How to know if your horse is sick
Check your horse's basic diagnostics.
This means your horse's pulse/heart rate, respiratory rate, and temperature.
Pulse-the normal heart rate for a horse is 25-42 beats per minute.
To check the horse's heart rate, place your palm on the horse's chest just behind the left elbow and feel for the bump-bump-bump of the heart beat. Count how many beats there are in a minute; this is the heart rate.
