Deb, this is so wonderful! I know your life will be so enriched by having this animal. Without my cats, I fear to think what might have happened to me. Animals can hold us steady.
I just wanted to ask about holding her. This, because I have a friend who is blind and has a Service Dog. He has said that because he is a working dog, he doesn't get very affectionate physically with him. But he did tell me (this was quite a while ago) that training the dog involved letting the dog know how to behave when "on duty" and when he was off-duty, too.
I know you will do just the right things in training Heart. And she will train you, too!
I can't imagine your happiness. We all are rejoicing with you.
Shalom
