Dobermann or Doberman Pinscher is a dog breed that was started in the 19th century. It is named after Friedrich Louis Dobermann (1834-1894), one of the first people to breed these dogs. When he started the breeding process, he took dogs that showed little fear, and that were valorous (or brave). The result is a working dog breed. Even shortly after the start, such dogs were used by police forces or as guard dogs. Today, they are also used as search and rescue dogs or as guide dogs for blind people.
The dogs are between 63 centimetres (25 in) and 72 centimetres (28 in) tall, and up to 45 kilograms (7.1 st) in weight. Dobermann dogs can be aggressive, and in certain countries or territories a permit is needed to own or breed them.
