I've been working with my mare on lunching for a while. In the beginning of this summer I was finally able to get her to canter on the lunge line. I usually lunge her every other day or so, mostly walk trot with a little cantering. The past few days though, when I ask her to canter, she will go around a few circles ( at a canter) Ans then all the sudden stop and backup slowly a good ten feet while looking at me - licking and chewing. When I point and ask for her to start our circle again, she just backs up more and moves away from me.
I do not have a round pen, which is probably part of my issue- but she has never done this before until recently. And it's only when we canter to the right ( Clockwise) If we go to the left (counter clockwise) she's fine and will canter like it's not a problem.
Any ideas on why she is doing this?? It's becoming very frustrating and I am not sure how to correct it
