Dogs are not just pets, they are part of our family. So, when something seems off, you, as a caregiver, take notice. Today, we’re going to talk about a common canine health issue that might concern you: heart murmurs in dogs.
What Is a Heart Murmur
A heart murmur is an extra or unusual sound heard during a heartbeat. It’s usually characterized by a ‘whooshing’ sound, which is caused by turbulent blood flow in or near your dog’s heart. However, not all heart murmurs are serious. Sometimes, they can be innocent or physiological, not necessarily implying a disease.
Causes of Heart Murmurs
Heart murmurs can be caused by a variety of issues. Here are the most common:
- Congenital Heart Defects: Some dogs are born with heart defects that cause murmurs.
- Heart Disease: Diseases such as dilated cardiomyopathy or degenerative valve disease can lead to murmurs.
- Old Age: As your dog ages, the heart can naturally wear out, leading to murmurs.
- Anemia or High Blood Pressure: Both of these conditions can put extra pressure on the heart, resulting in a murmur.
Symptoms to Look Out For
If your dog has a heart murmur, you might notice the following symptoms:
- Weakness or fatigue
- Difficulty breathing
- Coughing
- Loss of appetite
- Weight loss
These symptoms might not always be present or noticeable. Therefore, regular vet check-ups are crucial.
How Heart Murmurs Are Diagnosed
During a regular check-up, your vet might notice the murmur while listening to your dog’s heart with a stethoscope. If a murmur is discovered, your vet may recommend additional tests such as:
- X-rays: To check for heart enlargement
- Echocardiogram: To see the heart’s structure and function
- Electrocardiogram (ECG): To measure the electrical activity of the heart
| Test | Purpose |
|---|---|
| X-ray | Check for heart enlargement |
| Echocardiogram | Observe heart’s structure and function |
| ECG | Measure heart’s electrical activity |
Managing Heart Murmurs
If your dog has been diagnosed with a heart murmur, don’t panic. Many dogs live long, healthy lives with heart murmurs. Your vet might recommend medication, diet changes, or even surgery in severe cases. The most important thing is to ensure your dog has regular check-ups so any changes can be monitored.
