I Googled it here and here is what I found it was a breeders website CCK's original line of Silver Labs evolved as the product of recessive gene combination from chocolate Labs. Subsequent breedings have proven the Silver color to be a replicable genetic trait with Silver/Silver breedings producing litters of all Silver pups. . What is the controversy over Silver Labs? A. At the end of the Twentieth Century, the frequency of Silver (gray) Labs began to increase in North America due to an increase in the number of chocolate Labs in the gene pool of Labrador Retrievers, and these Silver Labs in turn fueled an enormous controversy within the Labrador community. Fortunately, by the advent of the Twenty First Century, the controversy surrounding Silver Labs subsided except for a few remaining ignorant breeders of "old standard" colors. These remaining opponents of Silver Labs are the K-9 equivalent to the "Flat Earth Society". Unfortunately, those ignorant holdout breeders (who refuse to acknowledge AKC's acceptance of Silver Labs as pure bred Labrador Retrievers) continue to confuse the public by making unfounded accusations regarding the genetic purity of CCK's Silver Labs. In an attempt to quiet the ignorant ranting of the more vocal opponents of CCK's Silver Labs, we offered a $100,000.00 Silver Lab Challenge to any "expert" who wished to put their money where their mouth was concerning their accusations surrounding the ancestry of Silver Labs. As a surprise to no one, not one "expert" you see on the internet was willing to stand behind their "Flat Earth" accusations regarding CCK's Silver Labs. The reticence of those "experts" speaks volumes as to who is telling the truth in the Great Silver Lab Debate. Q. Are Silver Labs pure bred Labrador Retrievers? A. DNA testing and mapping of CCK's Silver Labs was done during the close of the Twentieth Century, and meticulous on site investigations of each CCK Silver Lab's ancestry was conducted by investigators from AKC. All conclusions were the same, i.e., "there was no reason to doubt that the dogs were pure bred Labrador Retrievers" (see conclusion issued by AKC). Amazingly, the Flat Earth Opponents of Silver Labs counter these scientific conclusions with the incredibly inane accusation that the "cross-breeding" which CCK allegedly used to produce Silver Labs was either covered up by line breeding (a virtual impossibility with modern DNA tests); or happened too long ago to be detected by DNA testing (which apparently implies CCK performed this feat of magic about 500 years ago). If anyone ever needed an indication of just how ignorant opponents of Silver Labs are, their statements against verification through gene mapping should speak volumes. Every K-9 carries in its genes a complete genetic history of its ancestors going all the way back to wolves. Opponents of Silver Labs who argue they are unable to prove their ridiculous accusations through genetic research show the depth of their ignorance-and the shallowness of their credibility.
Some will be 'genuine' lab dilutes, after all, weims got their colour from dilute of their ancestors in the same way, but I know for a fact that some of these 'so called' silver labs do have actual weim blood in there. Much quicker to add a weim than mess about for dilutes. Quick/readyness of said pup = more/faster money coming in. From the few adults I have met first hand, i've never seen ears quite like that on a purebred lab before. And they had papers.
Merle Poodles originally had AKC papers until people complained that they were crosses and they pulled them all! Becky
But what sort of papers, if KC it will say colour unrecognised. There are, of course, commercial concerns that will register anything you just pay your money and they will write whatever you tell them too.
