Advice can change depending on your age. As a minor, you essentially have no rights. As someone who has reached the age of majority, you have rights, but only if you are the legal owner of the property.
Unfortunately, your parents are the property owners. And, apparently, your parents (unless they signed over Rusty to you upon your 18th birthday) are also the legal owners of your horse, and therefore, can do what they want with him.
These may seem like small details to you, but these details are how we can try to help you determine the best course of action for your situation.
