As wewe already know, labs do not come in gray, but some poeple are scammed off into thinking they do, and that they have a rare color in special breeding. Wrong! What people make off as a blue lab is really just a regular ole lab mixed with a Weimeraner, giving the dog the look of a lab with the blue-gray color of the other breed. I saw someone who was marhcing around like they owned the place with the "blue lab." It was hilarious because they didn't know they had a mixed breed they paid 400 dollars for!
These are not labs. If you've heard of these au haven't, now wewe know.
