Rottweilers descend from Roman-era drover dogs and take their name from Rottweil, Germany, where they drove cattle to market and pulled butchers' carts. When railways ended that work, the breed moved into police, search and guard roles. A Rottweiler is powerful and compact, with a short black coat and rust markings, and adults commonly weigh 75 to 135 pounds.
Within the family many Rottweilers are affectionate and playful, leaning against their people while staying reserved with strangers. In Tyler, that means a dog that watches the door, needs good leash manners around neighbors and other trail users, and does best with steady training and clear routines. Dogs vary, and an adult dog's temperament is often easier to read than a puppy's.
