Please see your vet. This guide is general education, not a diagnosis or treatment plan. If your Rottweiler seems unwell, call your veterinarian. If it looks like an emergency, go to an emergency vet right away.

VCA’s Rottweiler overview lists subaortic stenosis among adult health considerations. This guide explains why screening conversations happen—not how to diagnose at home.
Please see your vet for murmurs, fainting, exercise intolerance or breeding decisions.
What SAS is
VCA aortic stenosis describes narrowing at or near the aortic valve; subaortic stenosis (SAS) is the most common form in dogs and is hereditary in certain breeds, including the Rottweiler. Many dogs are identified when a murmur is heard on exam; mild murmurs may be noticed later in puppyhood, while severe disease can show lethargy, breathing effort or syncope.
Screening language
The OFA cardiac disease page outlines registry approaches to heart evaluation for breeding programs. Buyers should request documents they can verify—see responsible breeder or rescue.
Not a treatment plan
Medications, activity limits and specialist referral belong to your veterinary team. Do not start cardiac drugs from an article.
Frequently asked questions
What is subaortic stenosis?
VCA explains that subaortic stenosis (SAS) is the most common form of aortic stenosis in dogs—a narrowing just below the aortic valve. It is hereditary in certain breeds; VCA lists Rottweilers among commonly affected breeds.
What might owners notice?
Many dogs are first flagged when a veterinarian hears a murmur. VCA notes that in moderate to severe disease signs can include lethargy, exercise intolerance, shortness of breath and fainting (syncope). Any of those signs needs prompt veterinary care—this article is not a diagnosis.
How do vets evaluate murmurs?
VCA lists chest radiographs, ECG and echocardiogram (heart ultrasound) among tools used when evaluating aortic stenosis. Your veterinarian decides which tests fit your dog.
What does 'heart screened' mean for breeders?
OFA describes cardiac evaluation programs for breeding dogs. Ask for written results and which protocol was used. Screening reduces uncertainty; it does not make any dog risk-free.
A quick note: this guide is general information from published sources, written by dog lovers, not a veterinarian. Your own vet knows your dog's history, so check with them before changing food, exercise or treatment.
