Yeah, German Shepherds are great dogs and deserve to be on the list.
But Rottweilers are fiercely loyal and protective of their family, and actually more intimidating than a Doberman. The one we had, his previous owner said people would ask if he was a Doberman on steroids. :D
When we first got Sheldon the Rottweiler,a friend of ours came our house and his first comment was”Your dog’s way too fat!”Then he started to pet Sheldon and realized it wasn’t fat,it was all muscle.He’s 135 lbs of muscle and attitude.
