hands down i would go with von Moeller Hof dobermans here in charlotte, nc. they have a winter 2013 litter and these pups will be very high drive dogs with solid temperaments and will make excellent working prospects for schutzhund, obedience, agility, tracking, SAR, etc.
not sure what experience you have with working sports, but this is your best bet for a schutzhund prospect in the area. chris is active with the UDC and Working Dobermans of the Carolinas. she also does extensive health testing. von Moeller Hof Dobermans
also, if you plan on exercising your pup by jogging/running, you will need to wait until he or she is about 2 years old. a pup's body and bones cannot handle forced exercise like running and can be detrimental to his or her structural development.
furthermore, you said you and your family. when communicating with breeders, be sure to inform them of any children in the household. some breeders have certain rules about placing pups in homes with children, especially with larger breeds. a rambunctious puppy and a wild-child toddler at home can be extremely difficult to manage and you may be looking at younger children getting knocked around by the pup and possible injuries.
good luck in your search.
