Monitoring your pet’s sleeping respiratory rate (SRR) is one of the simplest and most powerful tools you can use at home to keep track of their heart and lung health. It’s quick, it’s free, and it gives your veterinary team incredibly valuable information — especially for pets with heart disease, respiratory conditions, or those at risk of developing congestive heart failure.

In the video above, we walk you through exactly how to measure an SRR and explain why this small daily habit can make such a big difference.

What Is a Sleeping Respiratory Rate?

A sleeping respiratory rate is the number of breaths your pet takes in one minute while they are asleep and completely relaxed. This is the most accurate time to measure breathing because excitement, movement, and stress can all temporarily increase the rate.

For most healthy dogs and cats, a normal SRR is under 30 breaths per minute.

How to Measure Your Pet’s SRR at Home

Measuring an SRR is simple — and once you’ve done it a few times, it becomes second nature.

1. Wait until your pet is asleep
   Choose a time when they’re resting deeply, not dreaming or twitching.
2. Watch the chest or belly rise and fall
   One rise + one fall = one breath.
3. Count the breaths for 30 seconds
   Use your phone’s timer for accuracy.
4. Multiply by two
   This gives you the number of breaths per minute.
5. Record the number
   Keeping a daily log helps your vet spot trends early.

If your pet wakes up, moves, or starts dreaming, wait and try again later.

Why Your Vet Wants You to Do This

Changes in sleeping respiratory rate are often the earliest sign that a pet’s heart or lung condition is worsening. Many pets show no outward symptoms until their disease has progressed — but their SRR will quietly increase days or even weeks beforehand.

By checking your pet’s SRR regularly, you help your vet:

• Detect early signs of congestive heart failure
• Adjust medications before a crisis occurs
• Monitor how well treatment is working
• Keep your pet comfortable and stable for longer

This simple measurement can prevent emergency visits and improve long‑term outcomes.

When to Contact Your Vet

You should reach out to your veterinary team if:

• Your pet’s SRR is consistently above 30 breaths per minute
• You notice a sudden increase compared to their usual baseline
• Your pet is breathing faster, harder, or with more effort
• You’re unsure whether a reading is normal

It’s always better to check in early — small changes can be significant.

A Simple Habit That Makes a Big Difference

Measuring your pet’s sleeping respiratory rate takes less than a minute, but it gives your vet powerful information that can help protect your pet’s health. Whether your pet has a known heart condition or you’re simply being proactive, this daily check is one of the most effective tools you have at home.
