No disagreement on viability of the offspring and their subsequent ability to mate further down, only a disagreement about percentage between single digit up to “half” in the current breed (as it exists in the USA). I believe it’s notably diluted from the original cross for reasons I stated in my other reply, but I’m curious about my red since she’s considerably more dingo-esque than my blue.

Anecdotal evidence is the best evidence, right?

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.

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.
