According to the FCI Standard, the Rottweiler is considered to be one of the oldest dog breeds. Its origin goes back to Roman times. These dogs were kept as herder or driving dogs. They marched over the Alps with the Roman legions, protecting the humans and driving their cattle. In the region of Rottweil, these dogs met and mixed with the native dogs in a natural crossing. The main task of the Rottweiler now became the driving and guarding of the herds of cattle and the defence of their masters and their property. This breed acquired its name from the old free city of Rottweil and was known as the "Rottweil butcher’s dog". The butchers bred this type of dog purely for performance and usefulness. In due course, a first rate watch and driving dog evolved which could also be used as a draught dog.[3][10]
The buildup to World War I saw a great demand for police dogs, which led to a revival of interest in the Rottweiler. During the First and Second World Wars, Rottweilers saw service in various roles, including as messenger, ambulance, draught, and guard dogs.
The Deutscher Rottweiler-Klub (DRK, German Rottweiler Club), the first Rottweiler club in Germany, was founded on 13 January 1914, and followed by the creation of the Süddeutscher Rottweiler-Klub (SDRK, South German Rottweiler Club) on 27 April 1915 and eventually became the IRK (International Rottweiler Club). The DRK counted around 500 Rottweilers, and the SDRK 3,000 Rottweilers. The goals of the two clubs were different. The DRK aimed to produce working dogs and did not emphasise the morphology of the Rottweiler.
The various German Rottweiler Clubs amalgamated to form the Allgemeiner Deutscher Rottweiler Klub (ADRK, General German Rottweiler Club) in 1921. This was officially recorded in the register of clubs and associations at the district court of Stuttgart on 27 January 1924.[11] The ADRK is recognised worldwide as the home club of the Rottweiler.
In 1931, the Rottweiler was officially recognised by the American Kennel Club.[12] In 1936, Rottweilers were exhibited in Britain at Crufts. In 1966, a separate register was opened for the breed. In fact, in the mid-1990s, the popularity of the Rottweiler reached an all-time high, with it being the most registered dog by the American Kennel Club.[13] In 2017, the American Kennel Club ranked the Rottweiler as the eighth-most popular purebred dog in the United States.
The Rottweiler (/ˈrɒtwaɪlər/, UK also /-vaɪlər/)[1][2] is a breed of domestic dog, regarded as medium-to-large[3][4] or large.[5][6] The dogs were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers' dogs,[7][8] because their main use was to herd livestock[3] and pull carts laden with butchered meat to market.[7] This continued until the mid-19th century when railways replaced droving. Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, guard dogs, and police dogs
