Another question you might consider.....is the price tag on the pup gonna be reasonable to your budget. Would recommend to ask more specific questions on the sire and dam and who has (Actually Witnessed) their performance not just the name on the registry and the calculated % of a dog that is generations back.
Might hold some hum dingers back a ways...but if everything else in between is poop.......ya gonna get a taste.
Justa lil devil advocacy.

Hope ya get a goodun regardless bud.
