🐾 Sleeping Respiratory Rate Counter
Counting your pet's breaths while they sleep is one of the few genuinely useful heart checks you can do at home. Start the timer, tap once for every breath, and get the rate per minute with what it means.
Watch your dog's chest or belly. One breath = the chest rising and falling once. Press Start 30-second count, then tap the big button for every breath.
Why Cardiologists Ask Owners to Count
When heart disease progresses to heart failure, fluid starts to build up in or around the lungs. One of the earliest things that changes is how fast a pet breathes at rest, often before coughing, tiredness or obvious distress. A sleeping pet has none of the usual reasons to breathe fast, so a rise in the sleeping rate is a signal worth acting on.
That is why veterinary cardiologists routinely send owners of dogs and cats with heart disease home with one instruction above all others: count the breaths while they sleep, and call if the number stays up. It costs nothing, takes thirty seconds, and it is the one heart check you can do every day. The thresholds this tool uses follow the owner guidance published by the Cardiac Education Group, a group of veterinary cardiologists.
The Numbers
- About 15–30 breaths a minute is typical for a sleeping or calmly resting dog or cat, with or without heart disease. Lower can be normal in a pet that is otherwise well.
- Consistently above about 30 while asleep is the point to recount and then contact your vet. The same threshold applies to dogs and cats.
- Your pet's own baseline matters as much as the threshold. A dog that usually sleeps at 16 breaths a minute and is now steadily at 27 has changed, even though 27 is "normal".
How to Get an Accurate Count
- Count during real sleep, not the first minute after lying down. Evening, once the house is quiet, is often easiest.
- Watch, don't touch. Look at the chest or belly from a little distance. A hand on the chest often wakes the pet or changes the rhythm.
- One rise plus one fall is one breath. Counting each movement separately doubles the number, the single most common counting mistake.
- Ignore dream breathing. Twitching, paddling or sudden quick breaths during a dream push the rate up. Wait until it settles and count again.
- Cats must not be purring. A purring cat can't be counted accurately.
- Room temperature matters. A pet sleeping in a hot room or in the sun may breathe faster for reasons that have nothing to do with the heart.
When you are learning, count once a day for about a week to find your pet's usual number. After that, follow your vet's schedule. For a pet with diagnosed heart disease, that is often daily.

Frequently Asked Questions
What is a normal sleeping breathing rate for a dog or cat?
Dogs and cats, with or without heart disease, typically breathe about 15 to 30 times a minute when asleep or resting calmly, and lower rates can be normal in a pet that is otherwise well. Veterinary cardiology guidance uses roughly 30 breaths per minute as the point above which a sleeping rate is considered raised. The same threshold is used for both species.
Why count breaths while the pet is asleep?
Because sleep removes almost everything else that changes breathing: excitement, heat, exercise, sniffing, panting and purring. That makes the sleeping rate a stable baseline, so a rise is more likely to mean something. In dogs and cats with heart disease, fluid building up in or around the lungs makes breathing faster before other signs appear, which is why cardiologists ask owners to track it at home.
My pet's breathing rate is over 30. What should I do?
Recount several times over the next couple of hours while your pet is properly asleep, because a single reading can be thrown off by a dream, a recent walk or a warm room. If the rate stays consistently above about 30 a minute, contact your vet, who will usually want to see your pet within a day or two. If your pet has diagnosed heart disease, call the same day. A raised rate together with laboured breathing, pale or bluish gums, collapse, or restlessness and inability to settle is an emergency.
How do I count my cat's breathing if she is purring?
Wait. A purring cat cannot be counted accurately, and veterinary guidance specifically says to count when the cat is not purring. The easiest time is when your cat has been deeply asleep for a while. Watch the side of the chest or belly rather than listening, and count one breath each time the chest rises and falls once.
How often should I check my pet's sleeping respiratory rate?
When you are first learning, count once a day for about a week to establish your pet's own baseline. After that, follow your vet's instructions; for pets with diagnosed heart disease, many cardiologists ask for daily or several-times-weekly counts. What matters most is the trend: a pet whose usual sleeping rate is 18 and is now consistently 28 has changed, even though 28 is still under 30.
