Let her have her first heat then breed her on her second one, that is what i did to lindsay and she has had two very good litters, I mean you saw all the pups, but yeah just make sure you give her a lot of attention, if you do that she will be just like Lindsay. Also make sure you make her listen to you at all times so that she is obedient. That way if she does something bad and you yell at her she will know she did something wrong
