He has always been like a big teddy bear. Very loving, very easy to handle, could do anything with him. He'd come right up to me in the pasture, I could easily halter and lead him, easily pick his hooves, he LOVED being groomed, etc. Was always great for the farrier and the vet. I used to be able to just go out into the pasture with a hoof pick and do his hooves right there, no lead rope, nothing. Suddenly a few months ago it changed. It started with him not letting me pick up his hind feet... he kicked and ran. The next time the farrier came he stood there shaking the entire time and kicked and tried to bolt when she tried to lift his hind hoof. She ended up having to lift it with a soft rope and hold it until he calmed down so that she could trim it. Then he did the same thing with the other side. And he's been like that ever since. Now he is like that with his front feet as well. And now he has started running when he sees a halter or lead rope. He bucks and hauls butt. If I start brushing one of the other horses he will come up and act like his old self, he will bump me with his nose and want me to brush and scratch him. But it's only when he comes to me. If I try to go to him he hauls butt.
He has absolutely no reason to be afraid of me. He's never been hit, never been hurt, and he will come up to ME in the pasture for scratches. So I'm not sure that it's a fear thing. And the fact that it's getting worse makes me think that it's an attitude thing... like he's getting away with it, so he's seeing what else he can get away with. But 10 is a little old to just be starting this, out of nowhere... Idk. I don't really know what to do with him.
