Rottweilers descend from Roman-era drover dogs that moved cattle to market in the German town of Rottweil, and later worked as police, search and guard dogs. The result is a powerful, compact black dog with rust markings, a broad head and a calm, watchful manner.
At home, many are affectionate, playful and happy to lean on their people, while staying reserved with strangers. In Reno, that watchfulness shows up on busy trails and at dog park gates, so early socialization and steady, reward-based training matter. Adult dogs in rescue often have a known temperament, which makes matching easier, though every Rottweiler is different. Expect moderate shedding, a short coat that needs little beyond brushing, and a lot of strength on the end of the leash.
