Rottweiler vs Doberman

The Rottweiler (/ˈrɒtwaɪlər/, UK also /-vaɪlər/) is a breed of domestic dog, regarded as medium-to-large or large. The dogs were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers' dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market. 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, as guard dogs and police dogs.
The Dobermann (/ˈdoʊbərmən/; German pronunciation: [ˈdoːbɐman]), or Doberman Pinscher in the United States and Canada, is a medium-large breed of domestic dog that was originally developed around 1890 by Karl Friedrich Louis Dobermann, a tax collector from Germany. The Dobermann has a long muzzle. It stands on its pads and is not usually heavy-footed. Ideally, they have an even and graceful gait. Traditionally, the ears are cropped and posted and the tail is docked. However, in some countries, it is illegal to do so. Dobermanns have markings on the chest, paws/legs, muzzle, above the eyes, and underneath the tail.
