They say that these great dogs have descended from the wild Australian Dingo dog.
Most Heelers are born with a white coat. And the white patch on the head is called a Bently Mark, which is supposedly named after a breeder called Tomas Bently.
The oldest living Blue Heeler was Bluey, he lived to be the ripe old age of 29 years and five months. What a lad!
