Mini Aussies are so new that there isn't good data on it, but it looks like they're about the same as normal aussies. Worry about her enough to get annual geriatric vet visits, but beyond that she could until she's 18! I know an aussie that lived to be 18, and I know a full size German Shepherd that lived to 18, too. It's a crap shoot when it comes to individual dogs. I know a female 2.5 year old berner that just died because she ate a sock and bloated.
