Do breeders need to change?

The face of breeding, as I’ve known it, has changed considerably since I first joined the ranks of Gordon Setter breeders in the 70’s. So much more information is readily available, resources for every question can be found at the touch of a keyboard, cross-country breeding is accomplished without shuffling the bitch off to the airport, and the availability of genetic tests is growing quickly to theoretically help us breed healthier dogs. But are we, the breeders, utilizing the results of those tests with a consciousness that will improve the overall health of the breed or could misguided perception and dwindling numbers cause the downfall of the breed instead?

I just read, and then reread an article written by a Corgi breeder Joanna Kimball – “How We Must Change as Breeders and Why – A Football Field of Dogs”  published in Best In Show Daily (point and click on the bold title to link to the article). Joanna raised some valid points regarding breeding that I believe bear discussion among Gordon Setter breeders. I hope you’ll join me here in considering some of those points and then by sharing your own perceptions, agreements or disagreements as they be.

First the assumption that as a breeder we should all agree that only a very few dogs should ever be bred – is this true? The breeder’s thought process as Joanna wrote is “I should be as picky as possible, first health-test everybody, prove that each dog is healthy, make sure that only the ones who are incredibly high-quality in terms of conformation and show success are allowed to breed. I should build the next ten thousand dogs from the most elite pool of this one.” That’s the conventional wisdom, the way “good breeders” do everything, right?

In fact, Joanna says we should bear in mind thatEVERY DOG WHO IS REMOVED FROM THE POPULATION HURTS THAT POPULATION.” To maintain health in any breed we need to understand the need for genetic variation, and to retain genetic variation we need to be breeding from many lines, to many sires not only the one or two most popular sires and so on.

I often want to go back to when I was younger, just starting out, and in this case I’m talking about the days when breeding wasn’t a four letter word and the propaganda of animal rights activists hadn’t put us all under their spell. The spell that makes breeders feel self-righteous for eliminating as many dogs as we can from the breeding pool because breeding is, after all, a very bad word. As the battery of DNA tests for genetic disorders continues to rise breeders are feeling satisfied as we believe we are gaining ground on health issues. But, should we also be considering that we might be losing ground on genetic diversity as we eliminate more and more dogs from the breeding pool with those tests?

Joanna states in another  point “SINCE EVERY DOG THAT IS REMOVED FROM THE POPULATION HURTS THE POPULATION, WE MUST REMOVE ONLY THOSE WHOSE PRESENCE WOULD HURT IT EVEN MORE.” To me this is like saying “Don’t throw the baby out with the bath water”. A common sense approach would include knowing what health condition could cause the death of our Gordon Setters, or what health condition would ruin the quality of life for our dogs, before making breeding choices based primarily on health testing, testing that if used incorrectly could eliminate other necessary qualities from the breed’s gene pool. Using testing to learn what, if any, health condition might be passed from one generation to the next is a wonderful tool, but it is not the only tool that a breeder should be using. Utilizing health testing to obtain the appropriate result in breeding requires very judicious application on the part of the breeder, who must also keep in mind the continued genetic diversity of the gene pool, as well as the overall soundness of the breed both physically and mentally.

Why, for example, would one choose to breed an OFA fair bitch to a dog because he had OFA good or excellent hips but also carried an unsound front, instead of breeding her to an OFA fair dog who is sound and beautifully moving both front and rear? In this case the breeder might get one or two additional puppies with better hip ratings (might) but the breeder will also be adding some puppies with those unsound fronts? Did the breeder really improve the breed or the gene pool with that breeding? Or, what about choosing to breed the Rcd4 carrier bitch to the Rcd4 clear dog whose parents both died of cancer at age 7, instead of breeding to the Rcd4 carrier dog whose parents died of old age at 13. We don’t have DNA tests for cancer available for Gordon Setters, but we do know that cancer causes the death of many Gordon Setters before their time, and we know the history of certain cancers can be prevalent in families. By theory, 25% of the puppies in the Rcd4 carrier to carrier litter could be affected, and at age 10 there may be one, perhaps even two of those affected dogs who might (there’s that word might again)  go blind from late onset PRA. Doesn’t the carrier to carrier litter – as a whole – have a better chance of living a healthy, happy life until old age takes them from us? Which choice does a breeder make and how does it affect the diversity of the gene pool? What if the breeder decides not to do either breeding because they don’t like the health choices? Can the diversity and size of the gene pool continue to be maintained if this were to be the constant decision?

