I have had Dobermans for over 40 years and have 2 now (see profile). Some people are concerned when we walk Bella and Rex in the campgrounds even though they are very friendly we respect their space and walk around or adjust our walk. We have had more problems with the OWNERS of little dogs who think its cute when thier little dogs bark at big dogs. As a firefighter I am gone for 48 hours or longer at a time, it is comforting to now my wife and property are safe when I am not there. I wouldn't have any other breed myself.
