My dog is breathing fast, is it an emergency?
Updated By PetymFacts checked against official sources on
Quick answer
It depends on when and how. Panting after exercise or in the heat that settles within minutes of rest in a cool place is normal. Fast breathing at rest, noisy breathing, a stretched-out neck, pale, blue or grey gums, or collapse is an emergency: keep your dog calm and cool and go to a vet now.
If your dog seems well otherwise, count the breaths while it sleeps. A university cardiology service says the normal sleeping rate should stay below 30 to 35 breaths a minute. A rate that keeps climbing above that, or fast breathing with heat, ticks, a poison or pain, needs a vet the same day.
What should you do right now?
PDSA calls struggling to breathe a life-threatening emergency. These are the cases that cannot wait.
If Gums or tongue look pale, blue or grey, or your dog has collapsed
Go to the nearest vet now and phone on the way so they are ready. Keep your dog calm and cool: stress makes breathing worse. PDSA
If Your dog may have something stuck in its mouth or throat
Look, and remove the object only if you can see it and reach it easily. Then go to the vet. PDSA
If Heavy panting, thick drool and weakness after heat or exercise
Treat it as heatstroke: move your dog out of the heat, cool the body with water and go to a vet straight away. Merck Veterinary Manual
If A flat-faced dog is gasping, snoring loudly or breathing with its mouth open at rest
Keep it cool and still and call the vet now. Cambridge's BOAS group says a blue tongue or gums, collapse or heatstroke signs need immediate care. University of Cambridge, Department of Veterinary Medicine
If Your dog stops breathing
Start CPR if you have learnt it and get to a vet at once. PDSA links to CPR guides for dogs. PDSA
Is my dog's fast breathing normal?
Ask what your dog was doing, whether it settles, and what else you can see.
If It started after a walk, play or in a hot room, and settles within minutes of rest in shade with water
Usually normal panting, which is how dogs cool down. Walk at cooler times and keep water out. RSPCA (England and Wales)
If It started with crackers, thunder or a stranger, with yawning, hiding or pacing
Fear can cause excessive panting. Comfort your dog in a quiet room and call the vet if it does not settle or your dog vomits or collapses. RSPCA (England and Wales)
If It eased once your dog calmed down, but it was faster or noisier than usual
Probably not an emergency, but PDSA still advises a check-up. PDSA
If Your dog is breathing fast while lying still or asleep in a cool room
Count the breaths (see below) and call your vet today. Fast breathing at rest is not panting to cool down. University of Missouri Veterinary Health Center, Cardiology Service
If It comes with loud noise, a stretched neck, open-mouth breathing or odd gum colour

How do you count a dog's breathing rate?
Count while your dog is asleep or resting quietly, not after play.
The University of Missouri's veterinary cardiology service gives a simple method. Watch your dog while it is sleeping or resting comfortably in a room that is neither hot nor cold. Count the breaths in 15 seconds, where one breath is the chest rising and falling once, and multiply by four to get breaths per minute. It says the normal sleeping rate should stay below 30 to 35 breaths a minute.
For a dog already being watched for heart disease, the same service asks owners to call if the resting rate rises 20 to 30 percent or more above its usual level for three days in a row, or stays above 35 a minute. You do not need a heart diagnosis to use the method: knowing your dog's normal sleeping rate on a calm day gives you and your vet a baseline to compare against. Note it on your phone with the date. One number is never a diagnosis, though: Merck warns that breathing rate also changes with stress and fear.
What makes a dog breathe fast?
Some causes are harmless. Others are emergencies that look the same at first.
| What else you may see | How urgent | |
|---|---|---|
| Heat or exercise RSPCA (England and Wales) | Panting that settles with rest, shade and water | Normal if it settles quickly |
| Heatstroke RSPCA (England and Wales) | Heavy panting, sticky drool, red gums, weakness, vomiting, stumbling | Emergency: cool first, then the vet |
| Fear and stress RSPCA (England and Wales) | Excessive panting and yawning, hiding, pacing, during crackers or storms | Usually settles; vet if it does not |
| Pain Merck Veterinary Manual | A change in breathing, with hiding, restlessness or guarding one area | Same-day vet |
| Flat face (BOAS) University of Cambridge, Department of Veterinary Medicine | Snoring and snorting, open-mouth breathing, overheating on exercise, pauses in breathing in sleep | Vet now if gums turn blue or the dog collapses |
| Anaemia from tick fever Tropical Council for Companion Animal Parasites | Pale gums, weakness, dull and off food, after ticks | Vet now |
| Onion or garlic poisoning Merck Veterinary Manual | Weakness, pale or yellow gums, dark urine and fast breathing, often days after eating | Vet now |
| A human painkiller swallowed Merck Veterinary Manual | Vomiting, lethargy, a swollen face or paws and fast breathing | Vet now |
This table is for deciding how fast to act, not for diagnosis. Only a vet's examination can find the cause.
Why does this matter more in an Indian summer?
Dogs lose heat mainly by panting, and the RSPCA counts dogs with breathing problems, puppies and older dogs among those most at risk of heatstroke. In a humid Indian May or a monsoon week, panting works less well, so a dog left in a hot flat during a power cut, or walked at noon, can move from normal panting to heatstroke quickly. Merck adds that short-nosed dogs can overheat from excitement or stress even on cool days.
Two other Indian patterns matter. Tick fever is common, and TroCCAP lists pale gums and profound weakness among the signs of babesiosis, a parasite of the red blood cells: a dull dog that breathes fast after a tick season needs a blood test, not a wait. And during Diwali the RSPCA's signs of fear, excessive panting and yawning, will look like a breathing problem in many dogs. Fear panting usually eases in a quiet room; fast breathing that carries on after the noise stops does not.

Questions owners ask
How fast should a dog breathe when sleeping?
- The University of Missouri's veterinary cardiology service says a dog's normal sleeping breathing rate should stay below 30 to 35 breaths a minute. Count the breaths for 15 seconds while your dog sleeps in a comfortable room and multiply by four. A rate that keeps rising above that, especially over a few days, is a reason to call your vet.
Why is my dog breathing fast while resting?
- Fast breathing at rest is not normal cooling, so it needs a vet. Causes include pain, heat that has not been shed, anaemia from tick fever, a swallowed poison, heart or lung disease and, in flat-faced breeds, a narrowed airway. Watch the gums: pale, blue or grey gums, or collapse, mean going to a vet now.
Is my dog panting because it is hot or because it is ill?
- Panting from heat or exercise settles within minutes of rest in shade with water. Panting that carries on in a cool room, comes with thick drool, weakness, vomiting or stumbling, or starts without any heat or exercise needs a vet. In heat, the RSPCA's advice is to cool your dog first and then go to the vet.
My dog is panting at night. Should I worry?
- Check the room first: a hot flat during a power cut is a common reason. If the room is cool and your dog is still breathing fast while lying down, count the rate and call your vet. Restlessness, pacing or panting at night can also be signs of pain, which Merck lists as a change in breathing.
Can I give my dog something at home for breathing trouble?
- No. Do not give human medicines: a vet must find the cause first, and human painkillers can themselves cause fast breathing and poisoning in dogs. Keep your dog calm and cool, check for anything stuck in the mouth only if you can see it, and phone the vet on the way.
