"There is most definitely Deer Run in her pedigree. Her sire is the one who has it. I believe Carl stated that it was impossible for only one dog to produce the pied. So he theorized that since she is doubled up on a "clean" line (Damaria) that is where it came from.
If a St. Bernard bred to a Mastiff can produce pieds then that would mean it only takes one.
Yes there where pieds hundreds of years ago, but they should be bred out by now. And if they are not; how do any of you intend to breed HD or anything else out of your lines?
When you have a pied Mastiff that looks like a modern day St. Bernard it does not come from breedings done a hundred years ago. "
Mike, it is correct that there is Deer Run in Dior's line but what I don't understand is why this line, that is bred over here for twenty years didn't produce any pied before. It's easy to point Deer Run as the responsable breeder for pieds. They never did hide they used St.Bernard. What about the others that did. For your information I did have pied in some of my litters in the beginning of my breeding, more then twenty years ago, but they died at birth. We didn't have Deer Run then over here. I don't believe in mutation. There is only one recessive gene responsible for producing the pied couloring. BTW why should the St.Bernard be responsible. Have you never seen a pied Bulldog? Or Pyrenean Mountain Dog, even a Bullmastiff can be a carrier. What about the pied in Newfoundland?
Dior is out of a mother/son combination and it is not so strange that the specific gene doubled up. I find this quit normal. Not accepting the fact that this could come from a clean line is head-in-the-sand politics. Refusing to believe that this could come from a clean line is harming the clean line more then other way round. It makes your cause implausible.
