The breeder would be the best one to ask about that. They spend all their time with those puppies as they grow up, so they should have a pretty good idea about their personalities. Like, when we bought our golden retriever, the breeder met with us at least 3 times as the pups grew up to talk to us, find out what we are wanting in a dog, find out our lifestyle, watch us interact with the dogs, etc. and she directed us to the puppies that would be best suited for us. There were 9 (or 7
) in the litter, so of course, there was an arrangement of personalities.
