I have a female GSD/Bloodhound mix that is 7 months old. She can indeed bark, when her brother and her are together they bark at each other when playing. Ive noticed that she doesnt bark at animals or people when they are near or on the property. All our other dogs will bark if they notice someone driving up the driveway or walking down our street (we live in a rural area so its rare for someone to do so). I would like to encourage her to speak when a vehicle is in the drive.
