Well I would recommend my breeder for a good 'pet dog'. She also has trained adult dogs from time to time, usually retired breeding females or young females or males that ended up not going into her breeding program. I'm not a mother nor do I know your experience with dogs but I'd be nervous with a puppy and two year old but that's just me! My puppy has been very good and gentle with children though... He's very confident, he's never spooked and he's extremely laid back.
Jackie(the breeder) also stands behind her dogs for life, I've emailed her a few times since I've had my pup and she answered my questions no issues! She's breeding more for healthy well tempered dogs then for show or sport specifically now that's she older and can no longer compete herself in sports.
