Rottweilers were originally bred in Rottweil, Germany to be used for herding, guarding livestock, and for protection. They were known as Rottweiler Metzgerhund, meaning Rottweil butchers dogs, because their main use was to herd livestock and pull carts laden with meat to market. They were also used to guard money and as police dogs. Rottweilers are a breed of working dogs, which means they are intelligent, easy to train, and very headstrong. They are known for their confidence and intelligence, but they require a steady training regimen to learn social skills. Rottweilers are rather large, playful, and excitable dogs that are not recommended for first-time owners.
