As Rowdy dogs said, they often test animals to prove who the parents are. Especially in the bully breeds, often the pups are dna tested to prove parentage, mom and dad really are the parents of that puppy. But it is not at all testing the breed of the dogs, just proving parentage.
I have almost zero (you just gotta have a little though lol) faith in breed dna testing, but I'd love to have the money to blow just to get that good laugh. I would test my supposedly border collie/rottweiler/labrador and my german shepherd, whose parents, grandparents, great grandparents and beyond I have knows since puppies and grew up with. I'd love to see those dna results haha.

With Spirit she came back a combination of Saluki, Scottish Terrier, Border Collie, Basset Hound, GSD and a couple others I don't recall. She is a 40 pound Sheltie looking mixed breed, but Sheltie never showed up!

LOL I didn't think you meant other species! I was just a little confused because the specific types of testing I said were valid (verifying parentage and testing for genetic disease) had nothing at all to do with breeds, so there is no way for those tests to "come back" with any mix of breeds. Basically, my point was that so-called breed markers are mostly a bunch of BS at this point, but that genetic testing does have other valid uses.

I was thinking you might have misunderstood what I was saying about the Arabians, where it's nothing about any specific Arabian breed markers, but rather a verification that the horse is in fact the offspring of two registered Arabians. At this point, those registered Arabians may also be DNA-verified offspring of two other Arabians, or they may just be DNA-typed. Basically, when the program was adopted, registered breeding horses had DNA samples taken but they were known to be purebred Arabians because...well, they were known to be purebred Arabians. It has nothing to do with the DNA identifying them as such, just standard record keeping.*

Either that, or that you might have misunderstood the genetic disease thing, but the thing is that most genetic diseases in dogs aren't specific to one breed. So multiple breeds could have the genes for a given disease like hip/elbow dysplasia, degenerative myelopathy, etc. Actually, this is one area where dog breeding seems to diverge from horse breeding (which is where my experience lies, in case you can't tell by my equine examples ), because in horses many genetic diseases are quite breed-specific (for example, SCID in Arabians, HERDA and HYPP in Quarter Horses). In dogs, you see many of the same diseases across several breeds. I'm going to have to look into why that is, because it's interesting and I just realized it (and it's also very possible that I'm missing something here). And while breed-specific genetic diseases might give you a clue about the breeds involved (for example, if a horse has HERDA or HYPP, he's almost certainly got at least some Quarter Horse in him), it can't say for sure what breed(s) the horse comes from. If he's HYPP N/H (in other words, got it from one parent, didn't from the other), all that tells you is that one parent probably had some Quarter Horse in him/her somewhere. It could range to a purebred Quarter Horse whose other parent just came from lines that didn't have HYPP or maybe did but the parent was lucky enough to not inherit it, to a horse with just a bit of Quarter Horse blood but whose QH parent was unlucky enough to inherit HYPP and pass it on to the foal. Either way, you'd get an N/H result. And there are plenty of N/N horses, so the absence of HYPP doesn't prove anything, either.

Anyway, a huge oversimplification, various genetic diseases/inheritances work differently (genetics is very complex), etc. but it hopefully gives an idea of why you can't really identify breeds through DNA testing.

*Incidentally, there was a scandal not too long ago but pre-DNA-testing where a non-Arabian stallion sired a lot of successful and supposedly purebred Arabians because of fraud on the part of the stallion owners and trainers. While the fraud was discovered and all the offspring lost their registration, in theory that could have happened in other instances and not been detected. In that case, the DNA test would not reveal anything, because it would still just show that the foal is the offspring of those 2 parents. If one of those parents had, say, a Saddlebred parent prior to DNA testing, no one would know and there would be no way to prove it. However, DNA testing does help prevent another scandal of that sort, because it would be nearly impossible to fake (basically, you'd have to plan the scandal from the moment you registered the young foal, since DNA samples are required with registration...and with the difficulty of predicting a superstar stallion, it's not really practical), and if it was pulled off, it would be very easy to prove.

So apparently I take too long to edit late at night... In my paragraph about genetic disease, the last sentence was meant to read, "And there are plenty of purebred N/N Quarter Horses, so the absence of HYPP doesn't prove anything, either." (changes in italics)

Hope that makes more sense.

Bumping this old thread.

Has anyone had any more recent results? I am thinking of getting a DNA test for High Jinks. I've had enough dog people tell me they see no Malinois at all in him (which is interesting because I get quite a few NON-dog people ask me if he's a "Belgian" LOL!)

"That's the Terrier in him", she'd say when I remarked about the coarse wiry hairs in his coat, and "that's the Retriever in him" when I talked about the soft cottony hairs in his coat.

Here's the dog... his matting was so extensive that I had to peel it off little by little with the clippers, and it came off in one big piece. The owner was clueless about that, too.

That must be the Komondor in him

Belgian Shepherds, German Shepherds and Dutch Shepherds are all closely related in their origin. It might be impossible to truly differentiate those breeds with DNA.

Oh- good point! I didn't consider that. I just checked Wisdom Panel and it does list all the Belgians independent of GSDs. http://www.wisdompanel.com/breed_cou...eeds_detected/
