How to Care for a Dog with Heart Murmur

For many dogs, it will not be apparent to an outsider that your dog has a heart murmur. Many dogs with a heart murmur can go on to live long and happy lives. You’ll still be able to take your dog for walks, bring them to the park, and go about your everyday life.

Some heart murmurs will disappear on their own, while others will constantly be around, but not affect the quality of life you and your dog can have. There will just be additional things to monitor if your dog is diagnosed with a heart murmur.

What to do if your dog has a heart murmur:

  • Monitor your dog’s fatigue levels
  • Pay attention to coughing
  • Listen for shortness of breath
  • Schedule routine veterinary visits

As with many health conditions, it is important to monitor your dog’s fatigue levels. You want to ensure your dog is getting proper exercise but you also need to be cognizant of how your dog is responding to the exercise.

If your dog appears to be getting fatigued during a longer than normal walk, that’s pretty normal. Just keep a close eye to make sure nothing else changes. And then plan on taking a shorter walk next time.

Additionally, if your pup is fatigued shortly into your normal exercise routine or earlier than normal, you should reach out to your veterinarian to make sure your dog’s condition has not gotten worse or to make sure this is not a symptom of an additional health condition.

If you are aware of a heart murmur diagnosis in your furry friend and you hear them start coughing, this could be a sign that the condition is getting worse.

The cough could just be something as simple as a cold but it could be an early sign of congestive heart failure. If your dog starts coughing, be sure to call your veterinarian and schedule an appointment.

Just like with the coughing, shortness of breath, or difficulty breathing is a sign that your dog may have congestive heart failure. If your dog is experiencing this, you should bring your dog in immediately.

Routine veterinary visits will help keep tabs on your dog’s health. It allows your veterinarian to see how they are progressing and make that the murmur is not getting worse. This is also just a good routine to get into since dogs age much faster than people. It is recommended that dogs see their veterinarian bi-annually.

How to Monitor and Detect Heart Murmur in Dogs

It’s always important to pay close attention to your dog’s behavior. Any changes in your dog’s behavior can be a sign that your dog is experiencing a health condition.

Although not all dogs with a heart murmur will show symptoms. Sometimes the only way to detect a heart murmur is through routine veterinary visits. Even so, it’s important to keep an eye on any potential symptoms so you can call your veterinarian to schedule an appointment if you see something alarming.

Signs your dog has a heart murmur:

  • Difficulty breathing
  • Coughing
  • Swollen abdomen
  • Fainting
  • Exercise intolerance

Keep an eye on your dog’s breathing. If your dog starts to have difficulty breathing or shortness in breath, you will want to talk to your veterinarian to determine if your dog has a health condition.

Breathing issues could mean a disease of the lungs, airways, space around the lungs, throat and windpipe, nose, chest wall, or diaphragm. This could be a sign of heartworm disease or heart failure.

A cough can be a sign of many different problems. Some dogs will develop canine cough or kennel cough, a contagious viral or bacterial infection. This cough tends to be deep and dry. It is typically found in dogs who have been boarded recently or who have been in contact with a large number of dogs.

Dogs can have a gagging cough which can mean your dog has a sore throat or tonsillitis. A gagging cough can also mean something is stuck in your dog’s throat. Your dog’s cough could be more of a wet cough which means there may be a build up of fluid or phlegm in the lungs.

This is typically pneumonia. And a cough could be a sign of congestive heart failure. To be safe, it’s best to contact your veterinarian if your dog starts coughing.

There are many reasons why your dog may have a swollen abdomen and many of the reasons can be life-threatening. If you notice a swollen abdomen, call your veterinarian as soon as possible.

This may happen if your dog has gastric dilation volvulus, meaning your dog’s distended stomach has rotated, trapping gasses inside and block the stomach’s blood supply.

Another cause for stomach swelling is peritonitis, or a puncture in your dog’s stomach or small intestine. Another cause could be ascites, or accumulation of fluid in the abdomen. This could be due to heart failure.

