Gizzard! I'll crush yer barnacles! Kiss me Beard! Also, this applies to its cousin the Red Heeler, I just like saying Blue Heeler too much.

Dogs 101:

A combination of the Dingo, Dalmatian, and Collie, the Blue Heeler was bred to be a cattle dog in the new land of Australia. The Blue Heeler, or more commonly known as the Australian Cattle Dog, is a high energy and very versatile dog bred to serve and love doing it. Although tempered to withstand working out in the sun for hours, the Heeler also has a weather resistant coat to stay warm and dry.

Trivia:
The Austrailian Heeler comes in two colors, Red and Blue.
I met a Blue Heeler once in a petco.
The Blue Heeler is easily identified by its eyepatch.
The name of "Heeler" is because they are known to bit at the heels of their liveestock.
