How to Check Your Horse’s Health at Home

By Dr Duncan Houston

You do not need a full veterinary setup to notice when something is wrong with your horse.

Some of the most useful health clues are right in front of you: body condition, appetite, manure, coat quality, gum colour, temperature, heart rate, breathing rate, gut sounds, and behaviour. The real skill is not just collecting numbers. It is knowing what is normal for your horse, what has changed, and when that change becomes urgent.

A horse that looks “a bit quiet” can be early colic. A horse that slowly gains weight can be drifting toward laminitis risk. A horse with a dull coat may have parasites, dental disease, poor nutrition, or systemic illness. Home monitoring helps you notice these patterns earlier and gives your vet better information when you call.

Quick Answer

The most useful at-home horse health checks are body condition score, appetite, water intake, manure, temperature, pulse, respiration, gum colour, capillary refill time, gut sounds, coat quality, and behaviour. A healthy adult horse at rest commonly has a rectal temperature around 99 to 101°F, a heart rate around 28 to 48 beats per minute, and a resting respiratory rate around 8 to 14 breaths per minute, although individual baselines and conditions such as exercise, heat, stress, and pain matter. If your horse is not eating, has colic signs, a fever, abnormal gum colour, breathing difficulty, severe lameness, or rapidly changing behaviour, call a veterinarian promptly. (NJAES)

Why Home Monitoring Matters

Home monitoring is not about replacing your vet. It is about spotting changes early enough that veterinary care can happen before the problem becomes harder, riskier, or more expensive to treat.

In practice, the most useful owner observations are usually simple:

• Is the horse eating normally?

• Is the horse drinking normally?

• Is manure normal for that horse?

• Is the horse bright, alert, and responsive?

• Is the horse moving normally?

• Are the vital signs close to that horse’s usual baseline?

• Has the horse gained or lost condition?

• Has the coat changed?

• Is anything different from yesterday?

That last question matters most. Many owners look for dramatic signs, but horses often start with subtle changes. Less interest in feed. Standing slightly away from the herd. Fewer manure piles. A raised heart rate. A duller expression. A coat that is not shedding properly.

The earlier you notice these changes, the better your horse’s chances.

What Should You Check First?

If you are worried about your horse, start with the basics before getting lost in details.

Check:

1. Attitude

2. Appetite

3. Water intake

4. Manure

5. Movement

6. Temperature

7. Heart rate

8. Respiration rate

9. Gum colour

10. Gut sounds

If these are normal and your horse is bright, eating, drinking, passing manure, and moving comfortably, the situation is usually less urgent. If several of these are abnormal at the same time, the concern rises quickly.

A horse that is quiet but eating normally is one thing. A horse that is quiet, not eating, passing little manure, with a raised heart rate is a very different beast.

Body Condition Score: One of the Best Long-Term Health Checks

Body condition score, or BCS, is a practical way to assess whether your horse is too thin, too fat, or sitting in a healthy range.

The commonly used Henneke scale scores horses from 1 to 9, with 1 being severely underweight and 9 being severely overweight. You assess fat cover over key areas including the ribs, neck, withers, loin, tailhead, shoulder, and elbow area. Rutgers notes that body condition scoring should involve both visual inspection and hands-on assessment, not just looking from across the paddock. (Equine Science Center)

A useful guide:

Score	Meaning	What it suggests
1 to 3	Too thin	Possible poor nutrition, dental disease, parasites, chronic pain, illness, or neglect
4	Lean	May be acceptable for some fit performance horses
5 to 6	Healthy for many horses	Often a good target range, depending on age, breed, workload, and reproductive status
7	Overconditioned	Increased concern for joint strain, metabolic risk, and management changes
8 to 9	Obese	Higher concern for insulin dysregulation, equine metabolic syndrome, and laminitis risk

Most horses are often best around a BCS of 5 to 6, although the ideal score can vary by discipline, age, breeding status, and health. Alabama Cooperative Extension notes that high BCS increases the risk of equine metabolic syndrome, insulin dysregulation, altered glucose dynamics, and laminitis. (Alabama Cooperative Extension System)

The mistake I see most often is owners relying on the ribs alone. Ribs matter, but you also need to feel the neck crest, tailhead, shoulders, withers, and topline. A horse can have visible ribs and still have abnormal fat deposits along the crest, especially in metabolic cases. Sneaky, annoying, and very horse-like.

