I googled silver labs and they claim it is a color phase like chocolates or black. they are accepted by the AKC according to silver star kennels website.
I thought they just crossed a weimereiner to lab
interesting
korey Sorry to be contrary but.....Not acceptable.
http://www.akc.org/breeds/labrador_retriever/index.cfm Color
The Labrador Retriever coat colors are black, yellow and chocolate. Any other color or a combination of colors is a disqualification. A small white spot on the chest is permissible, but not desirable. White hairs from aging or scarring are not to be misinterpreted as brindling.
Black--Blacks are all black. A black with brindle markings or a black with tan markings is a disqualification.
Yellow--Yellows may range in color from fox-red to light cream, with variations in shading on the ears, back, and underparts of the dog.
Chocolate--Chocolates can vary in shade from light to dark chocolate. Chocolate with brindle or tan markings is a disqualification.
Silver, Gray, White are all colors that are not acceptable "for registration purposes". However color means virtually nothing when it comes to the ability of the dog as a waterfowl dog. I know some people just want to be different. You could spend a good deal less money and get a really nice registered lab from a field pedigree. As far as the claim that they "are" acceptable......if you call it chocolate on the paperwork.... AKC ain't gonna come check it.