So, why all this fuss about the gene pool, and gene pool diversity, and strength and size of the gene pool? A relatively simple example to help us understand is to look at the mixed breed population, and their reputation for being “healthier” than their purebred counterparts. Why is that? Genetic diversity is solidly at play. Odds are there are no common ancestors for generations in the pedigree of any mixed breed dog. A huge and diverse gene pool lies behind the mixed breed.

Before you decide I might be plumb crazy talking here about an issue with the size of gene pool let me ask you if you’ve read and absorbed, yes absorbed to the point where it makes perfect sense to you, the article at the Institute of Canine Biology by Carol Beachat PhD “Is your breed drifting?” (point and click on the bold printed title to link to this article)

As I look at the Gordon Setter in general, comparing them to other purebred dog breeds, I believe that Gordon Setters have relatively few genetic health issues that occur regularly. We are lucky in that respect. However, we cannot hope to improve the health characteristics we’d like to change, if our gene pool continues to shrink to the point where the majority of dogs are related, where there is not sufficient diversity to enact change. We need a diverse and a large population and we need responsible breeders who understand how to accomplish those health driven goals while maintaining the integrity of the breed.

As I look at dog show entries, where the rubber meets the road when it comes to proving the merit of our breeding stock, I find an ever decreasing number of Gordon Setter entries along with a decreasing number of new faces joining the ranks of breeders. Those who are showing today find ourselves scrambling to locate shows where there will be points, majors are difficult if not impossible to find unless sometimes you can bring your own entry – which accomplishes what exactly as far as improving the breed when you’ve finished a dog simply by winning over your own breeding? Specialties are struggling to build 5 point majors and many are no longer able to do so, despite offering two shows in one day. Our National Specialty entries have dropped from all time highs of between 450 to 550 dogs in ’93, ’94, and ’95 to approximately 220 entries for 2015, half the number that were participating 20 years ago.  Fewer entries, fewer breeders, fewer litters equals a smaller gene pool and thus loss of genetic diversity. To me this issue is two-fold; as breeders we need to appropriately and wisely utilize health testing without the elimination of too many dogs from the gene pool, and secondly we need to address the shrinking gene pool by understanding that we need to bring new breeder/exhibitors on to follow in our footsteps, to pick up the reins and drive on.

Many of you have been at this breeding/exhibiting thing for a while now. I’m curious how you feel about these concerns or better yet do you even believe there are such concerns? What would you change if you believe change is needed? How would you drive change? What do you think could be utilized to bring about improvement? Who do you believe is responsible for leading change in the breed? Can or should breeders accept responsibility for driving change?  How can breeders mentor others? So many questions and opinions, let’s start a discussion by sharing them, discussion is the first step. Your thoughts and comments are very welcome here, do remember to be respectful of others please.

For those of you who are Gordon owners but perhaps not involved in breeding and showing, what might entice you to change your focus, what would drive your interest in showing/breeding Gordon Setters? How would you want to learn? Who would you want to learn from? As above, your respectful thoughts and comments are welcome here.

To share your thoughts you may use the reply field at the very bottom of this article or click “Leave a Comment” at the very top of this article.

I’d like us to talk to each other people, as I believe change is needed and that is why I write this blog for you…to bring change through the sharing of information, common goals, and a love for our breed, the Gordon Setter.
