I got my dog Damien back in November 2012 when he was 71/2 months old. He is now 2 yrs. People would ask what kind of dog he is and I would just say shepherd mix. His height: 21-22 in and weight: 50lbs. He is all black with a white blaze on chest and white tip on the tail. His ears are erect but one is floppy. What is your guess on the type of breed?
