It’s just like it sounds. There’s a new test out there to tell you your mixed breed’s genetic compatibility with that of a hundred-plus purebreds. Should you hanker for a reality check, go right ahead and ask your vet to look into it. She’ll Fedex a sample of serum to the lab and in a few weeks, voilá!: Fluffy’s genetically accounted for.
It might strike you as stupid but some people really gotta know…I guess. Besides the end of the age-old guessing game (which of the Heinz 57’s is he?), this new technology has a few more potentially useful qualities.
Think about the genetic diseases we vets might consider more strongly should we happen to know Fluffy’s part Akita. Or is that Malamute fur? These two breeds can be phenotypically indistinguishable (when mixed with a German shepherd, for example). But only the lab knows for sure—at least that’s what it claims.
And vets might like that—I guess. But would the expense ever make it worth our while? Ultimately, this is what tells me the benefits of this new test aren’t really geared to vets, though the test is touted in all our recent veterinary product review publications.
So here’s where the conspiracy theorist in me makes its move…marketed to vets, purportedly aimed to end all cocktail party chatter on Poopsie’s provenance… This test is aimed squarely at the forensic and regulatory crowd.
If it were only breed club registrants who had to prove their puppy mill parents were purebreds I’d be more than pleased with this advance. But, to my knowledge, it’s not something the AKC uses to screen applicants for registration—nor could it ever enforce such a thing without requiring vets or someone else to sign off on AKC paperwork (and huge expenses passed on to breeders). Perhaps an audit system?
Genetic testing tied to a microchip number might sound eerily 1984-ish, but if it keeps disreputable breeders out of business, I’d consider this an excellent step forward. It’s too bad it’s not economically feasible or I’d lay my qualms to rest right there, assuming the technology can convincingly discern a Dalmatian-cross from a Dingo-mix.
Where I’m most concerned, however, is in the potential use of such testing to effectively condemn particular dogs, especially the breed-banned pit bulls and Presa Canarios.
According to Miami-Dade County’s anti-pit bull legislation (which I despise for its short-sightedness, random enforcement, sheer ignorance and bald-faced hypocrisy), any dog that “looks” part pit can be subject to Animal Control lockup and euthanasia. (Though it’s usually enforced when only when an individual dog commits a violent or threatening act.)
In my mind, that means that Fluffy’s first and only bite, regardless of circumstances or severity, can lead straight to euthanasia if she tests positive for a partial match with pit bull genes (there might be far fewer dogs in the shelter if they tested all those, too). The ability to definitively prove breed origin through genetic testing means ordinance enforcers get more of a leg to stand on in these cases—constitutionally frail though the laws may be.
I know next to nothing about the accuracy of these tests or their current implementation but this is where my mind tends to wander when I ponder this technology. Maybe I’m just paranoid, but any test that [even theoretically] aids in the enforcement of breed-specific laws gets a big dose of my scrutiny these days.
Give me your thoughts, my well-informed readers, and clue me in. Does the AKC use these tests? How robust are they really?

I've also heard mutterings of concern over insurance companies wanting all owners of mixed-breed dogs to DNA test their dogs to ensure that they do not contain any "black-listed breed" blood. A lot of people, I think, do not have any idea that homeowners insurance companies will not insure people with certain breeds- from pit bulls and rottweilers to shar peis and chow chows.... some even list huskies. What will this kind of thing do to the owners of mixed-breed dogs, or to potential owners of mixed-breed shelter dogs?

I don't know which company you are referring to, but I have read through this particular site, http://www.metamorphixinc.com/products2a.html and they specifically DO NOT include pit bull in their breed-test list for obvious reasons. Yes AKC does use these guys, not for every single dog registered with them, but for cases where they feel it is warranted. It is an interesting concept though- I have considered having my two rescue boys tested, though I doubt it would matter one bit in their future, more out of my own curiosity.

