A quote from the website where you (CagneyDog) got the picture of mom and pups:

They started breeding labs after Marcie rescued their now stud dog Buddy from someone that had neglected him and tied him up on a short rope in a cement stall in a cow barn. He was 2 years old, untrained, not housebroke and on his way to the animal shelter when Marcie found him on this farm. To make a long story short, Buddy has come a long way and he and Marcie are practically inseparable.
They do not know this dog's lineage. He should have never be bred. So you can rule this breeder out as responsible.
