My horse is a small Quarab, therefore he has very short strides as well. I have my trainer, mom, and friends always ask me what lead im on. I concentrate on the way my hips are moving, they should be moving toward the inside. Sometimes I'm right and sometimes im not, but I'm getting better at it. Don't have someone tell you your lead because then you'll learn to depend on someone else knowing for you. Just do what I do and start to get more familier with her canter
