Brought him to my instructors barn, and he's been a little spooky here and there, but nothing that we couldn't work through. But, when I'm riding him, sometimes, he does what I like to call the worm. He will not stay against the rail, he doesn't listen to my leg at all, and for example I will ask him for a trot and he will, but he will twist his neck, and do this worm action sideways. It is way worse on his right lead, and trying to get him into a lope that direction is very difficult. And sometimes keeping him at a lope is difficult! I have started lunging him a few times a week, I am not overly familiar with groundwork techniques, deffinitly need to learn. But obviously I am doing something wrong, and some days are worse than others!
Thanks for any advice :)
