A good breeder understands how to manipulate genes within their breeding stock in order to produce the kind or type of dogs we want. A good breeder is not one who breeds less dogs - it is someone who breeds dogs well. A good breeder will breed only for the improvement in type and structure. A good breeder will screen his dogs for health problems, and makes intelligent and informed choices based on the results of those tests to minimize the risk of producing unhealthy animals. A good breeder takes the time to learn the basics of genetics, anatomy, and canine behavior before he starts a breeding program, and then continues to study throughout his years as a breeder. He stands behind his dogs, and shows his dogs in competitions - because he understands that the purpose of competition is to evaluate the breeding stock.
