Spot on oldnog, working ability first and last. Named lines fine as it gives an indication that the dog has had effort and thought put in to it,s breeding to produce whats required . It,s not a garentee though , as not all dogs will reach standard what evers in them , just how it is.Every thing else is subjective as we all favour different things ie breed , colour , coat ect. You can spend 20 years getting your own line or fork out on a garenteed dog the choice is up to the individual .No rules , so you can take the route that suit,s you depending on your free time , space and cash flow.....En
