Yes, I agree, I think it depends on the family, if a breeder can meet all family members and watch how the children interact with dogs I suppose that helps.
Sam, I wonder if Charlie did come from a novice breeder who only bred one litter and didn't want to dock them? Not that it matters now, he's lovely. Beano has a lot of coat doesn't he? I couldn't believe how long his coat was on the pictures you posted of your walk.