If your dog faints, this could be a sign of many different health conditions. It is important to see if you can feel a heartbeat after the dog faints so you can help your veterinarian determine what the cause of fainting is.

Pay attention to if the heart rate is slow or rapid. Take your dog in right away to determine what the cause is. Many times, the veterinarian will have to perform an electrocardiogram and perform blood work. Additional testing will be done depending on what the initial tests show. Cushing’s Syndrome is another cause for a swollen belly.

If your dog has an intolerance for exercise, it could be a sign of an underlying health issue. It could be due to heart disease, arthritis, or other diseases. It’s important not to force your dog to exercise and instead listen to what your dog is trying to tell you.

Call up your vet and talk to them about what you are experiencing. They can help you determine if your dog is just being lazy or if there is something wrong with your dog.

How Can I Make Sure My Dog’s Heart Stays Healthy?

There are a lot of proactive things you can be doing to help keep your dog’s heart healthy. A healthy heart can help prevent heart conditions and can help your dog live a long and happy life. Follow the steps below to see what you can do to help keep your dog’s heart healthy.

What to do to keep your dog’s heart healthy:

  • Balanced diet
  • Exercise
  • Regular veterinary exams
  • Dental care
  • Prevent heartworm disease
  • Be cognizant of your dog’s breed
  • Watch for signs of heart irregularities

Feed your dog a healthy, balanced diet. Just like it’s important for humans to eat a healthy, balanced diet, dogs also need a good diet. This is the foundation to having a healthy dog.

A dog’s diet affects their skin, coat, organ function, joints, and everything in between. A balanced diet also helps your dog maintain a healthy bodyweight. If your dog is overweight or obese, this puts extra stress on your dog’s heart.

Make sure to look at the ingredients in your dog food and pick one that is balanced and has high quality products. Keep treats to a minimum.

Exercise can also help keep your dog’s weight in the healthy range. But just because a dog’s weight looks healthy, it doesn’t mean that your dog is healthy. Cardio exercise helps keep the dog’s heart healthy. This exercise can include walking, running, hiking, and swimming.

Since dogs age faster than humans – roughly 4 to 8 years for every 1 human year – it is important to have regular veterinary exams. This will help ensure your dog is healthy and help find any health issues early on.

Many pet owners schedule annual exams but since dogs age so quickly, bi-annual exams are recommended. A lot can happen in one year of a dog’s life.

You may not think dental care has a lot to do with your dog’s heart health, but it does. Plaque and tartar buildup in your dog can lead to an infection in the mouth. This enters the bloodstream and can attribute to heart issues.

Be sure to brush your dog’s teeth regularly and give them bones that help ward off plaque and tartar. And keep an eye out for bad breath, sore gums, excessive drooling, and bleeding. If you see any of those symptoms, contact your veterinarian and schedule an appointment.

Make sure you are giving your dog preventative heartworm medication. If your dog contracts heartworm disease, which is transmitted by mosquitos, it puts a huge strain on your dog’s heart, making it more prone to heart murmurs.

Even after treatment, your dog’s heart may never be the same. It’s easiest to prevent this disease through medications and supplements.

Some breeds are more prone to have heart issues. Be sure to know what health conditions your dog’s breed is prone to having so you can keep a close eye on any symptoms that happen early on.

Understanding your breed also helps you take proactive measures to prevent health conditions. Research your dog’s breed and take proactive preventative measures to keep your dog healthy and help them live a long and happy life.

Keep a close eye on signs of a heart condition. Everyday activities can take a toll on your dog’s body and their heart. Heart issues can develop slowly from old age, an injury, or illness.

Be aware of the symptoms associated with heart conditions and contact your veterinarian immediately if you see any of the symptoms. Symptoms include: difficulty breathing, coughing, fainting, fatigue, and swollen abdomen.

While not all cases of a heart murmur are preventable, if you keep an eye on your dog and follow the above steps, you can help your dog live a long and healthy life. And even if your dog has been diagnosed with a heart murmur, following the above steps can help prolong your dog’s life.
