My rabbit is breathing fast - what is normal and what is not?
A resting, calm rabbit breathes roughly 30 to 60 times a minute. Count the chest rises for 15 seconds and multiply by four. Anything sustained above that at rest, and any open-mouth breathing, is an emergency: rabbits breathe through the nose by necessity, so open-mouth breathing or blue-tinged gums is described in veterinary texts as a poor prognostic sign. Heat, pain and fear all raise the rate, so cool and quiet first, then count again.

What to do in the next hour
- Count breaths for 15 seconds while your rabbit is resting and undisturbed, then multiply by four. Write the number and the time down.
- Move the rabbit somewhere cool, shaded and quiet. Heat alone drives a high rate.
- Look at the mouth and nostrils without restraining. Open-mouth breathing, a snotty nose, or noise on each breath all mean go now.
- Call a rabbit-seeing vet or emergency clinic and read out the rate you counted.
- Film 10 seconds from the side, at rest, so the chest and nostril movement is visible.
- Do not restrain, wrap or carry the rabbit around while it is struggling to breathe. Transport it in a well-ventilated carrier with hay.
Breathing rate at rest, and what it means
Counted while the rabbit is calm and resting, not after handling or a chase. Reference range from the UC Davis veterinary emergency team vital signs chart.
| Breaths per minute at rest | What it suggests | What to do |
|---|---|---|
| 30 to 60 | Published normal range for a calm adult rabbit | Normal. Recount if posture or appetite changes |
| 60 to 90 | Raised. Often heat, stress or early pain | Cool and quiet the room, recount after 20 minutes, call a vet if it stays up |
| Over 90 at rest | Respiratory or cardiac effort, pain or heat stress | Vet today, and now if anything else on the urgent list is present |
| Any rate with open mouth breathing | Rabbits breathe through the nose by necessity, so this is severe | Emergency. Go immediately |
| Any rate with blue or grey gums | Oxygen is not getting through | Emergency. Go immediately |
When to see a vet today
See a vet today if you notice Open-mouth breathing, or breathing with the head and neck stretched out, Blue, grey or very pale gums or tongue, and Noise on every breath, or nostrils flaring hard with each breath. These are the signs that should not wait for home care or a watch-and-see approach. If any of them appear, skip the rest of this guide and call your vet or an emergency clinic now - waiting is the risky option.
- ●Open-mouth breathing, or breathing with the head and neck stretched out
- ●Blue, grey or very pale gums or tongue
- ●Noise on every breath, or nostrils flaring hard with each breath
- ●Resting rate sustained well above 60 breaths a minute once the rabbit is cool and calm
- ●Fast breathing with hunching, no droppings, or refusal of food
- ●A hot rabbit, damp around the nose and mouth, in warm weather
Safe to monitor at home
Milder signs are usually safe to watch for a day or two: A brief rise straight after handling, a chase or a nail trim, settling within minutes, Slightly raised rate on a warm afternoon that returns to normal once the room cools, and Occasional single sneezes with clear nostrils, normal appetite and normal droppings. Keep notes and photos so you can spot a trend. Anything that worsens, spreads, or comes with appetite, energy or behavior changes moves out of this category and into a vet visit.
- ●A brief rise straight after handling, a chase or a nail trim, settling within minutes
- ●Slightly raised rate on a warm afternoon that returns to normal once the room cools
- ●Occasional single sneezes with clear nostrils, normal appetite and normal droppings
What to photograph or record
Photograph or record Film 10 seconds from the side, at rest, showing the chest and the nostrils, Photograph the nostrils and front paws, since rabbits wipe their nose with the paws and discharge shows there, and Photograph the gums if you can lift the lip without a struggle in good, even light. Clear, well-framed evidence is what lets a vet - or a PetLumen scan - judge the change instead of guessing from a description. The checklist below is the exact shot list.