How Often Should You Body Condition Score Your Horse?

For a healthy adult horse, check body condition at least monthly.

Check more often if your horse is:

• Senior

• Pregnant or lactating

• Growing

• In heavy work

• Recovering from illness

• Prone to laminitis

• An easy keeper

• Losing weight

• Changing feed or pasture access

• Growing a thick winter coat

Michigan State University Extension recommends body condition scoring at least monthly in healthy horses and more often in horses that struggle to maintain a healthy body weight. It also notes that winter coats can make visual assessment harder, which is why hands-on checks matter. (MSU College of Ag and Nat Resources)

A photo once a month from the side, front, and rear can be surprisingly useful. Weight gain and loss are easier to see when you compare photos instead of relying on memory.

Temperature, Pulse, and Respiration

Temperature, pulse, and respiration are often called TPR. These are simple checks, but they can tell you a lot about pain, infection, stress, dehydration, heat stress, respiratory disease, and colic risk.

Approximate resting adult horse values:

Measurement	Typical adult range at rest	Why it matters
Temperature	About 99 to 101°F	Fever may suggest infection, inflammation, heat stress, or systemic illness
Heart rate	About 28 to 48 beats per minute	Elevation may suggest pain, stress, dehydration, fever, shock, or colic
Respiration	About 8 to 14 breaths per minute	Elevation may suggest pain, fever, heat stress, respiratory disease, or distress

Rutgers gives normal adult horse heart rate as 28 to 48 beats per minute and resting respiration as approximately 8 to 14 breaths per minute. It also advises calling a veterinarian if a resting horse’s temperature is higher or lower than 99 to 101°F. (NJAES)

Do not panic over one slightly abnormal number in isolation. A hot day, recent exercise, anxiety, pain, or excitement can alter the values. What matters is the full picture: the horse’s behaviour, appetite, manure, gum colour, hydration, and whether the numbers settle with rest.

How to Take Your Horse’s TPR

For temperature, use a digital rectal thermometer. Label it clearly, lubricate it, stand safely to the side, and hold it in place until it reads. Do not let it disappear into the horse. That is not a fun phone call for anyone.

For pulse, you can feel under the jaw at the facial artery or use a stethoscope behind the left elbow. Count for 15 seconds and multiply by 4.

For respiration, watch the flank or ribcage rise and fall while the horse is relaxed. One inhale plus one exhale equals one breath. Count for 15 seconds and multiply by 4. Avoid putting your hand near the nostril if it makes the horse sniff, fidget, or change its breathing pattern.

Rutgers recommends assessing pulse under the jaw or with a stethoscope behind the left elbow, and counting breaths by watching the ribs or flank while the horse is relaxed. (NJAES)

The best time to learn TPR is when your horse is healthy. That way, when something is wrong, you are not learning anatomy while your horse is trying to turn your stable into interpretive dance.

Gum Colour and Capillary Refill Time

Your horse’s gums are a useful circulation and hydration checkpoint.

Normal gums should usually be:

• Pink

• Moist

• Slippery rather than tacky

• Not dark red, purple, blue, grey, yellow, or very pale

Capillary refill time, or CRT, is checked by pressing a finger on the gum, releasing, and seeing how long it takes the pink colour to return. Around 2 seconds or less is commonly considered normal.

Abnormal gums can be a red flag. Pale gums may suggest shock, blood loss, or poor circulation. Brick-red or purple gums can suggest serious systemic disease or compromised circulation. Yellow gums can suggest liver disease or red blood cell breakdown. Tacky gums can suggest dehydration.

UC Davis includes changes in gum colour and increased heart rate among concerning colic-related vital sign changes. (Horse Report)

If your horse has abnormal gum colour plus dullness, colic signs, sweating, weakness, laboured breathing, or an elevated heart rate, do not sit on it. Call your vet.

Gut Sounds: Useful, But Not Perfect

Gut sounds are the gurgles, bubbles, fluid sounds, and gas movements you hear when listening to the abdomen.

You can listen with a stethoscope in four areas:

• Left upper abdomen

• Left lower abdomen

• Right upper abdomen

• Right lower abdomen

Normal gut sounds vary. Some horses are naturally noisy. Some are quieter. The key is learning what is normal for your horse.

