Resting Respiratory Rate Tracker
The single most important thing you can do at home to monitor your dog's heart condition.
Why track?
A rising resting respiratory rate is often the first sign that heart failure is worsening - sometimes days before other symptoms appear. Catching it early means your vet can adjust treatment before a crisis.

Why the resting breathing rate is the number that runs everything
Resting respiratory rate — RR in most clinical notes, sometimes SRR for sleeping respiratory rate — is the piece of advice owners of cardiac dogs give each other more unanimously than any drug, diet or test. It costs thirty seconds, it costs nothing, and it is the only meaningful cardiac measurement you can take at home without equipment.
Cardiologists care about it because the rate climbs when fluid starts collecting in the lungs, and it climbs before the visible symptoms arrive. In owner reports and in the veterinary literature on home monitoring, it rises days ahead of a cough, ahead of exercise intolerance, ahead of the restlessness at night. The cough is a late arrival — and it is, agonisingly, the thing most owners are watching for. A pattern that repeats in the community is the dog treated for kennel cough for three weeks while the actual problem was fluid.
The second thing owners report is less clinical and just as real: counting gives the anxiety a job. Watching a number is more bearable than watching for doom.
How to count it correctly
The details are what turn this into a measurement rather than a guess. Five of them matter.
- Your dog has to be asleep. Not resting. Not lying down watching you. Asleep. A dog who is awake and tracking the room is breathing faster than a sleeping one, and the numbers are not comparable.
- No panting, ever, in a count. Panting invalidates the reading completely. Nothing after a walk, nothing in a hot room, nothing when the dog is excited or stressed.
- One breath is one full in-and-out. Watch the chest or the flank and count the rise and fall as a single breath, not two. Counting the rise and the fall separately is the most common way owners accidentally double their own numbers.
- Count 30 seconds and double it. Thirty seconds is long enough to be stable and short enough that the dog usually stays asleep for it. The timer in the tracker above does the arithmetic for you.
- Keep the conditions the same. A sleeping dog in a cool bedroom at 6 a.m. and a dozing dog on a sunny rug at 2 p.m. are not the same animal. Pick a slot and stay in it.
Learn the baseline before you need it
The number only means something once you know your own dog's normal. A dog whose baseline is 18 and who has run 26 for three nights is telling you something, even though 26 is entirely fine on paper. That is the argument for starting before anything is wrong: you cannot detect a change from a baseline you never established. A week or two of counts is usually enough to see where your dog normally sits.
How to interpret the number
Under 30 breaths per minute is the general benchmark cardiologists cite for dogs at rest, drawn from published work on healthy dogs and on dogs with stable heart disease. Most healthy dogs sit between 15 and 30.
The thresholds owners are usually given
15–30 breaths a minute — the range most healthy sleeping dogs fall into. Keep logging.
Sustained above 35–40 — the threshold most cardiologists set with owners of a dog already diagnosed, and the point at which they want a phone call rather than a wait-and-see.
Above 60 — treated as an emergency, particularly alongside visible effort: neck extended, elbows splayed, belly heaving. That is an emergency clinic, now.
These are the figures commonly used in practice, not a rule for your dog. Ask your veterinarian for the specific threshold they want you to use, and for what they want you to do when it is crossed.
A single high count is not an emergency in itself. Dogs dream, dogs run in their sleep, dogs have one strange night. What matters is the trend: a sustained rise across several counts, or a rate that jumps well past baseline and stays there. That is exactly what the chart in this tool is for — six weeks of readings can be read in seconds as a line, and not at all as ninety text messages to yourself.
Mistakes owners make
- Counting a dog who is merely lying down. This inflates readings and produces false alarms, which then make real changes harder to trust.
- Counting after activity or in a warm room. Heat and exertion both raise the number for reasons that have nothing to do with the heart.
- Panicking at one reading. One number is noise. Recount later before reacting, unless the dog also looks unwell or is breathing with visible effort — in which case the reading is not the point and the vet is.
- Only starting after a diagnosis. A baseline collected while the dog is well is worth far more than one collected during the week you are already worried.
- Logging into a notes app as a pile of numbers. A trend you cannot see is a trend you will miss. Chart it, or use a sheet with the readings in a column.
- Never asking what your own threshold is. Most cardiologists will set a personal number with you at the appointment if you ask. Very few volunteer it.
Bringing the numbers to the appointment
The export button in the tracker produces a plain text log you can email or hand over. A cardiologist reads six weeks of owner monitoring in a few seconds when it arrives as a trend, and it changes the conversation from “he seems more tired lately” to a dated record. If you would rather do this on paper — and plenty of people prefer a sheet on the fridge — the printable Heart Dog Tracker Pack includes a breathing rate log with a baseline box at the top, alongside a medication schedule and an emergency card.
Questions owners ask
What is a normal respiratory rate for a dog at rest?
Most healthy dogs sit somewhere between 15 and 30 breaths per minute while genuinely asleep, and under 30 is the general benchmark cardiologists cite for dogs at rest. Size, age and breed all shift where an individual dog lands inside that band, which is why your own dog's established baseline is more informative than the range itself.
How do I count my dog's breathing rate?
Wait until your dog is fully asleep, watch the chest or the flank, and count one full rise and fall as a single breath. Count for 30 seconds and double the number. Panting invalidates the count entirely, so avoid counting after a walk, after excitement, or in a warm room.
My dog's resting respiratory rate is 40. Should I go to the emergency vet?
A single reading is not a diagnosis, and one odd night happens. What veterinarians act on is a sustained pattern. A rate that stays above 35 to 40 across several counts in a dog already diagnosed with heart disease is the point most cardiologists ask to hear from you, and a sustained rate above 60 with laboured breathing is treated as an emergency. Your veterinarian sets the number that applies to your dog — ask for it explicitly.
How often should I count my dog's breathing?
Once a day is the usual cadence for a dog with a diagnosis, twice a day in the period right after a medication change, and roughly weekly is enough to build a baseline in a healthy dog who is only at risk by breed. Consistency matters more than frequency — the same time, the same room, the same conditions.
Does panting count as breathing rate?
No. Panting is thermoregulation, not resting respiration, and a panting dog can easily run past 100 breaths per minute while being completely fine. If your dog starts panting mid-count, discard the reading and try again later when he is asleep and cool.
Can a rising breathing rate predict congestive heart failure?
It is the earliest home-monitored signal most owners have. The rate rises as fluid begins to collect in the lungs, and both owner reports and the veterinary literature on home monitoring describe it climbing days before a cough, before exercise intolerance, and before night restlessness appear. That is the whole reason cardiologists ask for it: the cough is a late arrival, and a rising number buys back time.
