An image of an angry Doberman
An angry Doberman in a parked car
The Doberman, or Doberman Pinscher, was a breed of domesticated dog, originating from Germany, on Earth.
While searching for a vacant automobile to "borrow", during a time travel visit to Earth in 2004, Jonathan Archer had a startling encounter with a barking Doberman that was locked in one of the cars he attempted to access. (ENT: "Carpenter Street")
This dog's breed wasn't scripted; in the final draft script of "Carpenter Street", it was referred to simply as "a vicious-looking dog" which barked "loudly".
The image of an angry and barking Doberman was among multiple disturbing thoughts that Tuvok imposed upon the Mari Guill during a mind meld in 2374. (VOY: "Random Thoughts")