- Film 10 seconds from the side, at rest, showing the chest and the nostrils
- Photograph the nostrils and front paws, since rabbits wipe their nose with the paws and discharge shows there
- Photograph the gums if you can lift the lip without a struggle
- Write down the counted rate, the time, and the room temperature
- Note any coughing, noise or discharge, and when it started
Likely causes
The causes vets consider first for this presentation are heat stress, lower respiratory infection, upper airway disease, and pain. Most are manageable once identified, but they look similar from the outside, which is why a photo-based triage and, when needed, an exam matter more than guesswork.
Heat stress
Rabbits cope badly with heat and cannot pant efficiently. A high rate on a warm day with a flat, damp-faced rabbit is an emergency.
Lower respiratory infection
Pneumonia and bacterial airway disease raise effort and rate. Veterinary texts treat open-mouth breathing or cyanosis in rabbits as a poor prognostic sign.
Upper airway disease
A blocked or snotty nose matters more in rabbits than in dogs because they breathe through the nose by necessity.
Pain
Gut pain, dental pain or a wound will raise the rate. Look for hunching, teeth grinding and a change in droppings alongside.
Heart disease and chest masses
Older rabbits can develop cardiac disease or a thymoma, both of which reduce chest room and raise resting effort.
Fear and handling
Restraint, transport and predators nearby all spike the rate briefly. This is the one cause that settles on its own within minutes.
Safe home care
For mild cases, safe home care is cool the room and shade the enclosure. ceramic tiles and a wrapped frozen bottle placed where the rabbit can choose to lie against it, leave the rabbit undisturbed on the floor while you arrange a vet visit, and keep hay and a water bowl within reach of where it is sitting. These steps comfort and monitor; they do not treat the underlying cause. Stop home care and call a vet if anything in the urgent list above appears or the trend moves the wrong way.
- -Cool the room and shade the enclosure. Ceramic tiles and a wrapped frozen bottle placed where the rabbit can choose to lie against it
- -Leave the rabbit undisturbed on the floor while you arrange a vet visit
- -Keep hay and a water bowl within reach of where it is sitting
- -Transport in a ventilated carrier with hay, and keep the car cool
- -No nebulising, steam or human decongestants unless a vet has prescribed them
- -No restraint to look in the mouth if the rabbit is fighting you

When it is not an emergency
Not every worrying sign needs an out-of-hours visit. These situations are usually safe to watch at home, as long as eating, drinking and droppings stay normal and nothing in the urgent list above appears.
- ●Rapid breathing that settles to under 60 within a few minutes of being left alone after handling
- ●A faster rate during a car journey or a vet visit, which is fear rather than disease
- ●Visible nostril movement in a rabbit that is otherwise eating hay, alert and producing normal droppings
- ●A single sneeze after digging in fresh hay, with clear nostrils and no discharge
Frequently asked
What is a normal breathing rate for a rabbit?
About 30 to 60 breaths a minute in a calm, resting adult rabbit, per the UC Davis veterinary emergency team vital signs chart. Count chest rises for 15 seconds and multiply by four.
Why is open-mouth breathing so serious in rabbits?
Rabbits breathe through the nose by necessity, so a rabbit resorting to its mouth has run out of easier options. Veterinary rabbit texts describe open-mouth breathing or blue-tinged membranes as a poor prognostic sign, which means emergency care now.
Can heat alone make my rabbit breathe fast?
Yes, and it can kill. Rabbits tolerate heat poorly. Cool the room and shade the enclosure immediately, and treat a flat, fast-breathing rabbit in warm weather as an emergency rather than a hot afternoon.
My rabbit only breathes fast when I pick it up. Is that a problem?
A short spike from handling that settles within a few minutes is normal fear. A rate that stays high after ten quiet minutes on the floor is not.
Should I count the rate before I call?
Yes if it takes under a minute. A real number gives the clinic far more than the word fast, and it tells you whether cooling and quiet actually helped.