Concerning findings include:

• No gut sounds or very reduced gut sounds

• A sudden major change from normal

• Gut sounds plus colic signs

• Very loud, fluidy sounds with diarrhoea

• Quiet abdomen with no manure or reduced appetite

UC Davis lists reduced or absent gut sounds, lack of manure, loose or dry manure, eating less or not eating, and dullness as warning signs when assessing possible colic. (Horse Report)

Gut sounds do not give a diagnosis by themselves. A noisy gut does not guarantee safety. A quiet gut does not tell you exactly what is wrong. But gut sounds are useful when combined with appetite, manure, heart rate, gum colour, and behaviour.

Manure: The Paddock Report Card

Manure is one of the easiest things to monitor and one of the most commonly ignored.

Normal manure should usually be formed, moist, and fairly consistent for that horse. Some variation happens with diet, pasture, travel, stress, weather, and workload. What matters is a sudden or persistent change.

Watch for:

• Diarrhoea

• Very watery manure

• Hard, dry manure

• Fewer manure piles than normal

• No manure

• Mucus

• Blood

• Sand or soil

• Undigested long fibres

• Whole grain

• Foul smell

• Worms or unusual material

Dry, hard manure can suggest dehydration, reduced intake, impaction risk, or low gut movement. Loose manure can come from diet change, stress, parasites, infection, inflammatory disease, antibiotics, or sand irritation.

Large stems, unchewed feed, or whole grain in manure can point toward dental disease or chewing problems. University of Florida notes that dental disease can cause difficulty chewing, dropping partially chewed food, quidding, excess salivation, weight loss, and long stems or large feed particles in manure. (Ask IFAS - Powered by EDIS)

If manure changes and your horse is still bright, eating, drinking, and comfortable, monitor closely and review recent diet or management changes. If manure changes occur with colic signs, fever, depression, dehydration, or reduced appetite, call your vet.

Coat Quality: Helpful, But Not a Diagnosis

A shiny coat is not proof of perfect health, and a dull coat is not one diagnosis.

Coat quality can be affected by:

• Nutrition

• Parasites

• Dental disease

• Skin disease

• Lice or mites

• Rain scald

• Ringworm

• PPID in older horses

• Chronic illness

• Poor grooming

• Weather

• Rugging

• Seasonal shedding

UC Davis lists diarrhoea, weight loss, fever, and poor coat condition as clinical signs associated with large and small strongyles, while ascarid infection can be associated with poor growth, rough hair coat, coughing, diarrhoea, and colic in young horses. (Center for Equine Health)

In practice, I take coat changes seriously when they come with other signs: weight loss, dullness, diarrhoea, poor appetite, poor performance, delayed shedding, muscle loss, or recurrent infections.

A dull coat alone might be grooming and weather. A dull coat plus weight loss and loose manure is a different conversation.

Appetite and Behaviour: Often the Earliest Warning Signs

Owners often underestimate how important appetite and behaviour are.

Call your vet sooner rather than later if your horse:

• Refuses grain or usual feed

• Stops eating hay

• Stops grazing

• Drinks much less than usual

• Is dull or withdrawn

• Separates from the herd

• Lies down more than usual

• Paws, looks at the flank, kicks at the belly, or rolls

• Sweats without obvious reason

• Seems weak, wobbly, or depressed

• Suddenly becomes aggressive or reactive

• Shows a sudden change in normal personality

UC Davis advises owners to know how to assess vital signs and monitor temperature, heart rate, respiratory rate, gut sounds, capillary refill time, and mucous membranes so they can recognise changes that indicate a problem. (Horse Report)

One of the best things you can tell a vet is: “This is not normal for him.”

That sentence is clinically useful.

Severity Framework: How Worried Should You Be?

Low Risk

Low-risk findings include mild changes in coat, small weight changes over weeks, slightly softer manure after a diet change, or a one-off mild change in behaviour where the horse is still bright, eating, drinking, passing manure, and moving normally.

Action: Monitor closely, record the change, check TPR if safe, and review feed, water, weather, workload, and management.

Moderate Risk

Moderate concern includes mild weight loss, gradual weight gain, repeated soft manure, mild reduction in appetite, a mildly elevated temperature, mild stiffness, dull coat with no obvious cause, or subtle behavioural change lasting more than 24 hours.

Action: Arrange a vet check or discuss the signs with your vet. Do not wait months for weight loss, poor coat, or ongoing manure changes to “sort itself out.”

