I hope he meant that the suspected parents were dna'd to prove the pups were out of the two parker dogs
He sent DNA off the puppies and the two parents and it came back positive that those pups were in fact from those two dogs. So since those two dogs were full Parkers, the puppies were to is all he was meaning.
I had the same thing outta the same line except three pups came out black and tan. Larrys Blackie dog had a littermate sister that was black and tan. It's a long ways back in the ped but it sure popped up big time in my litter.
