If I read one more blog post, comment, or Angry Article™ about the horrors of purebred dogs, using photos of oddly-coiffed Chinese Cresteds or struggling-to-breathe Pugs shown in the arms of a woman who exceeds the U.S. Government Approved Body Mass Index, my head will -- yes, wait for it, readers; you know what's coming -- explode. Tiny bits of blobby gray stuff all over your monitors.
Setting aside the irony that the same people who think women not meeting the
Vogue magazine standard of the ideal woman are the ones outraged about dog breeders being too obsessed with physical perfection, there's a much bigger issue here. And before you go, "Yes, Christie, we know what it is, too. Because you've got purebred dogs and you used to breed and show them and you're one of
them, aren't you?", think again.
I'm actually a strong advocate of opening our studbooks, as well as of open genetic registries, and I think that the concept of "purebred" dogs has done both dogs and those who show and breed them a huge disservice.
But in all the hand-wringing and hair-tearing that's been inspired by discussions of the recent BBC program "
Pedigree Dogs Exposed" -- and, for that matter, in the show itself -- there's an exaggerated emphasis on photo-op-ready images of extreme breed characteristics like bracycephalic faces and short legs and long, floppy ears that drag on the ground, at the expense of something that is both worse and far less visible.
"Pedigree Dogs Exposed" holds up the wolf as an example of what dogs should be, based on how they look. But wolves who look just like the ones they used in their video clip can be
massively inbred. This is not about how dogs
look. Because although those extreme traits might annoy you personally and can cause suffering for the dogs who have them, the problem with "purebred dogs" and the closed studbooks that define them is not something you can film and see and point to -- or laugh at. The problem is something you
can't see, the genetic code of dogs who were never bred, who left no offspring: the genes we left behind.
Conformation traits that help dogs win in the show ring and give tabloid reporters and bloggers fodder for the outrage du jour are the product of selection on the part of breeders. Those observable problems that everyone is so eager to ridicule could conceivably be fixed by education and increased awareness. Lost genetic diversity causes far less fixable problems, like reduced litter sizes, reproductive failure, genetic disease, shorter life expectancies, lowered disease resistance, and greater rates of immune-mediated disease.
To put it another way, if your dogs can't reproduce because their heads are too big and their pelvises are too narrow, that can be fixed if you pluck your own head out of your own hindquarters, but fixing a problem of inbreeding depression in an entire species is a task that daunts the most ardent conservationists and scientists. It's the problem they warn us about as human development, pollution, and climate change send thousands upon thousands of species to the brink of extinction, and beyond, every year: genetic bottlenecks, inbreeding depression, loss of genetic diversity in a species and an ecology.
Genes, once lost, can't ever be recovered. Dogs who died without passing on their genetic heritage are gone forever, barring a few stray tubes of semen hanging out in a canine sperm bank somewhere. And by selecting from a small number of popular sires and focusing breeding programs on extreme conformation traits at the expense of preserving genetic diversity and health, genes are exactly what are being lost. Permanently.
So, is the canine species doomed? No. But many of our individual breeds may be "doomed," at least in the terms we in the United States and most of Europe understand the word "breed" today, breeds defined by closed studbooks.
Closed studbooks mean a registry, such as the AKC or its British equivalent, the Kennel Club, will only register dogs whose parents were registered by them as being members of that breed. It means breeders are deliberately limiting the genetic pool from which they'll select when they breed two dogs together.
Breeders do this to perpetuate the traits they desire. The best breeders do it with a thorough knowledge of a dozen or more generations of the dogs who come before the dogs they're breeding, with the assistance of whatever genetic testing is available to them, while most do it by "breeding the best to the best and hoping for the best."
The worst breeders just throw two dogs of the same breed (or with papers that claim they are) together and ship the pups off for sale before any possible negative traits can turn up, washing their hands of any suffering they're causing in those dogs or for their future owners, and then doing it all over again, all to make a few bucks.
