What's the difference between a rottweiler and a doberman pinscher? Dog Breed Discussions
They are two completely different breeds that other than the black and tan coat pattern look nothing alike. The are also quite different temperament wise. If you can't even tell the breeds apart physically,and aren't willing to do the research to learn about the breeds (asking questions on YA does not count as research) I would suggest that you get neither breed. Neither is a breed that is appropriate for inexperience owners or those unwilling to that the time to learn to deal with the breed properly
