**Before we get into it I do want to make a disclaimer: the information provided will be general information. Breeding, individuality and experience may change how a dog reacts to certain situations. This does mean the information provided here is incorrect. The exception does not negate the rule. I have always believed that you should train the dog in front of you not how the dog should be trained because they are x, y ,z, but it is important to have an understanding and a baseline to work off of.** Something I hear a lot when listening to dog owners talk about their dogs and wildlife (or domesticated animals such as cats) is that their dog hates them. “My dog hates squirrels”. “My dog hates rabbits”. “My dog hates cats”. When in fact that is not what is happening at all. First let’s define predation and aggression: - Predation: instinctive, biological, behavior to chase, capture and sometimes kill. This is established based on their ancestral hunting instincts. - Aggression: behavior intended to oppose or defend against a threat but does not kill for food necessarily Something to consider when trying to figure out the difference between the two are what is the purpose, behavioral sequence, target perception, outcome and emotional state of the dog. Understanding the difference of these things will help tremendously on identifying what is going on in your dog’s mind and how you can properly address it. So, in the world of predation the purpose would be to obtain food which is key for survival. This drive to try again and again even when the dog fails is so engrained in their DNA that just providing your dog with good quality food at home is not enough. Your dog will not put two and two together that they don’t need to hunt after an interesting critter because you feed them good food at home. Whereas with aggression the purpose isn’t survival it is to eliminate competition or a perceived threat. This could be a threat to their territory, themselves or their pack.

The Australian Cattle Dog aka Heelers have also been called Queensland Heeler, Halls Heeler, Blue Heeler and Red Heeler. The Australian Cattle Dog earned their other name, Heeler, due to moving cattle by nipping at their heels. This trait is present due to their dingo ancestry. What breeds were used to make up the Australian Cattle Dog is up for debate due to the records being disposed of but it is thought that some breeds include: Blue Collies, Kelpie, Bull Terrier and the Dalmatian (although the Dalmatian has been questioned). How a wild dog would breed with a domesticated dog is not entirely known but a popular theory is that a litter of Dingo puppies were abandoned and raised domestically and from there was able to breed with domesticated dogs. While the theory is a consideration it is in fact a man named Thomas Hall who is credited for developing the breed. It is said that Hall, a cattle rancher, imported dogs from the United Kingdom, such as the blue-speckled Highland Collie, other sources say bob-tailed drover dogs with a blue coat, and crossbred them with the wild Dingo. This crossbreeding created a dog that was sturdy, tough, robust, active and could handle the Australian Outback but also work alongside their human. It was in 1825 that Hall was first successful in breeding this new breed of cattle dog. Through continual and selective breeding, he had developed an extremely handy cattle dog by 1832. It wasn’t until after his death is 1870 that his dogs would become available to other people aside from friends and family. This is also where the breeding records of how the cattle dog came to be is lost to history due to the details of his breeding program being thrown away. Sometime between 1845 and 1855 another type of Heeler was developed. These were known as Timmins’ Biter and were leaner than Hall’s Heelers, were blue and had stumpy tails. Cattle dogs were also said to be mixed with Kelpie which helped further develop their herding abilities and changes to their markings.
