What would you do with a greenie?

Get everything solid at the trot and do lots of walk-trot transitions. Try circles, serpentines, and bending to get her supple. If she's being lazy and won't step into a trot, you can tap her with a crop to get her attention, or even pop your boot. If you don't like hitting her, you could probably use a soft nerf bat on her if you could find one, or flick your split reins if you ride western. Voice commands are a huge help, too.

When you're ready to canter, push her into a nice trot, give her a squeeze behimf the girth, and back up your aid with a tap if you have to. Let her go a couple strides, then bring her down to a walk as a reward.

I'm actually working on one of my horses right now too!!!! (very green). Anyway, just to start off...TRAINING TAKES FOREVER well...not forever, but it takes a little while for things to finally click in horses heads! My horse right now (dixie) has the same problem with the trot transition as well. What I do, is close my leg first. If there's no reaction then nudge a little bit. And if there's no reaction and it's quite clear of what you're asking then give her a good kick. Because i you've politely asked her first, then she lost her chances (two of them actually) and now she's going to get kicked. Over time it ill click, but don't give up. And for the canter...Dixie JUST got it the other day but. Make it a TOTALLY different aid then all of the others. What I did at first, was push my outside leg way back and used my spur to bump her once. While your doing this make sure your inside leg holds her on the rail though. You want the canter aid to be like none of the others. After I used this way ( it also helps to drop your stirrup) a couple of times, Dixie started bucking to get the canter. So I picked up my stirrup and barely nudged her and she got it. They will let you know when it is too much and they understand . For the confidence, rub plastic bags alll over her, try walking her over tarps, and through puddles .(basically more of the trail stuff! well I hope this helps!!!!!:)

Ja-maken me blush<3

do a lot of lungeing work with her. that helps her form the basics, and to learn to get the right lead when you canter. even if she is green, she'll learn the cues for cantering. tip her nose to the wall slightly, and slide your outside leg back behind the girth (don't over do it). then, squeeze with the outside and keep your inside leg on, and if she doesn't get it, a small kick.

good luck!
