Why Cardiology Matters

Heart problems can affect a pet’s breathing, energy, and overall quality of life.

Early detection and proper diagnosis are essential to keep your pet comfortable and safe, especially if you’ve noticed coughing, weakness, or changes in activity.

When to Schedule a Cardiology Exam

You should book a heart evaluation if your pet has any of the following:

  • Heart murmur
  • Irregular heartbeat
  • Breathing difficulty or rapid breathing
  • Exercise intolerance
  • Weakness or fainting episodes
  • Persistent coughing
  • Abnormal heart sounds noted by a veterinarian

These symptoms may indicate an underlying heart condition that needs attention.
