This post is going to look at exercising dogs with a heart murmur.
Grade 1 heart murmurs are common in medium-large breed dogs under five years of age. They are not harmful to your pet but should be monitored regularly by your vet.
If the grade 1 murmur progresses into a more serious condition, it can cause long term damage to the dog’s heart. A veterinarian may prescribe medication to help control heart conditions.
This does not mean that you cannot exercise your dog, but taking precautions such as avoiding steeper hills, not running and reducing ball chasing will help to ensure your pet receives the right amount of exercise.
Keep reading to find out everything you need to know about heart murmurs and the best exercises you can do with your dog if they have a canine heart murmur.
What is a Heart Murmur in Dogs?
A heart murmur is an abnormal sound caused by turbulent blood flow. Your vet will be able to hear it when using a stethoscope to listen to a dog’s heart. There are different types of heart murmurs, some of which are more serious than others; depending on the underlying condition causing the murmur, they may or may not be treatable.
The sound can result from a leaky heart valve, congenital heart defects, weak muscles, heartworm tumours, infections etc. which can only be determined with diagnostic testing and chest x-rays.
Heart murmurs in dogs are not a disease; they’re a symptom, and while it could mean your pooch has an underlying heart problem, such as dilated cardiomyopathy or mitral regurgitation, it can also be completely innocent.
Grades of heart murmurs and what they mean
Young puppies can sometimes develop what are called innocent murmurs; these usually occur at a very young age, resolve given time and are not associated with any underlying heart conditions. If they don’t, you may be referred to a veterinary cardiologist to seek the underlying problem.
Signs Your Dog May Have Heart Disease
Many dogs diagnosed with heart murmurs don’t need any treatment and go on to live a normal life; however, it’s time to visit your veterinarian if you notice any of these symptoms.
- Abnormal heart sound
- A persistent cough
- Excessive panting
- Tires easily during play or exercise
- Shortness of breath
- Lack of energy and reluctance to go on walks
- Rapid breathing

Dog heart murmur treatment
Heart murmurs require regular monitoring. Your vet will try to determine the underlying cause with blood tests, x-rays and/or a heart scan to measure the heart’s size. They will then either recommend a change in your dog’s diet and exercise routine or prescribe medication if needed.
Some are treated with surgery, especially if a birth defect causes them.
Does a heart murmur mean your dog will develop congenital heart disease?
Not necessarily unless it is a continuous murmur, these are most often caused by Patent Ductus Arteriosus, a congenital disease that commonly affects certain breeds such as:
- German Shepherds
- Yorkshire Terriers
Dog heart murmur life expectancy?
A dog with a mild murmur may live as long as any other pooch, but if it progresses to congestive heart failure, it can vary depending on other health factors and the seriousness of the condition; some live for only a few months whilst others live for several years.
