Help with loping circles
So for the past month I've been working on picking up and keeping the correct lead with my gelding, he's always seemed to pick them up better on the straight away than on a circle. For the past two weeks I've been working on circles (all the gaits) at the walk and trot he's great, I can do big or small fast or slow and I throw in some figure eights as well. He keeps a nice bend and we aren't fighting and he keeps a nice even pace. When it comes to loping a circle that's when a crack in the earth appears and the devil comes up for a visit. He'll start off perfect, nice bend, smooth lope, correct lead, ect. If he starts to speed up I just gently pick up on the reins to where there is a touch of contact and he slows back down to the nice smooth lope.
Then like mid circle, right as we're passing the horse trailer he starts loping sideways, nearly runs into the horse trailer, and does a nice sliding stop where his halter is tied to the side of it. So I made him yield his hindquarters and tried again, starting at trotting circles then loping. Then he passed the trailer perfectly, did a flying lead change then did a circle and headed towards my house. I did a one-rein stop, repeated last process.
It just seems like there is always some place he wants to be, and by golly he's going to get there! If I lunge him, he's perfect (we already went through not dragging mommy around to where he wants to go) but it seems I just can't figure out how to fix this undersaddle. We go through this everyday. He knows he can get away with it.
I've found if I make him lope faster then he wont pull it, he wont even do a flying lead change, but then I have a nearly galloping horse (he takes it to the next level) and if I try and ask him to slow down after that spot then he starts going sideways to a new spot or breaks down all together. And so far the speeding up trick hasn't helped the next day.
I've thought of two other tricks, after that Im lost.
1) As soon as he starts drifting firmly (yet not really hard) pop him on the butt with the crop. He knows this as 'stop fooling around, listen to me, and get back to work'
2) As soon as I feel him start drifting do a one-rein stop, have him stand, then try again (a trainer's trick)
Those are the only things I can think of to try,
Any help would be great,
P.S. Im writing this late at night so I may not have worded something the best or used the best word to describe something. Please keep this in mind when reading and replying, thanks.
P.S.S. Not sure if it matters but, all his tack has been pro checked and fitted, he has had vet and chiro check ups. I ride him with a full-cheek snaffle, and I ride him with those short nub english spurs (because im short and its impossible to get my heels to touch him, they are used to extend my heel so I can actually touch him with my heel when it comes to yielding the hindquarters or when he ignores my leg-recommended by an experienced rider)
