Hello & welcome!
I am sure with some time,love,patience Lacey will do wonderful. I do have to also agree with everyone about the Thundershirt.
We have one for Mia,our blind & deaf double merle. It has been the most wonderful thing for her. Although now at nearly 19 months old,Mia has done remarkable with out the short on,but we do still use it if we are going places,or meeting new people.
Google for "Thundershirt for dogs" and you will find the official website.
