My horse will only longe one way. No matter how hard I try, he doesn't understand hoe to longe to the right. I don't have a round pen or any of those resourses. Does anyone h\have any ideas how to get him to longe the other way?
If you have help available, have someone hold his halter and lead him around the circle to the right while you are standing in the standard lunge position.
If you are by yourself you can do the same thing. Holding the lunge line so it can pay out, lead the horse to the right, of get the horse to walk next to you without holding the halter, and slowly let out the lunge line while maintaining the walk and staying in the correct position you would be in to lunge...behind the shoulder. It may not happen immediately..the horse will probably stop, maybe turn.
If you have a small enough paddock you can try free lunging, similar to round penning as the lunge line is not attached, concentrating on keeping the horse going to the right as much as you can...when the horse does lunge to the right give a LOT of praise.
Make sure you, yourself are not blocking him from moving forward...
At first don't worry about the "circle" just get his feet moving the direction you want... Once he will go forward, start asking for the circle by leading with your right shoulder (if he is going to the right). Actively be thinking "pull my right shoulder back" and make sure your eyes are looking where you WANT him to be, not at him.
Most people are asymetrical in posture... This means we, unconciously, can be blocking our horse, be it from the ground or in the saddle and the horse will refuse to move the way we want.
Combined with that, most horses are asymetrical too... If you and the horse have the same weak side it will be a huge challenge to correct things... But with more focus on yourself you can help your horse change too.
Does he yield to pressure, lead & drive from that side well? If not, that's where I'd start, in that order. I look upon 'driving' a horse as the remote form of direct pressure & manipulating their movement, and lunging as doing the same at greater distances. So start with the easy stuff, teach him the basic principles & as he masters those, gradually teach him 'harder' stuff.
