Our trail riding horses get to spend their entire lives on our farm. They are all trained on the property, work on the property, and eventually retire on the property. They are a part of the family to us and are treated as such. This kind of lifestyle helps ensure the environment in which the horses are raised and therefore helps with predictability of the manner in which they behave. The calmer the surroundings in which an animal has been raised, the calmer it's interaction with humans.
