The Importance of Breed History
by Anne Allen
It is no secret that I am a Griffon history buff. I believe it’s important to know the history of our breed and breed standard to understand and guide the breeding of Griffons today.
Unfortunately there are not many resources in the English language, and I’ve had to rely on using sources in French, with the help of a few bilingual Griffonniers. From these sources one can learn of the breeding strides and dilemmas that our breed’s founder, Eduard Korthals, faced in his endeavour to create the ideal versatile hunting dog.
It would be very difficult, if not impossible, to recreate Korthals’s breeding program today, given the limitations and restrictions in many areas on the number of dogs one can keep. Korthals produced hundreds of dogs using inbreeding and line breeding, keeping for breeding only the very few that met his stringent expectations in type and performance.
These relatively few dogs that possessed and reproduced the qualities he sought and that consistently reproduced themselves were the foundation of the Wirehaired Pointing Griffon breed.
Within just over a decade or so of establishing his breeding program, in 1887 Korthals wrote the breed standard that was subsequently adopted by 16 Griffon breeders who shared his vision—and is, in effect, our AKC standard today.
So what are we to learn from Korthal’s experience some 125 years later? Today’s breeding dilemma for Griffons enthusiasts is how to manage those dogs that are either carriers of or exhibit tan-point genetics. According to coat-colour geneticist Dr. Shiela Schmutz, of the University of Saskatchewan, tan-point coloration is a breed trait of certain sporting dogs in England, commonly found in English Setters and English Pointers, but not found in purebred Griffons.
While still scientifically inconclusive, the emergence of tan-pointed Griffons suggests a crossbreeding of some sort. When Korthal’s Griffons of the late 1800s showed great field success in various European contests and exhibitions, there were those who believed this success was only possible with an infusion of English blood, namely from the wider-ranging, faster setters and pointers.
To his detractors Korthals responded emphatically, “I declare herewith that my main concern was always to keep the breed pure, and in breeding only griffons I never added any blood of another breed. The improvement of the breed was achieved only and exclusively by selection, training, and methodical breeding.”
In his historical account of the breed, le Griffon d’arret a poil dur Korthals, Jean Castaing says, “Furthermore, as for the fiery tint, in spots or traces, it is also to be forbidden, for it also indicates a misalliance.”
Korthals denied the use of English blood in his breeding program—blood that would have produced tan points and also black, a disqualifying trait in the standard. Korthals would have culled from his breeding programs any dog that either possessed or produced these faulty traits.
We have the only Griffon gene pool left in the world that is not pervasively tainted by the tan-point gene. Tan points are not in the breed standard.
Why breed a dog or bitch that produces a substandard trait of uncertain origin or impact as of yet? Let history be our guide to the future. Korthals wouldn’t have selected for tan points.
We shouldn’t either.—Ann Allen

A word on K-Locus Testing and the KBKB result.
Most breeders in the UK and abroad will test for the K-Locus and will advertise that the sire and dam are "both KBKB". What exactly does this mean? Or more importantly, what exactly does this mean for you, the potential puppy buyer. A KBKB test result indicates one and only one thing: the tan point colouration (as seen in Dobermans, Gordon Setters and Rottweiler’s etc) can not be transmitted by the dog. It does not prove that the dog has not inherited any other genetic problem.
Even a puppy from a KBKB x KBKB mating indicates the parents were free from the colour deviation gene, however, a
"KBKB" dog can still have a KBky father or mother or sibling. So what to do?
LOOK AT THE PEDIGREE. Unless you look at the pedigree and I mean a minimum of 10 generations there is no way to tell if you have just purchased a hybrid or a genuine Korthals Griffon. The contaminated lines are known-look for them. Ask about sibling results of both the sire and dam of the puppy.
Testing- unless the actual test is performed by a vet and submitted by the vet along with the microchip number or tattoo, as with hip and elbow scoring, what guarantee do you have that the test is even on that specific dog? You don't. The tests are ordered on-line and it is the owner who swabs the inside of their dog's mouth and submits the test.
Instead, it is best for you as a potential puppy buyer to obtain the kit and request to swab the dog yourself. If only one of the parents are available to test then require the other dog to have a vet certified test performed. If the breeder refuses you then know you might have a problem.

But again- the test is not even needed if you know how to read a pedigree and know what to look for.
