THE AUSTRALIAN CATTLE DOG WAS FIRST KNOWN AS THE AUSTRALIAN HEELER, ALTHOUGH IT IS STILL CALLED THE BLUE OR QUEENSLAND HEELER TODAY.
The Australian Cattle Dog SHOULD have an intact tail. There are a LOT of misinformed ranchers who still insist on docking the tail of these dogs and it is a GREAT disservice to the dog. This breed uses its tail as a rudder when making the sharp turns necessary during herding or during daily activities such as frisbee and tennis ball chasing.
