AKC Stance on Silver Labs
Why The AKC Registers Silver Labradors As Chocolate
"In 1987 we conducted an inquiry into the breeding of the litters that contained the dogs that were registered as silver and one of our representatives was sent to observe several of the dogs that had been registered as silver. Color photographs of these dogs were forwarded to the office of the American Kennel Club where the staff of the AKC and the representative of the Labrador Retriever Club of America examined them. Both parties were satisfied that there was no reason to doubt that the dogs were purebred Labrador Retrievers, however both parties felt that the dogs were incorrectly registered as silver. Since the breed standard describes chocolate as ranging in shade from Sedge to Chocolate, it was felt that the dogs could more accurately be described as chocolate than as silver."

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 above 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.
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.
Some K-9 geneticists speculate the gray chromosome is in all K-9 species descendant from wolves. Labs were originally the product of several breeds of hunting dogs, contain a large percentage of Newfoundland breeding in their genetic background, and the production of gray Newfoundland pups is not uncommon in the Newfoundland breed.
