Is my dog breathing too fast while sleeping?
A dog's normal sleeping breathing rate should stay below 30 to 35 breaths per minute. Count while your dog is asleep or resting calmly, not after exercise. Call your vet if the rate is consistently above 35, or rises 20-30% above your dog's normal for three days in a row. Vets often ask for this number in dogs with heart disease.
Frequently asked questions
What is a normal sleeping breathing rate for a dog?
Below 30 to 35 breaths per minute while asleep or resting calmly. Each dog has its own normal, so measure a few times when your dog is well to learn the baseline.
How do I count my dog's breaths?
Watch the chest while your dog sleeps. One rise and fall is one breath. Count for 15 or 30 seconds and multiply to get breaths per minute, or use the tap counter on this page.
When should I call the vet about fast breathing?
If the sleeping rate is consistently above 35, if it rises 20-30% above normal for three days in a row, or right away if breathing looks hard: the chest and belly heave, the neck is stretched out, the legs are spread wide or your dog suddenly prefers to sleep lying on the chest.
Why do vets ask for the sleeping breathing rate?
In dogs with heart disease, a rising sleeping breathing rate can be an early sign of fluid building up, often before other signs appear.
