There is a lot of controversy surrounding the DNA testing of dogs, specifically breeders versus buyer’s mentality, but there is no way to deny that DNA testing can significantly help any dog breed. The problem with breeding is that is has been going on for so long and certain breeds are genetically predisposed to certain problems, some of which can be quite serious. Reputable, responsible dog breeders have always made a point of not breeding dogs which display any of these problems, but this is no longer enough. The problem with this technique, as breeders have been noticing for quite a while now, is that you can still end up breeding a carrier of a breed specific health or behavioral problem without even knowing it – the carriers never necessarily exhibit the symptoms of the problem itself, but they pass it on to their puppies, and then breeders are left with a litter of whelps which are either carriers themselves or ultimately develop the problem.

With DNA testing, it is now possible to test for certain genetic defects and problems. That way, breeders can end the cycle and they will no longer have to take chances which inevitably result in breeding a carrier and making his or her progeny suffer for it. Given that the ultimate goal of the good, responsible dog breeder is to make every litter of puppies better than his or her parents, these DNA techniques give them a much better chance to do this. They will be able to get closer and closer to achieving the Breed Standard, something that it has long been understood could not ever really be reached. Now, it is potentially possible – or at least more possible than it has ever been before.
