PetSci Seizure Tracker
Track and log your pet's seizures with date, duration, type, and triggers. Share detailed reports with your vet to improve epilepsy management.
Open TrackerChoose dog or cat first, then enter the details that match your pet's species, weight, routine, and current situation.
Monitoring your pet's resting respiratory rate (RRR) is one of the most powerful and underutilized home monitoring tools available to pet owners. The resting respiratory rate is the number of breaths per minute counted while the animal is calm and sleeping or resting. Elevations in RRR can be the earliest detectable sign of congestive heart failure (CHF), respiratory disease, pain, pneumonia, or pulmonary hypertension - often detectable before any outward clinical symptoms appear. The Pet Breath Counter guides you through correctly counting and interpreting your pet's resting respiratory rate.
Normal Resting Respiratory Rate Ranges
Use the table below to compare Normal Resting Respiratory Rate Ranges.
| Species/Status | Normal Resting Rate (breaths/min) | Action Threshold | Emergency Threshold |
|---|---|---|---|
| Adult dog | 10-30 | Above 30 on two consecutive counts 1 hour apart | Above 40 |
| Adult cat | 20-30 | Above 30 on two consecutive counts | Above 40 |
| Puppy (under 6 months) | 15-40 | Context-dependent; elevated range normal | Above 50 |
| Kitten (under 6 months) | 20-40 | Context-dependent | Above 50 |
| Dog in CHF management | Target below 30 at rest | Above 30 = call vet same day in known CHF dog | Above 40 = emergency in CHF dog |
How to Count the Resting Respiratory Rate
- Wait until your pet is fully relaxed and sleeping or resting - do not measure during play, eating, or when they are alert
- Watch the chest or belly rise and fall - one complete rise and fall = one breath
- Count the number of breaths in 30 seconds and multiply by 2 for breaths per minute (or count a full 60 seconds for more accuracy)
- Take the measurement 2-3 times at different rest periods and average the results
- Record the result with date and time - trends over time are as important as single readings
- Measure at the same time of day for comparability (many owners choose evening before the pet's last meal)
Conditions That Elevate Resting Respiratory Rate
Use the table below to compare Conditions That Elevate Resting Respiratory Rate.
| Condition | Typical RRR | Additional Signs | Urgency |
|---|---|---|---|
| Congestive heart failure | 30-60+ | Cough (dogs), open-mouth breathing (cats), lethargy, reduced appetite | Urgent - call vet same day if above 30 in known CHF patient |
| Pleural effusion (fluid around lungs) | 30-60+ | Labored breathing, reluctance to lie down, hunched posture | Emergency |
| Pneumonia | 30-50+ | Cough, fever, reduced appetite, nasal discharge | Urgent veterinary care |
| Asthma (cats) | 30-60 | Wheeze, crouch posture, extended neck, abdominal breathing effort | Acute attack: emergency; controlled: urgent vet visit |
| Pain | 25-40 | Context-dependent; restlessness, behavioral change | Veterinary assessment for pain source |
| Anxiety/stress | 25-35 | Context-dependent; settles with trigger removal | Not dangerous if brief and associated with known stressor |
Pet Breath Counter Apps
Several free apps (CardioScreen, Cardalis RR, OvuseMedical) allow owners of cardiac patients to log RRR over time with automated graphing and threshold alerts. These are particularly valuable for dogs with known mitral valve disease or DCM where CHF is a progressive risk. Many veterinary cardiologists now recommend using these apps as part of home monitoring protocols for at-risk pets.
Frequently Asked Questions
My dog's rate was 32 once but is normally 18-22. Should I worry?
A single elevated reading in an otherwise well dog who was slightly warm, had just woken up, or was in an unusual environment is less concerning than a sustained elevation. Recount 1-2 hours later in a fully relaxed state. If still above 30 on three consecutive separate measurements, contact your vet.
Is panting the same as a high respiratory rate?
Panting is a different mechanism - it is thermoregulatory (temperature regulation) and occurs with the mouth open. It should not be counted as the resting respiratory rate. Count only closed-mouth chest rise and fall. If your pet is panting at rest when they should not be (not hot, not just exercised), this is a symptom warranting veterinary attention independent of the respiratory rate count.
Note: Resting breathing rate is most useful when measured during sleep or calm rest and compared with your pet's usual pattern.
