Jack is a 10 year old thoroughbred that is 16.2 hands in your pocket part dog personally he will  be the first to greet you at the gate. He never raced on the track and is not registered. The person I got him from did nothing with him and he sat in a field for 7 years I got him three years ago and started him under saddle and put all the fundamentals on him. He will walk trot canter pick up all leads has a nice stop on him. Has had a few trail rides seen cartel, goats and handle it fine. He is more go then woah.