High Risk

High concern includes not eating normally, reduced manure, diarrhoea, fever, raised heart rate, abnormal gum colour, mild colic signs, dehydration, sudden lameness, rapid weight loss, or a horse that is clearly dull or isolated.

Action: Call your veterinarian promptly. Same-day advice is often appropriate.

Critical Risk

Critical concern includes severe colic signs, repeated rolling, collapse, severe weakness, difficulty breathing, very abnormal gums, heavy bleeding, severe lameness, eye injury, choke, neurological signs, suspected poisoning, severe diarrhoea, or any horse that is not eating and looks unwell.

Action: Treat this as an emergency.

What Else Could Be Going On?

Home checks help you notice a problem. They do not always tell you the cause.

If your horse is losing weight

Important possibilities include:

• Not enough calories

• Poor-quality forage

• Dental disease

• Parasites

• Gastric ulcers

• Chronic pain

• Poor herd access to feed

• PPID

• Liver disease

• Kidney disease

• Cancer

• Chronic infection

• Inflammatory bowel disease

If your horse is gaining weight

Important possibilities include:

• Too much grass

• Too much hay

• Too much hard feed

• Lack of exercise

• Easy-keeper metabolism

• Insulin dysregulation

• Equine metabolic syndrome

• Reduced workload after injury

If your horse has abnormal manure

Important possibilities include:

• Diet change

• Stress

• Dehydration

• Dental disease

• Parasites

• Sand accumulation

• Colic

• Infectious diarrhoea

• Antibiotic-associated diarrhoea

• Inflammatory bowel disease

If your horse has a dull coat

Important possibilities include:

• Seasonal coat changes

• Nutrition imbalance

• Parasites

• Dental disease

• Skin infection

• External parasites

• PPID

• Chronic illness

This is why trends matter. A single sign gives you a clue. A pattern gives your vet a direction.

When Is This an Emergency?

Call a veterinarian urgently if your horse has:

• Colic signs such as pawing, rolling, flank watching, sweating, or repeated lying down

• Not eating or drinking

• No manure or markedly reduced manure

• Severe diarrhoea

• Fever

• Laboured breathing

• Heart rate that remains high at rest

• Pale, purple, blue, yellow, or brick-red gums

• Tacky gums with dullness or dehydration signs

• Severe lameness

• Suspected laminitis

• Eye injury or a painful closed eye

• Choke

• Collapse or severe weakness

• Neurological signs

• Suspected poisoning

• Deep wounds or heavy bleeding

• Rapid deterioration over hours

• Multiple horses affected at the same time

UC Davis recommends calling a veterinarian when colic is recognised and advises owners not to give medications unless directed by the veterinarian. It also lists pawing, flank watching, rolling, sweating, lack of manure, loose or dry manure, increased heart rate, reduced or absent gut sounds, gum colour changes, eating less, and dullness as signs that should trigger concern. (Horse Report)

The big rule is simple: if your horse is not eating and does not look right, do not wait and hope.

What Should You Do Next?

If your horse seems normal

Create a baseline.

Record:

• Normal temperature

• Normal heart rate

• Normal respiratory rate

• Normal gum colour

• Normal manure pattern

• Normal appetite

• Normal water intake

• Monthly body condition score

• Photos from the side, front, and rear

This makes future changes much easier to interpret.

If something is mildly abnormal

Check the full picture.

Ask:

• Is the horse eating?

• Is the horse drinking?

• Is manure normal?

• Is the horse bright?

• Is the horse moving normally?

• Are TPR values close to normal?

• Has anything changed in feed, pasture, weather, exercise, travel, medication, or herd dynamics?

Monitor for 12 to 24 hours if the horse is bright and comfortable, but escalate sooner if signs worsen.

If multiple things are abnormal

Call your vet.

A horse with reduced appetite plus fewer manure piles plus a raised heart rate is not a “wait a week” case. A horse with dullness plus fever plus diarrhoea needs veterinary input. A horse with abnormal gums plus weakness is urgent.

If you call your vet

Have useful information ready:

• Temperature

• Heart rate

• Respiratory rate

• Gum colour

• Capillary refill time

• Appetite

• Water intake

• Manure output

• Recent feed or pasture changes

• Recent travel or competition

• Deworming history

• Vaccination history

• Current medications

• Any previous colic, laminitis, ulcers, dental disease, or metabolic problems

A good owner history can save time and help your vet make better decisions.

