Echocardiograms for Dogs and Cats

What is an echocardiogram?

An echocardiogram (often called an “echo”) is a non-invasive ultrasound of your pet’s heart. It allows veterinarians to evaluate the heart’s structure and function in real time.

This test is one of the most effective ways to diagnose and monitor heart disease in both dogs and cats.

Why does my pet need an echocardiogram?

An echocardiogram provides detailed information that cannot be seen on X-rays alone. It helps your veterinarian:

  • Assess heart size and shape

  • Evaluate how well the heart is pumping

  • Detect valve abnormalities

  • Identify fluid buildup or congenital defects

This test is commonly recommended if a heart issue is suspected or needs monitoring.

Signs your pet may need an echocardiogram

In dogs and cats:

  • Heart murmur detected during an exam

  • Coughing or difficulty breathing

  • Fatigue or decreased activity

  • Collapse or fainting episodes

  • Rapid or labored breathing

In some cases, pets may show no obvious symptoms, and a murmur is the first indicator.

What to expect during the procedure

Echocardiograms are safe, painless, and typically do not require sedation.

  • Your pet will lie comfortably on their side

  • A small area of fur may be shaved for better contact

  • A probe uses sound waves to create live images of the heart

  • The procedure usually takes 20–45 minutes

Your pet remains awake and comfortable throughout the process.

What conditions can an echocardiogram detect?

Echocardiograms are used to diagnose and monitor a variety of heart conditions, including:

  • Heart valve disease

  • Cardiomyopathy (heart muscle disease)

  • Congenital heart defects

  • Heart enlargement

  • Fluid around the heart

Early detection allows for better management and improved quality of life.

Understanding your pet’s results

Your veterinarian will review the findings and explain what they mean for your pet’s health.

Depending on the results, we may recommend:

  • Monitoring over time

  • Medications to support heart function

  • Referral to a veterinary cardiologist if needed

When should your pet have an echocardiogram?

We may recommend an echocardiogram if your pet:

  • Has a newly detected heart murmur

  • Is showing signs of heart disease

  • Has a known heart condition that needs monitoring

  • Is a senior pet or a breed predisposed to heart issues
