Rottweiler

The Rottweiler is a robust domestic working breed developed in the German town of Rottweil during the Roman era. Descended from Roman cattle-drover dogs, the breed accompanied Roman legions traversing the Alps to protect soldiers and herd livestock.

The Fédération Cynologique Internationale assigns the Rottweiler to Group 2, Section 2.1, designating Molossian type working dogs. During the Middle Ages, butchers in Rottweil bred these canines to herd cattle to market and pull heavy meat carts, earning them the name Rottweiler Metzgerhund, or butchers' dog. The advent of railways in the mid-nineteenth century curtailed cattle driving, leading to an initial population decline until police departments and armed forces identified their utility in security work. The Allgemeiner Deutscher Rottweiler-Klub formed in 1921, consolidating breeding rules and international working trials.

Male Rottweilers reach a shoulder height of 61-68 cm (24-27 in) with an average weight of 50 kg (110 lb), while females stand 56-63 cm (22-25 in) and weigh approximately 42 kg (93 lb). The coat consists of a medium-length, coarse, flat topcoat with a dense undercoat on the neck and thighs. The coloration is invariably black with clearly demarcated rust-colored markings over the eyes, muzzle, throat, chest, legs, and under the tail base. Breed standards define the temperament as good-natured, placid, devoted, obedient, eager to work, and self-assured under physical pressure.

Weekly brushing with a rubber curry comb removes dead hairs, while twice-yearly seasonal shedding cycles require daily grooming sessions. Working lines require substantial daily physical exertion and mental conditioning through tracking or obedience drills to prevent behavioral deterioration. Common medical vulnerabilities include hip dysplasia, elbow dysplasia, osteochondritis dissecans, and cruciate ligament ruptures. Cardiovascular conditions such as subaortic stenosis affect the breed, alongside elevated risks of osteosarcoma and lymphoma. Due to deep chest anatomy, the breed faces elevated rates of gastric dilatation-volvulus, which veterinarians often counter through prophylactic gastropexy surgery during neutering.
