The Rottweiler is one of the most capable and impressive breeds in the UK — a large, powerful, intelligent working dog with a long history as a cattle drover, cart-puller, and guard dog in Rottweil, Germany. Their confidence, loyalty, and deep bond with their family make them outstanding companions for experienced owners who understand the responsibility that comes with a large protection breed. Their health profile includes several serious conditions that require proactive screening and awareness.

Health — Key Conditions

Subaortic Stenosis (SAS)

SAS is a congenital heart defect where a ridge of tissue below the aortic valve narrows the outflow tract, forcing the heart to pump harder. In Rottweilers:

  • Can range from mild (detectable murmur only) to severe (fainting, exercise intolerance, sudden death in young dogs)
  • Detected via cardiac auscultation (stethoscope) — a harsh systolic murmur suggests SAS; confirmed by echocardiography
  • Both parents should have cardiac certificates — annual auscultation for breeding dogs is a minimum standard
  • Mild cases are often monitored without treatment; moderate to severe cases benefit from beta-blocker medication

Osteosarcoma (Bone Cancer)

Rottweilers have one of the highest breed-specific rates of osteosarcoma — an aggressive malignant bone tumour:

  • Most commonly affects the long bones (legs), causing lameness, swelling, and pain
  • Metastasis to the lungs is common and often present at diagnosis
  • Treatment typically involves amputation + chemotherapy — three-legged Rottweilers adapt surprisingly well given their muscular build
  • Early detection offers the best prognosis — any unexplained persistent lameness in a Rottweiler, particularly middle-aged and older, warrants prompt investigation including X-ray

JLPP — Juvenile Laryngeal Paralysis and Polyneuropathy

JLPP is a genetic neurological condition specific to Rottweilers, causing progressive nerve damage affecting the larynx (voice box) and limbs:

  • Affected puppies show noisy breathing, voice change, and progressive hindlimb weakness from a few months old
  • DNA test available — both parents should be tested. Carriers are healthy but must only be mated with clear dogs
  • There is no treatment for JLPP — affected puppies have a poor prognosis

Hip and Elbow Dysplasia

Rottweilers are significantly affected by both hip and elbow dysplasia. BVA/KC hip and elbow scoring of both parents is considered a minimum requirement for responsible breeding:

  • The breed median hip score is higher than ideal — ask breeders for scores well below the breed median
  • Elbow scoring uses 0–3 grades — ideally both parents should be grade 0

Temperament

  • Loyal and protective — Rottweilers bond tightly with their family and are naturally territorial. This is a feature, not a fault, but it requires management through thorough socialisation
  • Confident and calm — a well-bred, well-socialised Rottweiler is composed and stable; nervousness or unprovoked aggression are signs of poor breeding or inadequate socialisation, not breed characteristics
  • Highly trainable — intelligent and eager to work; respond excellently to positive reinforcement. Harsh methods create conflict with this strong-willed breed
  • Excellent with children — when properly raised; their size requires supervision with smaller children

FAQs

Are Rottweilers dangerous?

No — Rottweilers are not inherently dangerous. They are a large, powerful protection breed that requires responsible ownership: thorough socialisation from puppyhood, consistent positive training, adequate exercise, and secure containment. A Rottweiler without these elements can become problematic — just as a car without brakes is dangerous while a car with well-maintained brakes is a useful tool. The breed’s negative reputation is driven by irresponsible breeding and ownership, not by breed-inherent aggression. Well-bred, well-socialised Rottweilers are calm, reliable, and devoted family dogs.
