The lesson horse that I normally ride (actually my 'lessons' are more like renting a horse for an hour because I've advanced enough to where my instructor has taught me everything she can), Goldie, when I'm grooming her, she'll paw. She does the same thing when we hose her down (we don't hose during the winter, of course). I always give a pop on the lead rope when she does that, but when I go back to grooming, she keeps doing it.
I won't be able to ride her today, she is out with an ankle injury :( I don't know what happened to her, all I know is she has an ankle injury, but I'll ask when I go to the barn.
So what can I do to keep her from pawing in the stall? I don't know if it happens when other kids are grooming her, I think they might be putting her in the crossties? Just thinking about it now, I might start putting her in the crossties to groom.
