I have no problem with carriers, I to sometimes suspect they can be the better dog but have no proof of that. It's not just marking but the overall disposition and attitude of the dog. If I were breeding I would not want that to be a factor just because of how people feel about it. So it is not the fact that some pups are carriers but the fact that people have a problem with it. I would take a carrier from a breeding I like in a heart beat. Two out of 3 of my dogs are carriers and I would not change that even if I could
