I agree that white boxers should not be purposefully bred to some extent like some of you said, but what if in the litter there is a white boxer who is perfectly healthy?

This is the
correspondence between a breeder and Dr George M. Strain.
Dr Strain is one of *the* foremost experts in canine deafness in the world.
For those who can't be bothered to read the whole thing here is a small portion of it.
Question submitted by breeder:
Quote:
I am interested in knowing if introducing white boxers into the gene pool as breeding specimens can in turn lead to this deafness increasing in coloured boxers, possibly due to the whites passing on a lot of minus modifiers?
One aspect of the "proposal" that I am unclear on is the deafness issue. Is the congenital deafness in boxers limited to whites? If not, could the introduction of whites into the gene pool also introduce the pigment problem in the inner ear to our coloured boxers as well?

It is my opinion that white boxers carry a version of the regulatory gene that causes over- expression of the piebald gene, producing heavy white color, blue eyes, and deafness. Breeding these dogs back into the boxer gene pool will very likely increase the overall incidence of deafness in ALL boxers (white or otherwise).
If asked, I would be opposed to breeding white boxers -- to either whites or colors. If this practice is continued the prevalence of deafness in all boxers will increase as has happened with other breeds. I know that there is a strong group of advocates for white boxers, mostly because there is always attraction to something novel. To me it seems totally without logic to continue a breeding practice which, based on all available knowledge, will increase the prevalence of hereditary disease in a dog breed.

Breeders are already trying to rid the breed of Cardiomyopathy, Aortic Stenosis and other genetic problems so why on earth would they want to introduce another problem to the breed?

Why someone should not be able to show him? Just because he is white? I also know your response, letting white boxers compete will encourage breeders breeding more white boxers but even this can be controlled by registries like CKC and AKC. CKC and AKC could at least make a separate category for white boxer showing.

Conformation is done to
assess breeding stock. It is not to pick the cutest, sweetest, smartest dogs. So there is no reason for white boxers in the conformation ring -
they are not breeding stock. I don't mean this to sound rude or offend you but what would it achieve, what is the point? We do things for a reason right? People show their dogs in the conformation ring to see if they are good examples of the breed to use as breeding stock (the reason for conformation ring), whites should not be bred with so what would the reason for showing them in the conformation ring be? I will assume that you will say something like: "to prove they are just as good as any other boxer", I agree they are, but again this should not be done in the conformation ring - they are not breeding stock. Prove that point in obedience or agility, where the main aim isn't assessing suitability as breeding stock. My girl is brindle but even she has no place in the conformation ring

and many other coloured boxers who don't meet the breed standard don't either. Whites are able to participate in the obedience ring, and in agility, which would be a great way IMO to show people that they are "all Boxer", intelligent, easy to train, have a great temperament and generally great dogs.

Only about 17% of whities are born deaf.

That really depends on where you are getting the info from and if they used BAER testing.
I have found one that showed 20.67% of white boxers were deaf - without BAER testing. Had BAER testing been done it was estimated (based on research and results from other breeds with the same issue) that the 20.67% figure would doublet o just over 40%

The cause of the deafness associated with the white colour is the absence of pigment cells in the inner ear resulting in a loss of sensory hair cells at about 6 - 8 weeks of age.