The problem with even the "good" breeders is that the choice of dogs from which they can select in a closed studbook program is frequently so artificially constrained that they're reduced to choosing among the lesser of many evils. Few breeds, in this day of artificial insemination, overnight courier service, and jet planes, can obtain an influx of new genes from dogs in the breed's country of origin, or anywhere else. This is exacerbated by the fact that World War II created a genetic bottleneck for hundreds of breeds of dogs, as European populations dwindled or were shipped to the United States, where their lines died out or were intermingled with American dogs.
For other breeds, the situation isn't really hopeless. The "investigator" for "Pedigree Dogs Exposed" said in dire tones, "Being very inbred in and of itself has a catastrophic effect on the immune system," but that's not true. There's no magical threshold of inbreeding that in and of itself causes health problems or impaired vigor in an individual dog. Unless the dog has inherited genes for a detrimental trait, there won't be any negative effects.
But if there is a dog breed out there, of any size gene pool, that is free of negative genetic traits, I have never heard of it. Most breeds are plagued with all kinds of specific genetic diseases, and many are suffering the more generalized problems of inbreeding depression (lack of resistance to disease, reproductive problems, immune system problems, etc.). And for these breeds, nothing but new genes can save them. In the absence of an only distantly-related population somewhere else in the world, that means outcrossing.
This is something close to heresy, although it does happen. The AKC, to my surprise, just re-opened the Basenji studbook to unregistered Basenji-like dogs from certain parts of Africa. And years ago, they approved the registration of Dalmatian/Pointer crosses, as part of a project developed by the parent club to eliminate a widespread health problem in the breed. Although the parent club ended up changing its mind and asking AKC to rescind those registrations, and it's been
bogged down in club politics for years, the Dalmatian Backcross Project still continues.
There are also breeds that have within them two or more pools of dogs that rarely mingle their genes, such as breeds with a strong field/show split like the Labrador Retriever, or breeds with a strong show/pet split like the Golden Retriever, or breeds with a performance/show split like the Greyhound.
If these populations of dogs within the same breed have genes that the others lack, then it's possible to dip into those genetic pools and increase genetic diversity in your lines. You might not win in the show ring with those dogs, but you can do a lot to overcome inbreeding depression.
Unfortunately, mixing distinct gene pools within the same breed brings with it another set of problems, too. One, if you outcross among unrelated lines of the same breed, you risk eliminating the very pool of genetic diversity you were trying to preserve. Where will the dogs not descended from Ch. Popular Sire come from, if all his offspring got bred to those "unrelated" dogs in previous generations?
You also risk introducing undesired traits. Some of those are trivial and threaten nothing more than the dog's ability to win at dog shows. But some of them are far more problematic. Take the AKC greyhound.
AKC recognizes the National Greyhound Association, the racing registry, which means AKC greyhound breeders can, any time they wish, dip into that very diverse gene pool. But AKC greyhounds have a very low incidence of osteosarcoma, while NGA greyhounds have a very high incidence. While the exact role genetics play in this difference isn't known, osteo definitely has a genetic component. If you go out to NGA greys, will you increase the risk of your AKC greys developing bone cancer? Good question.
So while show breeders getting over their aversion to breeding to non-show lines within their breed might help in the short run, it's not a longterm solution.
I also don't think the solution is the extinction of the domestic dog, as PETA would like to see, nor is it returning to the days of feral dog packs and the development of a genetically diverse pariah dog population from which we can pluck alleles at will.
No, the fix for this problem is a drastic one, and it's to stop breeding within limited gene pools, stop wasting genetic diversity, support open genetic registries, and adopt the practice of pedigree cat registries and many working dog registries by allowing breeding out to foundation stock, unregistered dogs of similar type and purpose, and other breeds.
And, you know, breathing underwater and flying like a bird. Because of course, none of that will happen, at least, not anytime soon.
