Imagine this situation: There's a litter of cute pups, that seem to fit your requirements in terms of looks/exercise they'll need/size/etc. They have been raised well, by the look of it, and seem healthy and well socialised. The parents have had all necessary health tests. The breeder is happy to answer all your questions, and tells you that a top behaviourist has assessed the mother's temperament and recommended breeding her. But when you arrive, the pups' mother (behind a babygate) barks at you a lot, though she stops when the breeder distracts her with some treats, and when you meet her properly later she barks at you again as you offer fuss and dances away from your hand. Eventually she warms up to you and by the end of the visit is trying to sit on your lap. Would you buy one of the pups or not?
