Why it matters
Faster breathing at rest can be an early sign of fluid building up in the lungs from heart failure. Vets often ask owners of pets with heart disease to count it at home.
How to count
- Wait until your pet is asleep or deeply relaxed
- Count each rise of the chest as one breath
- Count for 30 seconds and double it
- Record the number and date
What is normal
Most healthy sleeping dogs and cats take fewer than 30 breaths a minute. Your vet will tell you what to watch for in your own pet.
When to call a vet
Call if the rate is repeatedly above your vet's limit, or rising day by day. Open-mouth breathing in a cat, or blue gums, is an emergency.
