Aussies are very popular here in the States. My SIL has two pet-quality ones that make her very happy though she has no work for them to do, they are truly just pets. The younger female is a gorgeous red merle that has stolen my heart.
I think she would be amazing at visiting patients in hospitals or nursing homes, agility, or both. And I don't think I've said that about hospital visiting about more than one other dog in my life. She's just an outstanding little girl. I told my SIL, if she ever disappears, don't come looking for her at my place ..... because this is where she will certainly be, lol!
