Breathing trouble in a pet is a red-flag symptom. If your pet is struggling to breathe, don't wait. Head to the nearest emergency clinic.

If your pet has trouble breathing, collapses, cannot urinate, has an ongoing/repeated seizure or may have swallowed poison, call an emergency veterinary clinic immediately. Do not wait for an online consultation or for paperwork.

Signs of labored breathing

  • Open-mouth breathing in cats, which is never normal at rest
  • Belly or chest heaving with each breath
  • Flared nostrils or noisy, raspy breathing
  • Stretching the neck out or sitting with elbows out
  • Refusing to lie down
  • Blue, gray or pale gums
  • Coughing, gagging or wheezing

Count your pet's resting breaths per minute while they sleep. Counts above about 30 are worth a call to your vet.

Possible causes

Heart disease, fluid in or around the lungs, asthma (especially in cats), pneumonia, airway disease, heatstroke, allergic reactions, trauma and toxins can all cause breathing trouble. Flat-faced breeds are especially prone to airway problems.

What to do right now

  1. Stay calm and keep your pet quiet, since stress worsens breathing.
  2. Keep them cool and in fresh air.
  3. Don't force food, water or medication.
  4. Call ahead to an emergency clinic and go straight there.

Why speed matters

Breathing problems can worsen fast, and early treatment often makes a major difference. To locate care quickly, find a nearby veterinarian.

Less urgent breathing changes

New, worsening or noisy breathing needs veterinary assessment. Flat-faced pets are at particular risk; do not dismiss breathing difficulty as normal for their breed.

FAQs

Is fast breathing always an emergency?

Not always, since heat, excitement and exercise can cause it. If breathing stays fast at rest, ask a vet.
