I plan on moving into my first house this year and I plan to buy a couple dogs. It might not be for a little while after that (might be longer) until I'm settled cause it isn't fair to the dogs. But a lingering question on my mind is which breed would you suggest between Doberman (5th smartest breed) and Rottweiler (9th smartest breed)? Rottweiler read like they pack more muscle and have more weight to them. That true? Would a Rottweiler be a better guard than Doberman? Its a few factors (friendliness, intelligence and strength) that I'm weighing. I've had retrievers all my life but they couldn't do squat but bark if someone ever broke in.
