Best thing you can do is to get a beta reader who is a horse person. They will gladly critique you on that point. Like any specialist, they'll get tiresomely pedantic and grimly insistent, but you can agree with everything then quietly use the bits that make sense. I worked with such a person once, and she gave me bits of information that turned out to be quite useful and which I'd likely never have sussed out on my own.
