Yep.
For years (decades, now) I've heard nay-sayers say that because "I" don't match dogs that my dogs "can't be" fast lane ... and for every single one of those years, bar none, I have bred better dogs and produced dogs that BEAT "dog fighters' dogs" time and again, almost 9-1.
I simply know what winning traits are, how to maintain them in a family of dogs, and can see if they're there or not in practice with each individual in each successive generation.
By contrast, most people never stick with anything long enough to get to know it, master it, and so are forever playing "guessing games" with their random and pointless breeding decisions.
This is absolutely the truth.
And it is especially the truth if you stick with the same family (or winning combo), and select from individuals know to have (and produce) those traits.
Breeding to "a dog" with some traits you like (with a spotty background for them) is a rougher deal ... but breeding to yet another individual with these traits, full of similar dogs in his litter, and in his background, makes getting "the kind of dogs you want" a cinch.
I used to say, "I could produce better dogs from an accidental kennel breeding in my sleep than what MOST people produce traveling, paying stud fees, and mixing bloodlines," ... and, yeah, it was kinda funny to say ... but I wasn't joking.
