The short answer
Plan around four things. Bone cancer (osteosarcoma) is the most serious breed risk, so a limp that does not settle in an adult dog needs X-rays, not waiting. Any heart murmur needs a cardiologist’s echocardiogram because of subaortic stenosis. Hips, elbows and cruciate ligaments carry a heavy frame, so keep the dog lean. And bloat is an emergency to recognise on sight. Price pet insurance in your first week.
Bone cancer (osteosarcoma)
VCA Animal Hospitals lists the Rottweiler among the large breeds at higher risk of osteosarcoma, an aggressive bone cancer. It usually starts in the long bones of the legs, and most affected dogs limp on that leg. Swelling over the bone and pain that grows worse can follow.
The practical rule for a middle-aged or older Rottweiler: a limp that does not settle with rest gets X-rays rather than a wait-and-see. When the cancer has not visibly spread, treatment typically means amputating the affected leg, usually followed by chemotherapy. Large dogs often adapt to three legs better than owners expect, because the bone pain is gone. Your vet and a veterinary oncologist guide the options, including comfort-focused care.
Subaortic stenosis (SAS)
SAS is an inherited narrowing just below the aortic valve that makes the heart work harder to push blood out. Cornell’s veterinary college describes it as mainly a large-breed condition that often shows in the first year, and a cardiology practice handout names the Rottweiler among the breeds where it is most often found.
Mild SAS may never cause trouble, while severe cases can cause fainting, exercise intolerance or sudden death in young dogs. The first clue is usually a heart murmur. Any Rottweiler with a murmur, puppy or rescue adult, should see a veterinary cardiologist for an echocardiogram, which is the test that confirms and grades it. It matters before anaesthesia too, so raise it before any planned surgery.

Foster notes often mention a murmur, a limp or weight, which is exactly what to raise at your first vet visit.
See Available Rottweilers →Hips, elbows and knees
Hip and elbow dysplasia are common in heavy, fast-growing breeds: the joint forms loosely and wears into arthritis over time. Torn cruciate ligaments in the knee are another frequent injury in big, muscular dogs. Signs include stiffness after rest, a bunny-hopping gait, reluctance to climb stairs or jump into the car, and sudden lameness on a back leg after play.
Weight is the lever you control. The VCA guidance on hip dysplasia stresses lean growth in puppies, a large-breed growth diet, weight loss for heavy dogs and moderate, low-impact exercise. Your vet can screen hips and elbows with X-rays and discuss management if signs appear.
Bloat (GDV): know the signs
Gastric dilatation-volvulus happens when the stomach fills with gas and twists. It is most common in large, deep-chested dogs and is fatal without fast treatment, so recognise it on sight: unproductive retching, a swollen belly, drooling, restlessness and laboured breathing. VCA is clear that immediate veterinary care is needed, within minutes to a few hours.
A preventive gastropexy, which tacks the stomach to the body wall, prevents twisting in most cases and is sometimes done at the same time as a spay or neuter. Ask your vet whether it suits your dog.
JLPP and eye disease
Juvenile laryngeal paralysis and polyneuropathy is an inherited nerve disease that Embark notes has only been characterized in Rottweilers and Black Russian Terriers. Signs can start around three months: noisy breathing with exercise, a change in the bark and weakness. A DNA test identifies affected dogs and carriers, which is mainly a breeding question but useful context for a young rescue with breathing noise.
Progressive retinal atrophy, a painless inherited loss of vision that usually starts with poor night vision, is another condition VCA lists for Rottweilers. Eyelid problems such as entropion also occur. A squinting, watery or cloudy eye deserves a vet visit.
The first vet visit after adoption
Ask for a careful heart listen (and an echocardiogram referral if there is any murmur), a gait and joint assessment, a body condition score with a written target weight, an eye check and baseline bloodwork. For a senior Rottweiler, add a thorough lump check and a conversation about any limp. Bring the rescue’s intake records.
Price pet insurance the same week. Every Canadian provider excludes conditions documented before enrolment, and this breed’s main risks (cancer, orthopaedic surgery, cardiac care, bloat) are exactly the large, sudden costs insurance exists for. Look for hereditary-condition coverage and a high annual limit, and compare a few providers.
Frequently asked questions
What are the most common Rottweiler health issues?
Bone cancer (osteosarcoma), the heart defect subaortic stenosis, hip and elbow dysplasia, torn cruciate ligaments, bloat, and inherited conditions such as JLPP and progressive retinal atrophy.
My Rottweiler is limping. Should I worry about bone cancer?
Most limps are injuries or joint problems, but in a middle-aged or older Rottweiler a limp that does not settle with rest deserves X-rays rather than waiting, because the breed is at higher risk of osteosarcoma and early diagnosis keeps more options open.
What does a heart murmur mean in a Rottweiler?
It can be harmless, but Rottweilers are among the breeds where subaortic stenosis is most often found. A veterinary cardiologist’s echocardiogram confirms whether it is SAS and how severe it is, and it is worth knowing before any anaesthesia.
How do I recognise bloat?
Unproductive retching, a swollen or tight belly, drooling, restlessness and laboured breathing. It is a life-threatening emergency: go straight to an emergency vet.
How long do Rottweilers live?
Rottweilers generally live shorter lives than small breeds, with cancer a leading reason. Good weight control, early screening and prompt attention to limps, murmurs and lumps give your dog the best odds.
Should I get pet insurance for a rescue Rottweiler?
It is worth pricing in your first week. Canadian pet insurance excludes conditions documented before enrolment, and the breed’s main risks are large, sudden costs. Look for hereditary-condition coverage and a high annual limit.
