How to Measure. To measure your horse, have him stand square on a level surface. Hold the tape or stick so it is perpendicular to the ground and beside the horse so it is even with the top point of the horseâs withers. If you are using a proper measuring stick, lower the bar so it meets the top of the horseâs withers.
Count the number of beats for 15 seconds, then multiply by four to calculate the heart rate in beats per minute. Remember, any excitement by the horse will increase the pulse rate. If a stethoscope is available, listen to the heart on the left side of the horse's chest, just behind the elbow. Each sound of the heart is considered one beat. The normal heart rate for an adult horse is about 32 to 36 beats per minute. Foal heart rates vary depending on age. Newborn foals have a heart rate of between 80 to 100 beats per minute. Foals which are a few weeks to a few months of age will have heart rates of 60 to 80 beats per minute. Respiration
