Temperament is different in each puppy. Ask the breeder...which one is the alpha, who is in the middle, and who is the most timid. Best to pick the Middle one. i had a breeder say let me pick your puppy after she found out our daughter was bit bad by one of our dogs. She picked the perfect puppy for us. Breeder should know temperaments of each one. or at least have a good idea. We like females, other people prefer males. It is up to you on sex. But if you are open then temperament is the most important.
