Hard to slow done. My two horses love to go faster. I actually looked for one like that. They will walk, but unless made to they love to fast gait (walker) and trot (Appaloosa). Walking isn't a speed they agree on with the rider, but will do. The walker you need to let him get a little energy out first. We ride our trails fast paced with these two, but if others are with us we slow down. I can get them both to walk, while others can't. Neesless to say I just sold two horses because they where slow pokes.
