Rescued dogs are among the most loyal you can ever own and so far it seems like you're giving her a great life.
Just make sure she can't escape through a hole in your garden or front porch. A lot of people seem to understimate the jumping and curious nature of yorkies, since they ignore that this breed was created to hunt mice and rats, so they will try to get through any holes no matter if it seems too small for them. This is why training them to "stop" is so important.
