Hearing that your dog has a heart murmur can be scary and confusing. You may be wondering what it means for your pup’s health, whether it’s serious, and what you should do next. The good news is that heart murmurs are a common finding, and not all of them are life-threatening. Let’s break it down step by step so you can feel confident about your dog’s care.
⚠️ What to Watch For
Heart murmurs are abnormal sounds in your dog’s heartbeat, often described as a “whooshing” noise instead of the usual “lub-dub.” While many murmurs are harmless, others may indicate underlying heart disease. Here’s what to look for:
- Fatigue or reduced energy during play or walks
- Coughing, especially at night or after activity
- Difficulty breathing or rapid breathing
- Fainting or collapsing
- Pale or bluish gums
In some cases, your dog may show no outward symptoms, and the murmur is only detected during a routine vet checkup.
🔍 Possible Causes
Heart murmurs can be caused by a variety of factors, ranging from harmless to more serious. Here are some common causes:
- Innocent murmurs: These are benign and often found in young puppies. They typically resolve as the puppy grows.
- Congenital defects: Some dogs are born with structural abnormalities in their hearts, such as a hole in the heart or valve deformities.
- Valve disease: Common in older dogs, this occurs when heart valves become leaky or don’t close properly.
- Heart enlargement: Conditions like dilated cardiomyopathy can cause the heart to struggle with pumping blood effectively.
- Anemia: Low red blood cell counts can lead to murmurs because the blood flows differently through the heart.
Your vet may classify the murmur based on its intensity (graded on a scale of 1 to 6) and whether it’s related to a specific part of the heart. This helps determine its significance and guide further testing.
✅ What You Can Do at Home
While some cases require medical intervention, there are steps you can take at home to support your dog’s heart health:
- Feed your dog a balanced, high-quality diet that supports heart health.
- Keep your dog at a healthy weight to reduce strain on their heart.
- Provide regular, moderate exercise unless your vet advises otherwise.
- Monitor your dog for any changes in behavior, energy levels, or breathing.
These small actions can make a big difference in maintaining your dog’s overall well-being and quality of life.
💡 When to Call a Vet
If your dog has been diagnosed with a heart murmur, follow your veterinarian’s recommendations for further testing. In some cases, additional diagnostics like X-rays, an echocardiogram (heart ultrasound), or blood work may be necessary to determine the underlying cause.
You should contact your vet immediately if your dog shows any of the following signs:
- Severe difficulty breathing
- Sudden collapse or fainting
- Swollen abdomen (a sign of fluid buildup)
- Reluctance to eat or severe lethargy
These symptoms could indicate heart failure or a worsening condition that needs urgent attention.
