If your horse has not recently exercised but is breathing rapidly, it could be a sign of distress or illness. To take a horse respiratory rate, you need attach with a second hand or stopwatch. You may also need a stethoscope if you're following method number 2.
Practice taking respiratory rates when your horse is healthy. Try it when he is at rest and after mild exercise so you can hear the difference.
Method 1: Manual Respiratory Rate Check
1. Watch or feel your horse's ribcage/belly for one minute.
2. Count one inhale and one exhale as one breath.
3. If you are having trouble seeing the ribcage move, you can place your hand in front of your horse's nostril to feel the exhale.
4. Count the number of breaths in a 15-second period and multiply by 4 for breaths-per-minute.
Method 2: Using A Stethescope to Check Respiratory Rate
A stethoscope gives a more detailed report of your horse's respiratory activity. Because it is more sensitive than your ear alone, it is helpful for hearing mucus or obstructions in the windpipe.
1. Place the bell of the stethoscope in the center of your horse’s throat, 6 to 8 inches below his throatlatch.
2. Listen to the air rush by as he inhales and exhales.
3. Count the number of breaths in a 15-second period and multiply by 4 for breaths-per-minute.
Equine Respiratory Rate Tips:
• Rapid breathing at rest requires veterinary attention.
• Watch abdomen for stressful breathing.
• A horse should spend equal time inhaling and exhaling.
• Respiration rate should never exceed the pulse rate.
