I know there are a million threads on lunging already, but I can't seem to find any information that can help me. My horse knows how to lunge, she knows how to stay out on a circle of any size, balance herself, and all the cues for w/t/c and of course whoa. She's perfect, until we get out past about half of the lunge line. Then she gets testy. She rushes her trot and canter, she gets hot and won't stay in the walk for more than a few steps. She takes half a circle of not a full two or more to come back down to a walk, or even a trot some days, even when I make the circle tiny (like basically shoulder to shoulder I'm getting dizzy tiny). We've done all kinds of ground work and are keeping up on it, but I can tell that she's just going through the motions, there's just enough hesitation that it seems she's constantly checking if she really has to do anything I say. I'm really not sure what to do with her at this point, any advice would be appreciated. P.S. I do have a new trainer, who is having the same issues if not worse with her, although tends to work through it faster.
