At the risk of being seen as difficult, let me point out that the commonly repeated lines, framed above, are mostly bunk.
A pedigree is simply a piece of paper. By itself, it tells you nothing, and may not even tell you what breed the dog is.
Conformation. What does that word even mean? Conformed to what? Conformed to a "standard" that has been changed several times and remains so vague it can be nearly impossible, absent a caption line, to know what breed of dog is allegedly being described?
Performance is right -- but only for a performance breed. There is no job that a Maltese or an English Bulldog does that a Papillon or a Beagle cannot do better.
The poetry and repeated rhetoric that underpins the world of dogs tends to fall apart quickly if it is examined very hard. Look at the phrase "form follows function". Nope. That's not even true in that sentence, much less in the world of herding dogs, guard dog, or dirt dogs!
