'Rottweiler' originates from German, specifically the name of the town 'Rottweil', where the breed was developed.

'Rottweiler' changed from the German word 'Rottweiler Metzgerhund' (Rottweil butcher's dog) and eventually became the modern English word 'Rottweiler'.

Initially, it referred to a dog used for herding and guarding livestock, but over time it evolved into its current meaning of a specific dog breed known for protection.
