The Australian Cattle Dog (ACD), otherwise known as a Cattle Dog, or Heeler, was originally developed in Australia to herd cattle over especially rough terrain.

They are frequently referred to as Red or Blue Heelers because of their distinctive coat markings and coloring. Both coat colors are mottled and speckled, but Blue Heelers have a white coat with black hair causing the fur to appear blue, while Red Heelers have a white coat with brown hair which causes their fur to look red.

As with dogs from other working breeds, the Australian Cattle Dog is energetic, intelligent, and independent streak. They respond to structured training, and have a need to be challenged. This is a dog that needs a job, otherwise various bad behaviors will present themselves.

Australian Cattle Dogs were originally bred to herd by biting at the heels of their herd, and are known to nip running children or their owners when they want them to move to a particular place. Due to their high energy and drive to work, they are not suitable family/house dogs, and instead are best used as a working dog.