Yeah, I don't like the concept too much. It just seems like it would make 'breed bans' so much easier in the long run... "Oh, your dog has APBT in it- gotta go!"
And I'm not a pit fan, but I realize a lot of people adore their pits and who are we to take a dog away from an adoring family?

I don't have anything constructive to add to this really.
Here in MA, Silky Haired Terriers are on the "bad dog list" because somebody got bit by one. The last Silky Haired Terrier that I came into contact with wieghed about a pound and half, so I have no idea how they compare to other breeds that are on the list, except that Pits are also a terrier. When she broke her right front leg by means of landing the wrong way when she hopped off the owners couch, the cast she had to wear weighed more than she did.
From the insurance stand point, it's just them sticking their wet, greedy noses where they don't belong, once again. It's just another way for them to make more money as if they don't make enough porfits as it is.
Greed within the pet industry seems to be making an all time high these days...

Wow. I'd not seen the list of breeds before. There are no bull & terrier breeds at all on it. Interesting. I am relieved, I admit.

Stacy--huh? I live in Massachusetts, too. When I called my insurance company to ask about getting a dog, they told me they don't care about any dog under 25 pounds, unless the <i>individual dog</i> has a record. And yes, that was this year--I got my dog just two months ago.

Hi Lis,
That's interesting. Either they have changed the rules since we bought the house or different insurance companies are telling people different things as my homeowners insurance company made it a point to stress that Silky Haired Terriers were bad dogs and that our premium would go up if we owned one.
They rolled their eyes going through the list of other breeds.. Pits, German Shepards, Rotti's, ect. Maybe the person we spoke with has issues with small terriers. LOL If that's the case, I didn't take offense and it didn't bother me as I have one of those as well.

Gah, I'm into canine genetics and practical applications of genetics in breeding -------- but this breed ID thing really smells like a WHACKED form of "Genetics for Fun and Profit". In fact I had some ongoing threads with several breeders over the past year regarding these issues.
As one breeder put it: No matter how many "breeds" so-called genetic experts claim to have on file, there is no gene for "breed". Genes code for things like hair length, color, height, ear shape - but it is a specific combination of all these things - and more - that identify a dog as a "breed".
As to identifying a "pit bull" one thing to keep in mind is that many of the genetic strings/patterns that are associated with breeds may be actually behavioral QTL microsatellites. Some may be associated with color and head shape, general morphology of the dog in question. Certain breeds have certain prevailing patterns due to the family clades they evolved from. When discussing canine genetics with associates, I call these microsats "genetic bracelets" made up of beads, a useful analogy so people can learn how a missing bead or an extra one on the bracelet can be a benefit or not. It is NOT KNOWN what each of the various microsatellites are coding for.
One breeder with Bernese and another independent with another breed I can't recall at the moment, sent samples in for prototype "breed ID" testing, I'm sure they were not alone. These were pedigreed dogs and several were show champions. Their breeds were misidentified as cobblings of other breed blends.
In another case, a friend of mine acquired an imported Turkish dog brought back from Turkey by a military person (that no importation papers turned up for) and the dog's blood sample was also submitted for the prototype breed ID testing at one company. I have copies of the results, but this (alleged) Anatolian was tested to have 53 percent of the tested genes to be in common with the Great Pyrenees.
Anatolians very likely do not decend from the Pyr, more likely they had common but extinct ancestors. The Turkish flock guardians are likely to be older in origin as flock guards than the Pyr may be.
So what you can come away with in the test is that the imported mystery dog has a pattern in his genetic 'bracelet' that had similarities to the Great Pyrs in the database.
The dog in question was young but had unmistakeable flock guardian type with curved tail, pendant ears, size, medium coated (not long haired), single rear dewclaws on both hind legs, extreme white spotted (color headed white), with a black super extension patter (black muzzle and faded ears) and most certainly had independent, protective LGD behavior. (LGD= Livestock guardian dog)
From what I have read in the lay population, people going for the idea that a genetic test can identify a principle breed are going to abuse this by taking assumptions and posing them as facts.
