Horse Health Problems: Symptoms and When to Worry
The most common Horse health problems are colic, laminitis, and cushing's disease. Horses typically live 25–30 years. This page is organized by symptom, so you can jump straight to digestive, hormonal, joint, and other problems, see what each one looks like in a Horse, and know whether it is a vet visit this week, a vet visit today, or an emergency right now.
Quick answer: when to worry about your Horse
Go to an emergency vet now if you see any of these:
- Stomach and digestive: A horse that is pawing, rolling, looking at its flank, or not passing manure is colic and an emergency. A goat that is bloated on the left side or grinding its teeth in pain needs a vet now.
- Hormonal and metabolic: A horse with sudden laminitis (hot hooves, rocked-back stance) is an emergency and often hormonal in origin.
- Joint, back, and mobility: A horse that will not bear weight on a leg, or a goat down and unable to rise, is an emergency.
- Other: Collapse, difficulty breathing, uncontrolled bleeding, or severe pain is always an emergency.
- Any pet: collapse, seizures lasting more than five minutes, uncontrolled bleeding, or an inability to stand.
Book a vet visit this week if you see any of these:
- Stomach and digestive: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
- Hormonal and metabolic: Weight gain or loss without a diet change, increased thirst, hair loss on the body, a pot-bellied look, or lethargy.
- Joint, back, and mobility: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
- Other: Any change that lasts more than a day or two, or anything that worries you.
Keep watching if: the change is mild, your Horse is still eating, drinking, and moving normally, and it resolves within a day or two. Write down what you saw and when; a dated list is the most useful thing you can bring to a vet.
Stomach and digestive problems in Horses
Colic
Abdominal pain from gas, impaction, or a twisted or displaced gut. Ranges from mild and self-resolving to surgical and fatal within hours.
What it looks like in a Horse:
- Pawing, looking at the flank, rolling
- Sweating and elevated heart rate
- No gut sounds or droppings
- Lying down and getting up repeatedly
When it usually appears: Any age
Outlook: this is one of the conditions that can shorten a Horse's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
When it is an emergency: A horse that is pawing, rolling, looking at its flank, or not passing manure is colic and an emergency. A goat that is bloated on the left side or grinding its teeth in pain needs a vet now.
Hormonal and metabolic problems in Horses
Cushing's disease (PPID)
A pituitary disorder of older horses causing a long curly coat, muscle loss, and susceptibility to laminitis and infection. Managed with daily medication.
What it looks like in a Horse:
- Long coat that does not shed
- Muscle wasting and a pot belly
- Drinking and urinating more
- Recurrent infections and laminitis
When it usually appears: 15 years onward
Outlook: this is one of the conditions that can shorten a Horse's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Weight gain or loss without a diet change, increased thirst, hair loss on the body, a pot-bellied look, or lethargy.
When it is an emergency: A horse with sudden laminitis (hot hooves, rocked-back stance) is an emergency and often hormonal in origin.
Joint, back, and mobility problems in Horses
Arthritis and inability to rise
Degenerative joint disease of old age, progressing until the horse struggles to lie down and get up, which is the point at which euthanasia becomes necessary.
What it looks like in a Horse:
- Stiffness, especially in cold weather
- Reluctance to lie down
- Struggling or failing to rise
- Muscle loss from reduced movement
When it usually appears: 20 years onward
Outlook: this is one of the conditions that can shorten a Horse's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
When it is an emergency: A horse that will not bear weight on a leg, or a goat down and unable to rise, is an emergency.
Other health problems in Horses
Laminitis
Inflammation and failure of the tissues attaching the hoof to the bone, often triggered by metabolic disease or rich grass. Chronic cases lead to rotation of the pedal bone and unmanageable pain.
What it looks like in a Horse:
- Rocked-back stance
- Reluctance to move or turn
- Heat in the hooves and a bounding digital pulse
- Lying down more
When it usually appears: Any age, especially ponies and older horses

Warning signs to watch for in a Horse
These are the early signals owners most often miss, or dismiss as age:
- Repeated colic episodes
- Difficulty rising or a horse found down
- A rocked-back laminitic stance
- Weight loss despite good feed and teeth
- A horse standing away from the herd with a dull eye
Horse lifespan: what is normal
Twenty-five to thirty years is typical, with ponies often living into their mid-thirties. Colic and laminitis take horses at any age. A horse in its late twenties is elderly and usually managed for arthritis, teeth, and metabolic disease.
Genetic factors
Ponies and native breeds are prone to laminitis and metabolic syndrome. Grey horses develop melanomas. Thoroughbreds and Warmbloods face more orthopaedic disease. Cushing's (PPID) affects a large proportion of horses over twenty regardless of breed.
What Horses usually die from
Knowing what typically ends a Horse's life is not morbid. It tells you which of the symptoms above deserve the fastest response.
- Colic: The leading cause of death in horses across all ages.
- Laminitis: Chronic or acute; euthanasia for unmanageable pain.
- Old age and inability to rise: Arthritis, weakness, and the decision that follows a horse going down.
- Cushing's complications: Laminitis and infection in older horses with PPID.
When it may be time: from managing symptoms to saying goodbye
Some of the conditions above (colic, laminitis, and cushing's disease) are managed for years. Each one, though, has a point where treatment prolongs the decline rather than the life. If you are reading this page because your Horse is older and the bad days are starting to outnumber the good, that is worth saying plainly: you may not be looking for a diagnosis anymore. You may be looking for permission.
Signs the balance has shifted in a Horse:
- Struggling to rise, or being found down and unable to get up
- Repeated colic episodes, or a colic that does not respond to treatment
- A laminitic stance: rocked back, reluctant to move or turn
- Weight loss despite good feed and dental care
The when to say goodbye to your Horse guide walks through the quality-of-life scale vets use, what euthanasia actually involves, and how to prepare. If you are weighing costs and options, the pet end-of-life services guides by city cover in-home euthanasia and cremation prices, and the coping with losing a Horse guide is there for afterward.
Preventive care for Horses
- Regular dental care; poor teeth in old horses lead to weight loss and colic
- Manage grass access for ponies and metabolic horses
- Test older horses for Cushing's and treat it
- Consistent feeding and turnout routines reduce colic risk
- Have an end-of-life plan agreed with your vet before you need it, including removal

If this has stopped being about symptoms
Many people land here when their Horse is old or ill and they are trying to work out whether what they are seeing is the end. If that is you, the health details above matter less than the question underneath them.
