They are BS on humans, and BS on dogs.
They need to refine it more from what I see, and guarantee they’re not just messing with us. How are we really to know what is going on behind closed doors?
When DNA reports (NatGeo) declare German Shepherds to be basically Molosser types, I know it’s hooey that cannot be trusted.
I used to think DNA testing to identify breed was not possible.
It seems over the last decade or so testing has become more refined.
Hopefully, it will continue to be refined and increasingly accurate.
The authors do end with this cautionary summary...
“As with any new technology, breed inference is an exciting opportunity that introduces some unresolved challenges.
Many dog owners intrigued to learn more about the origins of their pet will surely appreciate having a window into which breeds contributed to the unique genetics of their mutt.
You might even earn the rights to speculate that your dog’s excellent stamina at high altitude comes from her Lhasa Apso grandparent (Li et al., 2014)!
Still, we urge owners to be cautious and remember that a variety of problems can compromise the reliability of inferences,
all the while remaining optimistic that inference will improve as reference data accrue.”
The woman who has my Portuguese Podengo Medio’s sister ran several tests on her dog, despite us knowing it was PPM, dumped by an infamous Portuguese breeder/hunter/dumpers of dogs in the deserts of CA.
The results were hysterically bad.
