Most of what you are asking depends on the individual situation; are they both healthy, same age, same condition, etc etc
However, I seriously doubt that a German shepherd could beat a doberman of any gender. They outrank the GSD as far as guard dog capabilities (#2 on list), not to mention they are stronger and faster - taking a high ranking on both accounts. As far as smarts, Dobermans make the list at #5 and GSD's take the list at #3.
All this taken into account, I believe it's most likely the Doberman will win.
It would, of course, depend on the size and personality of each dog.
the doberman is 3-5 inches taller
absolutely
Not really but the force from a German Shepard and how its trained can overpower or even put the big monster down!
no becaue German shepherds are way stronger
german sheperd
Yes, the German Sheperd is from German, it's German name is Deutscher Schäferhund
i don't think so, German shepherd is a breed that makes the 2 best guard dog, so i recommended you if you buy a bulldog or a German sheperd, NEVER buy a German sheperd with a bulldog, they might tear each other into pieces. But it is up to you, that was just my warning, the choice is yours.
A German Sheperd can run 30 miles per hour.
Yes, if you are responsible you can have a German Shepard, boxer, and a doberman.
no
Another Doberman or a German Shepherd.
No you just have to play it for a couple of weeks then it will tell you have the German Sheperd unless you have the breed at the start.
