Yes — a rabbit that is struggling to breathe is always an emergency. Rabbits breathe through their nose almost exclusively, so open-mouth breathing is a sign of severe distress. Fast, laboured, or noisy breathing can mean pneumonia, heart disease, heatstroke, or pain — all of which need immediate care. Get to an emergency or exotic vet now, and keep your rabbit as calm and cool as possible on the way.
## Why breathing trouble is so serious in rabbits A rabbit at rest breathes quietly through its nose, roughly 30–60 breaths a minute, with little visible body movement. Because rabbits are obligate nasal breathers, a rabbit breathing through its mouth is in serious trouble. Respiratory disease in rabbits (often "snuffles," a Pasteurella infection) can progress to pneumonia, and stress alone can push a compromised rabbit into a crisis.
## Signs it is an emergency - Open-mouth breathing, or breathing with the head and neck stretched out. - Fast, heaving, or exaggerated belly movements with each breath. - A blue or grey tinge to the lips, gums, or tongue. - Nostril flaring, wheezing, or gurgling sounds. - Breathing trouble in a hot environment — suspect heatstroke and cool immediately.
## Handling matters Stress can be fatal to a struggling rabbit. Minimise handling, keep the room quiet and cool, and transport in a covered, well-ventilated carrier. Do not attempt to give any medication or water into the mouth of a breathless rabbit — it can be inhaled.
Get to a vet immediately if you see any of these
- Open-mouth breathing
- Blue, grey, or pale lips, gums, or tongue
- Breathing with an outstretched neck or heaving flanks
- Collapse, floppiness, or unresponsiveness
- Laboured breathing in a hot room (possible heatstroke)
Common questions
How can I tell normal fast breathing from an emergency?
A frightened rabbit may briefly breathe fast but settles when calm, still breathing through the nose. Breathing that stays laboured, uses the mouth, or comes with a colour change to the gums is an emergency.
My rabbit is sneezing and has a runny nose — is that an emergency?
Mild sneezing with clear discharge should be seen by a vet soon, but active breathing difficulty is a step up to emergency. Snuffles can progress to pneumonia, so don't leave it long.
Could a hot day cause this?
Yes. Rabbits tolerate heat poorly and cannot pant effectively. Laboured breathing on a warm day may be heatstroke — start cooling and get emergency help.
