Senior Horse Vital Signs Chart (TPR & More)
Normal horse vital signs reference: temperature 99 to 101F, pulse 28 to 44 bpm, respiration 8 to 16, plus gut sounds, capillary refill, and gum color, with warning signs.
Quick answer: A healthy adult horse at rest has a temperature of about 99 to 101 degrees Fahrenheit (37.2 to 38.3 C), a heart rate of 28 to 44 beats per minute, and a respiratory rate of 8 to 16 breaths per minute. Gut sounds should be present in all four flank quadrants, capillary refill time should be 1 to 2 seconds, and gums should be moist and pale pink. Knowing your individual horse's normal resting values makes it far easier to spot trouble early.
Normal Horse Vital Signs Chart
The core vital signs are often abbreviated TPR: temperature, pulse, and respiration. Always take them when the horse is calm and at rest, since heat, exercise, and stress raise the numbers. The chart below lists normal adult ranges and what abnormal readings may suggest.
| Vital Sign | Normal Range (Adult, at Rest) | What Abnormal May Mean |
|---|---|---|
| Temperature | 99 to 101 F (37.2 to 38.3 C) | Above ~101.5 F suggests fever or infection; very low can signal shock or cold stress. |
| Pulse / Heart Rate | 28 to 44 beats per minute | Elevated rate can mean pain, fever, dehydration, or distress. |
| Respiration | 8 to 16 breaths per minute | Rapid or labored breathing at rest can mean respiratory disease, pain, or heat stress. |
| Gut Sounds | Present in all four flank quadrants | Quiet or absent sounds can accompany colic; excessive sounds can also signal a problem. |
| Capillary Refill Time | 1 to 2 seconds | Longer than 2 to 3 seconds suggests dehydration, poor circulation, or shock. |
| Mucous Membranes (Gums) | Moist, pale pink | Pale, brick red, bluish, or yellow gums indicate serious problems; dry or tacky means dehydration. |
| Skin Pinch (Hydration) | Snaps back in under ~2 seconds | A tent that stays raised suggests dehydration. |
| Digital Pulse (Feet) | Faint or hard to feel | A strong, bounding digital pulse can signal laminitis or foot inflammation. |
These are general adult ranges. Foals run higher heart and respiratory rates, and individual horses vary, which is exactly why knowing your own horse's baseline is so valuable. Take and record your healthy horse's resting TPR a few times so you have a personal reference to compare against on a worrying day.
Why Vital Signs Matter for Senior Horses
Older horses can decline quickly, and they are more prone to the conditions that vital signs help detect: infections, dental-related problems, colic, heart and respiratory changes, and laminitis tied to PPID or metabolic disease. A senior horse may also mask illness until it is well established, so an owner who can quickly take a temperature, count a pulse and respiration, listen for gut sounds, and check gum color and digital pulses has a real advantage. These simple, no-cost checks turn a vague sense that something is off into concrete numbers you can give your vet over the phone.
The digital pulse deserves special mention for seniors. A strong, bounding pulse felt at the back of the pastern, especially with heat in the hoof and a reluctance to move, is a classic warning of laminitis, a condition that older PPID and metabolic horses are at heightened risk of. Learning to feel a normal, faint digital pulse means you can recognize an abnormal one early, when prompt veterinary care matters most.
Putting It to Work
Keep a thermometer, a stethoscope, and a written record of your horse's normal values in the barn. Practice taking vitals on a healthy day so the routine is familiar in an emergency. If you find a fever, a high resting heart rate, labored breathing, a quiet gut, slow capillary refill, abnormal gum color, or a bounding digital pulse, write down the numbers and call your veterinarian. These vital signs guide decisions but do not diagnose, and an off reading in a senior is a reason to seek professional help promptly.

Frequently Asked Questions
What is a normal temperature for a horse?
A healthy adult horse's normal rectal temperature is about 99 to 101 degrees Fahrenheit (37.2 to 38.3 degrees Celsius). A reading above roughly 101.5 degrees suggests a fever and warrants attention, while a very low temperature can also signal a problem. Temperature rises with hot weather, exercise, and stress, so take it when the horse is at rest for an accurate baseline. Knowing your individual horse's normal resting temperature makes it much easier to recognize when something is wrong.
What is a normal heart rate for an adult horse?
A resting adult horse's heart rate is normally about 28 to 44 beats per minute, with many healthy horses sitting in the low to mid 30s. Foals and young horses run faster. You can count the pulse with a stethoscope behind the left elbow or by feeling the artery under the jaw, counting beats for 15 seconds and multiplying by four. A persistently elevated resting heart rate can indicate pain, fever, dehydration, or distress and should prompt a call to your vet.
What is a normal respiratory rate for a horse?
A horse at rest normally breathes about 8 to 16 breaths per minute. Watch the flank or nostrils rise and fall, counting one full in-and-out as a single breath over a minute. Heat, humidity, exercise, and stress raise the rate temporarily. Rapid, labored, or noisy breathing at rest, flared nostrils, or an exaggerated heave at the flank are warning signs of respiratory trouble or pain and deserve veterinary attention, especially in an older horse.
How do I check a horse's gut sounds?
Press an ear or a stethoscope against the flank on both sides, high and low, and listen for gurgles, rumbles, and the occasional roar of a normal, active gut. You should hear sounds on all four quadrants within a minute or so. A quiet or silent gut is concerning, because reduced or absent gut sounds can accompany colic. Very loud, frequent sounds can also signal a problem. Gut sounds are a key part of a colic check, so learning your horse's normal is valuable.
What is capillary refill time and what is normal?
Capillary refill time (CRT) checks circulation. Press a thumb against the horse's gum above the teeth until the spot blanches white, then release and count how long the pink color takes to return. Normal is about 1 to 2 seconds. A refill time longer than 2 to 3 seconds suggests poor circulation, dehydration, or shock and is a warning sign that needs veterinary attention. CRT is checked alongside gum color and moisture as part of assessing a sick or colicky horse.
What color should a horse's gums be?
Healthy mucous membranes, seen on the gums above the teeth, are normally a moist, pale pink, similar to healthy human gums. Pale or white gums can indicate blood loss or shock, while brick red, bluish, or yellow gums suggest serious problems such as toxicity, poor oxygenation, or liver disease. The gums should also feel moist, not tacky or dry, which would suggest dehydration. Checking gum color, moisture, and capillary refill together gives a quick read on a horse's circulation and hydration.
When should I call the vet about a senior horse's vital signs?
Call promptly for a temperature above about 101.5 degrees Fahrenheit, a resting heart rate persistently above 44 to 48 beats per minute, labored or very rapid breathing at rest, a quiet or absent gut, capillary refill longer than 2 to 3 seconds, or abnormal gum color. Any one of these, especially combined with signs of pain, colic, or distress, is a reason to contact your vet. Senior horses can decline quickly, so when in doubt, take the vitals, write them down, and call.
