Writing for the Kentucky Horse Council, Tammy Platt gives advice for beginning riders: A horse with little or no ground manners presents a set of challenges that may at first seem insurmountable. While there are obvious problems with this type of behavior, there are some underlying issues that can make training more difficult as well.
There are a few fundamentals you can teach a horse, no matter what your training style, that will help make those first few rides go as smoothly as possible. These essentials include 1) how to stand tied up, 2) how to move away from pressure, 3) how to give to a bit or side-pull, and 4) overall basic ground manners (i.e. your space vs. their space).
