Why is my dog panting so much?

Symptoms • HealthUpdated 2026

Normal vs. Emergency

Panting is normal for cooling down. However, heavy panting while resting, or combined with pale gums, drooling, or lethargy, can signal pain, fever, or heatstroke.

Common Reasons

  • Heat Regulation: Dogs don't sweat; they pant.
  • Excitement/Stress: Anxiety or happiness can increase breathing rate.
  • Pain: Often overlooked; a dog in pain will pant heavily.

When to See a Vet

If panting is sudden, unprovoked, or accompanied by shaking or reluctance to move.
