This is an excellent point. Unfortunately as breeders, we are still limited by the knowledge available regarding the background of each line. It sounds simple to say that you just don't breed a dog with a poor bite to one that may carry a recessive DNA trait for this same fault. DNA research has not reached a point in regard to dog breeding that allows us to look at the DNA strands and say "OH, there is the gene for an underbite" . We must rely on getting very familiar with the traits shown and produced by each dog in previous generations of a prospective breeding dog's pedigree as far back in the line as possible. This is the only way to proceed with any confidence that you will not have a nasty surprise in a litter you produce. Even with this extraordinary amount of painstaking research. Mother Nature can still toss a curve ball in your direction, but as Kathy said, it's easier to sleep at night if you know you did your utmost to produce a healthy, quality pup.
