I agree with u on that Mr.Parker. I bred some of the purest Gr Ch Nigerino dogs in the world not country but world. Red dogs with black mask. We had six liters on the ground at one time and had to keep each liter in separate quaters. The reason being if a liter ever got out and got with another liter there was no way to be able to tell them apart. They where that close. Bred in all different ways threw Nigerino and they where all clones . Yes sir that's when you know you got things right that and their performace matches their pedigree and does what their pedigree says they should do not the other way around because a great beautful pedigree is pure a$$ wipe trash if the dog cannot perform to the level in which he is bred.
Good points Jimmy. I agree with the ped means nothing if the dogs can't perform. With performance animals I was always told don't forget that form follows function. It's great to have uniform looks, but it is even better if they have uniform traits and or characteristics. JMO I guess when you have both generation after generation that would be the proof you do have a line or family at that point.
