    It depends if their progeny can reproduce. A male donkey and a female horse can make a mule but mules are sterile.

        They are not, it’s just some breed representation thing, and they certainly look more dingoey than a Jack Russel, but at least in the United States, it’s likely to be trace amounts. Source, I own two, but admittedly neither have had any sort of genetic test so I guess my hearsay is as good as yours…I should find out, I honestly wouldn’t be surprised if they had up to a quarter dingo somehow.

          No I just mean in general, the Australian cattle dog was originally created by crossing herding breeds (mostly speckled collies) with the native dingo. The collies couldn’t handle the heat so they introduced a breed that was capable of doing so.

          If you do a genetics test it’ll just show them as being “Australian cattle dog” cause that’s what the genetic markers are identified as now.

            Right, but they’re no longer half dingo after the multitude of generations has passed in whichever pedigree, because for whichever innate temperament traits you might desire, along with the inability to selectively breed for physical ones with a wild dog, you wouldn’t take a second generation heeler and cross a dingo back in just to keep the percentage up. I don’t honestly know the whole history but it’s conceivable that enough of the original breed starters contained sufficient “dingo” to keep the content up.

            I thought I had read that one of the various tests…wisdom panel maybe…was providing results indicating wild crosses, including dingo. My thinking was that any significant percentage would show, but time will tell, since we have whichever brand that was, and just need to collect and run the sample.

      Not that simple. Brown bears and polar bears produce fertile offspring, as do bison and cattle, and the false killer whale with a bottlenose dolphin. (Far from an exhaustive list)

      It’s generally a useful definition but it isn’t a “rule”.
