Plenty of stupid opinions when it comes to dogs. The fact that the OP is considering a pair of Dobermans is a bit concerning. Get a family dog from a breeder that focuses on healthy dogs with calm temperament. Think lab, golden or springer. Other breeds may be as good, but none will be better. Even the best breeds can be screwed up by a bad trainer. Plan on obedience classes with the dog AND the daughter. The dog will be around quite a while. Choose wisely and train well.
