Breathing problems/fast breathing in rabbits


  • Is your rabbit breathing noisily or faster than usual? Are they sneezing? Do they have discharge coming from their nose and/or eyes? Any of these symptoms could indicate a problem with their lungs or airways.
  • Infections, an allergy, passive smoking, heart disease and tumours are all conditions that cause breathing problems in rabbits.
  • Pain can also cause fast breathing.
  • Book an emergency appointment with your vet if you are worried about your rabbit’s breathing. Never wait to see if they improve, left untreated a breathing problem could become much worse, or even be fatal.
  • Take great care with your rabbit if they are having trouble breathing, stress could make the problem worse and in severe cases, even cause death.

General information

Breathing issues in rabbits tend to be serious because:

  • Rabbits are unable to breathe through their mouth, which means a bunged-up nose can make breathing extremely difficult.
  • Rabbits instinctually hide signs of illness to protect themselves, meaning problems often go unnoticed until they are very serious.

What’s normal?

A normal, healthy rabbit should take 30-60 breaths per minute (when calm). They should have a clean nose, clear eyes without discharge and breathe almost silently with no real effort.

Symptoms to look out for

If your rabbit is having trouble breathing, you may notice:

  • Fast breathing
  • Noisy breathing
  • Sneezing
  • Wheezing
  • Weepy eyes
  • A mucky nose (or mucky front paws/legs from cleaning)
  • Reduced appetite
  • Being quiet/withdrawn
  • They may put more effort into breathing than usual meaning you see their abdomen move when they breathe.
