What happened to my tiny chunk ball? Where did this elegant beast come from? What happened?
Have you already done a breed overview of the Queensland Heeler/Blue Heeler? We had them growing up, and I'm quite fond of them, but we never learned a lot about them in my animal science classes as a breed (they're not super common in the Midwest). We lost one at age ~11 due to heart cancer, but I don't know if that's common for the breed or just bad luck.
