Both the Doberman and the Rottweiler are German working breeds bred for a variety of tasks; use as guard dogs being the most common.
The most common color of both breeds is a predominantly black coat with tan points. The Rotterman usually displays this coloring as well. Dobermans occasionally have fawn, red or blue coats that may be passed down to the Rotterman puppy if the parent is that color or has the color dilution gene.
Both dogs have short coats and shed often. Despite shedding, they do not require a lot of maintenance.
The Rotterman has a personality similar to both breeds and is very intelligent. Any aggression is almost always aimed at strangers, not owners. Rotterman breeders focus on breeding a family-friendly, obedient dog.
Rottweilers and Dobermans are roughly the same size; however, Rottweilers are built stocky, compared to the Doberman's slim appearance. Rottermans are somewhere in the middle, often appearing to stand on their toes like Dobermans, but having the thicker neck and stronger chest of a Rottweiler.
