Australian Cattle Dogs truly have a beautiful history. From a diverse genetic line including Dalmatians, Dingos, Blue Merle Highland Collies and the Black and Tan Kelpie, Australian Cattle Dogs were bred to control the number of free ranging cattle in Australia during its early colonization.
Today, they are a very common family dog in various countries around the world, such as The United States of America, European countries and Australia. Their nature is very calm and collected, yet protective with a stamina that lasts from sunup until sundown (which comes from the Dingo). So while they make great family pets, many Australian Cattle Dog owners try to squeeze this big job focused dog into a smaller and quieter lifestyle than it needs.
This is where I see things go awry. This dog can literally (and should) work all day at a focused job such as herding cattle. If not given the proper job on a daily basis, you may notice that your Australian Cattle Dog has suddenly resorted to herding your kids or anything else that moves. They are one of the most intelligent dogs, and this is why brain games can go a long way for the off hours that they aren't able to be outdoors.
The Australian Cattle Dog is not a good couch potato or "stay at home" dog, because they have such a high working drive. They make fabulous farming companions, but are not an ideal house pet for the family that doesn't do much outdoor activity or is unable to commit to giving this dog a proper daily job.
