You are all here to learn about buying a horse. The top thing you should do first is learn about them. Do you know the care, like grooming, feeding, and exercise. No one can just learn from reading online. Volunteer at a local horse shelter, and you will most likely learn everything there is to know about them. Now, do you know how to ride? It would be a good idea to take a couple of riding lessons. Take caution though. Don't go behind a horse, and always wear a helemt.
