I used to have so many people ask about my Aussie Terrier Poochie too.  They'd insist she must've been a silky terrier x maltese or something weird and when I informed them she was a purebred I'd get the "are you sure?" look!  
Lately I've been seeing Newfoundlands and a Weimaraner who's about 8.  I don't know if they are considered "rare" but they are from a location, which seems to have a lot of rescue dogs, mixed breeds and staffies. 
Oh and there's a lady down the street who owns a black Scottish Terrier and every winter she walks him in his gorgeous red tartan coat.  So damn adorable!