But we as individuals
can remove our craniums from our posteriors and stop perpetuating a broken system. The world of the purebred dog based on closed studbook breeding is not the only dog world. There are dogs out there bred to a work standard -- many stockdogs, lurchers and longdogs, lots of hunting dogs, and many sled dogs, too. Of course some people doing this type of breeding are stupid and careless, as is the case with show breeders, too, but selecting for ability -- herding, hunting, hauling -- automatically eliminates a great deal of genetic disease and freakish conformation.
And guess what? It doesn't destroy the very things we love about our heritage breeds, not their looks nor their temperaments, nor, if we begin or continue to select for performance, their abilities. The working Border Collie was developed with only a performance standard; do you ever have any doubt what the breed is when you see one? Isn't that the very definition of "breed type"?
I don't hate the show world, but I recognize its limitations and its harmful influence in ways some of my fellow dog fanciers don't. And I'm hopeful sometimes, as I see more and more breeders moving to less extreme types of dog, trying to implement and utilize genetic banking, counseling, and testing programs -- some clubs, such as the
International Silken Windhound Society, require such participation for any dog they register -- and taking a new look at outcrossing.
But I'm pessimistic, too. The chase for show wins goes on, and I've seen a world of ugliness among breeders who have a lot of ego -- and money -- invested in their dogs. People keep buying and fetishizing dogs with the worst of extremes of size and conformation. And as new breeds are developed, even with the goal of fixing some of the problems inherent in limited gene pools, they almost invariably go down the same doomed path as all the rest, closing their studbooks and pursuing AKC recognition.
So I suppose for now I'll settle for suggesting we try something simple and achievable. Stop whining about doggie hair-dos and conformation extremes, and focus on the scientific and medical problems caused by closed studbooks. Stop perpetuating junk science about 'poo dogs and their "hybrid vigor"... excuse me, "hybred" vigor... and try digging into the real science of inbreeding depression, genetic bottlenecks, and popular sire syndrome.
Junk science is like junk food: it goes down easy, but it's not good for you. "Pedigree Dogs Exposed" plays on our love of dogs to whip up outrage over micro-tiny dogs with bulging eyes, titillates us with gasps of horror at brother-sister and father-daughter breedings, and uses images and descriptions of snooty elitist 19th century British upper class dog shows to imply that the people who get up at 4 AM every weekend to drive a hundred miles in their mini-van to trot a dog around the ring and then go through the drive-thru and eat a burger while driving home are the close relatives of Her Majesty the Queen.
Take this exchange between our intrepid "investigator" and a representative of Britain's Kennel Club, where she asks him whether he thinks mother-son breedings cause health problems in their offspring. He, quite correctly, replies that it depends on the mother and son.
Her response? "Do you have children? Do you have a daughter? Would you have a baby with her?"
He replies, with irritation far milder than mine, "That's a totally different issue."
"It's the same issue," she insists.
Of course it's not the same issue. The issue is degree of inbreeding, not human incest taboos. You can mate two dogs who aren't siblings, parent-offspring, or even first cousins and have a greater degree of inbreeding than in some full-sib matings. But that's not going to make all your viewers go, "Gross!" is it?
That's not even junk science, it's just tabloid sensationalism. So is using a photo of a Komondor -- a wolf-sized working dog who is among the healthiest of breeds -- in a segment on extremes of conformation that lead to health problems. Why? I guess because they're shown in a corded coat that the producers of the show found mockable. Well, newsflash: the hair-do isn't a genetic trait.
Breeders use junk science to justify their actions, too, of course. A few who were interviewed expressed outrage at the idea that a dog might be banned from the show ring for having a genetic health defect, but then they turn around and fight like the devil to preserve their right to disqualify dogs from showing for possessing a cosmetic genetic defect, like a ridgeless Ridgeback. The problem is, genetic traits are genetic traits, and having one set of rules for cosmetic traits and another for health traits is indefensible scientifically.
So, stop already. Both sides, break your junk science habit.
And oh yeah: open the studbooks. It won't hurt half as much as you think it will.
