what is green breaking a horse
A green horse (or rider, for that matter) is a horse that has little or no training. Usually a horse is referred to as green after it's saddle broke, otherwise it's considered unbroke, halter broke, etc. When it comes to showing, a green horse is often a horse that has had less than 1 to 2 years of showing experience. Other times it's a horse with less than 2 years of under saddle training.
