Fortunately, by the advent of the Twenty-First Century, the controversy surrounding Silver Labs subsided except for a few remaining breeders of "standard" colors. These remaining opponents of Silver Labs are the K-9 version of the "Flat Earth Society". Unfortunately, those holdout breeders who refuse to acknowledge AKC's acceptance of silver labs, continue to confuse the general public by making unfounded accusations about the purity of the Silver Labs breeding. In an attempt to quiet the ranting of the more vocal opponents of Silver Labs, one breeder of silvers offered a $100,000.00 Silver Lab Challenge to any of these "experts" who wished to put their money where their mouth was concerning their accusations surrounding the ancestry of silver labs. And to the man, not one of those "experts" you see on the internet was willing to stand behind their Flat Earth accusations regarding Silver Labs.
Are Silver Labs Pure bred Labrador Retriever?
DNA testing and mapping of silver labs was done during the close of the Twentieth Century and meticulous investigation of each silver labs ancestry was conducted by investigators from AKC. All conclusions were the same, i.e., "there was no reason to doubt that the dogs were purebred Labrador Retrievers," (see conclusion issued by AKC). Amazingly, the Flat Earth Opponents of Silver Labs counter these scientific conclusions with the incredibly insane accusation that the "cross-breeding" which allegedly produced the Silver Labs was either covered up by line breeding or happened to long ago to be detected by DNA testing. If anyone ever needed an indication of just how ignorant opponents of Silver Labs are, this statement should be the key. Every K-9 carries in its genes a complete history of its ancestors going all the way back to wolves.
Everything written about the Silver Labs is based upon speculation. One statement that is commonly made is that there had to have been a Weimeraner introduced into the bloodlines to produce the silver color. This statement has been proven false. UC Berkley studied the genetic makeup of the Silver Lab against that of the Weimeraner. Researchers concluded that it was not the same.
