    Basically, people buy certain breeds expecting a certain behavior and then train these breeds to express said behavior, which makes it difficult to examine whether said behavior is due to the nature or nurtured or how big a role either plays.

    All the authors need to do is go to a handful of working dog breeders and watch the puppies. They will see quite clearly that breeding dogs for traits works.
