Rottweilers are predisposed to hip and elbow dysplasia, subaortic stenosis (a narrowing of the heart's aortic valve that can cause fainting or exercise intolerance and is often first detected as a heart murmur before age one), and osteosarcoma (bone cancer), which occurs at notably elevated rates in the breed. Ask breeders for OFA hip, elbow, and cardiac clearances.
Large-breed puppy formula through the growth period helps control growth rate and protect developing joints. Rottweilers are prone to obesity as adults, which compounds joint problems — portion control matters throughout their life, not just as puppies.
The short double coat sheds heavily twice a year (spring and fall) with lighter shedding the rest of the year; weekly brushing keeps it manageable. Otherwise low-maintenance.
Early socialization and obedience training are essential, not optional, given the breed's size and protective instincts — a well-socialized Rottweiler is famously good-natured, but the training needs to happen deliberately. They need at least an hour of exercise daily; without it, boredom shows up as destructive chewing.
The Rottweiler traces back to drover dogs that accompanied Roman legions across the Alps, herding and guarding cattle for the army; when the Romans settled in a German town later named Rottweil, the local dogs became known as Rottweilers and continued driving cattle to market for centuries. The breed nearly disappeared by the late 1800s once railroads replaced cattle droving and local law banned using dogs to pull carts, but German fanciers revived it for police and military work in the early 20th century. The AKC recognized the breed in 1931.
The breed standard describes a calm, confident, and courageous temperament with a self-assured aloofness that "does not lend itself to immediate and indiscriminate friendships" — Rottweilers are bred to assess situations rather than react instantly, which combined with a strong protective instinct is why the standard also explicitly penalizes shyness or unprovoked aggression as faults, not correct type.
