'm new to this but I'm trying to be as descriptive as possible
I've been looking for some help for a while now.... I bought my mare about 18 months ago, she is a 10yr old Anglo Arab. When I first got her, I had no problems, she was a bit sharp but quite predictable.
She used to be kept at grazing with her younger brother, that's it. We then moved in June of this year to a yard with about 15 horses, her and her brother used to be in a field together with no other horses and she became increasingly dificult to catch. She used to gallop up the field to you despite being headshy I could always put a head collar on with no problems.
The situation now is that I would all her, she wont come, just stays in the bottom of the field resulting in me walking to her, when I get near her she threatens me with her ears back and teeth showing before walking away, It used to be that I would just have to persevere with her before she gave up and would be caught but now it can take me the best part of 2-3 housr to catch her. Once caught, she has developed a nasty habit of spinning circles on you in an agressive manner, she will again have her ears back and when you try to walk forwards, she runs in front of you to stop you from being able to take her up the field. I ended up sending her round in a lungeing affect but she bacame wise to what I was doing and didnt seem to get tired of going round in circles so she began to turn her bum on me to threaten to kick me.
I then asked for some advice from a BHS instructor who said to try and get 2 people to lead her up with 2 leadropes clipped to either side so she doesnt have the option of circling me, it worked once before she again got wise to it and just bolted forwards ripping leadropes out of your hands.
I tried a chiffney but after spending 2 hours catching her to then stand with a headcollar on and attempt to put a bit in her mouth, all she could do was head shake and despite trying for an hour, she wouldnt allow me to put it on (she is similar when bridling, headshy and shakes her head but gives in after about 5 mins).
Her brother has now gone away to be broken so she has been moved into a field with 3 other horses (2 mares and a gelding), very placid horses who have not probelms being caught, she has been in the field for about 2 months and is comfortable with her new friends, I have tried repeating the process of removing all horses so she feels lonely and wants to come in but no, she stands there and says "i'm happy to graze all day long thank you".
She has been wintered out for the last 3 years and I am wanting to stable her soon, she has been in once over night a few days ago and all went very well, she was relaxed and she isnt only brought in for riding, she can be brought in just for feed or for a brush so that she doesnt associate me with work but she is just getting worse and worse and I don't know what else to do.
Someone please help me I will try anything.
