It's more to do with the fact that white boxers carry the deafness gene and by breeding white boxer you are potentially adding to the already growing number of deaf puppies, harvey was from a red x brindle breeding but he and 2 others came out white, luckily harvey can hear but the others were deaf. The 2 deaf puppies are now in white boxer rescue where any potential owners are taught hand signals etc and have constant help with raising a deaf boxer.