Common Mistakes Horse Owners Make

Only checking when the horse is already sick

Learn your horse’s normal values when they are well. That is when the numbers become useful.

Assuming a shiny coat means everything is fine

A shiny horse can still have ulcers, metabolic disease, dental pain, lameness, or early colic.

Ignoring slow weight gain

Gradual obesity is easy to miss. It still increases risk, especially in easy keepers and laminitis-prone horses.

Waiting too long with weight loss

Weight loss is not fixed by simply adding more feed if the real cause is dental disease, parasites, chronic pain, or illness.

Giving medication before calling the vet

Pain relief can mask important signs, especially in colic. UC Davis specifically advises not giving medication during colic unless directed by a veterinarian. (Horse Report)

Not tracking manure

Manure is boring until it is not. Fewer piles, dry manure, diarrhoea, or no manure can matter a lot.

Overreacting to one number

A single mildly abnormal vital sign should be interpreted with the horse’s behaviour, recent exercise, weather, stress, and overall clinical picture.

How to Prevent Health Problems Through Better Monitoring

You cannot prevent every horse health problem, but you can catch many earlier.

A practical prevention routine includes:

• Daily appetite and manure checks

• Daily behaviour and movement checks

• Clean water monitoring

• Monthly body condition scoring

• Regular weight tape measurements

• Regular hoof care

• Routine dental checks

• Faecal egg count-based parasite control

• Vaccination planning with your vet

• Slow feed and pasture changes

• Safe exercise and turnout

• Shelter from heat, cold, rain, and insects

• Monitoring older horses for PPID, dental disease, arthritis, and weight change

• Keeping emergency contacts visible in the barn

AAEP notes that colic is a major cause of horse death and that management can play an important role in reducing risk, even though not every case is preventable. (AAEP)

Good monitoring does not make you paranoid. It makes you prepared.

Simple Weekly Horse Health Checklist

Use this once a week for a healthy horse, and more often for horses with known issues.

Check	What you want
Appetite	Eating normally and finishing usual feed
Water	Drinking normally for weather and workload
Manure	Normal amount, shape, moisture, and frequency
Behaviour	Bright, responsive, normal personality
Movement	Walking comfortably, no new stiffness or lameness
Coat	Normal shine, shedding, and skin condition
Body condition	No rapid gain or loss
Gums	Pink and moist
TPR	Within your horse’s normal resting range
Gut sounds	Present and normal for that horse

The point is not to obsess over every tiny variation. The point is to notice patterns before they become problems.

FAQs

How often should I check my horse’s vital signs?

Check them when your horse is healthy so you know their normal baseline. For routine monitoring, many owners check periodically, such as weekly or monthly. Check immediately if your horse seems dull, off feed, colicky, feverish, lame, or not right.

What is the most important sign that my horse is sick?

Appetite is one of the biggest warning signs. A horse that stops eating, eats less than normal, or is dull around feed should be taken seriously, especially if there are manure changes, colic signs, fever, or a raised heart rate.

Is a body condition score of 7 bad?

A BCS of 7 means the horse is carrying more fat than ideal. It is not automatically an emergency, but it should prompt a weight management plan. Higher body condition increases concern for metabolic disease, insulin dysregulation, and laminitis risk.

Should I listen to my horse’s gut sounds?

Yes, if you can do it safely. Gut sounds can be useful, especially if you know what is normal for your horse. Reduced or absent gut sounds, especially with colic signs, reduced manure, or not eating, should be treated seriously.

When should I call a vet instead of monitoring?

Call a vet if your horse is not eating, has colic signs, fever, abnormal gums, laboured breathing, severe lameness, diarrhoea, no manure, neurological signs, sudden collapse, or worsening signs over a few hours.

Final Thoughts

The best horse owners are not the ones with the fanciest equipment. They are the ones who know what normal looks like.

Normal appetite. Normal manure. Normal attitude. Normal movement. Normal body condition. Normal temperature, pulse, and respiration. Once you know those baselines, small changes become easier to spot and emergencies become easier to explain clearly to your vet.

Home monitoring is not about diagnosing everything yourself. It is about noticing early, acting sensibly, and giving your horse the best chance of a good outcome.

Your horse cannot tell you, “I feel strange today.” But they will show you. Your job is to pay attention before the whisper becomes a shout.
