Origin of the Rottweiler

The Rottweiler originated from the Molossus, a now extinct breed of dogs from Europe. The Molossus was a Mastiff type dog of extreme power and large size. The Romans used Rottweilers as war dogs. The Rottweilers closest relatives are the Greater Swiss Mountain Dog; and the Bernese Mountain Dog.

"Rotties" were first used as cattle dogs, cart pullers, and to protect merchants money as it was tied around the dogs neck.
