Cushing’s Disease in Horses: Early Signs You Should NEVER Ignore

Cushing’s syndrome in horses, now commonly referred to as PPID (Pituitary Pars Intermedia Dysfunction), is one of the most frequently diagnosed hormonal disorders in horses. It primarily affects older horses, most often over 15 years of age. Although it was once considered a natural part of aging, it is now known to be a serious endocrine disorder that requires treatment and ongoing management.

In reality, PPID in horses is a complex condition caused by dysfunction of the pituitary gland. This leads to the overproduction of hormones, especially ACTH, which in turn increases the release of cortisol—the stress hormone. As a result, numerous metabolic and immune disturbances can occur, often presenting in various ways. Common symptoms of Cushing’s disease in horses include excessive hair growth (hirsutism), problems with shedding, excessive sweating, muscle loss, lethargy, increased susceptibility to infections, and frequent cases of laminitis.

For many years, horse owners often did not realize that a horse showing these symptoms was not simply “old,” but was actually suffering from Cushing’s syndrome. Today, thanks to growing awareness and advances in veterinary medicine, the condition is being diagnosed more often and at earlier stages. Early diagnosis allows for effective treatment of Cushing’s in horses, better control of symptoms, and an improved quality of life.

Owners of older horses should pay close attention to early signs—even seemingly minor changes in coat condition, overall fitness, or behavior may indicate the development of PPID. Regular veterinary check-ups and consultations can help detect the disease before serious complications arise.

This article will help you understand what Cushing’s syndrome in horses is, how to recognize early symptoms, how diagnosis is carried out, and what daily care and treatment involve. Although PPID is a chronic condition, with the right approach, proper diet, and attentive care, an older horse with this disease can still enjoy a long and happy life.

What is Cushing’s Disease in Horses? (PPID Explained)

Cushing’s syndrome in horses, now referred to as PPID (Pituitary Pars Intermedia Dysfunction), is one of the most common hormonal disorders in horses. It results from abnormal function of the pituitary gland. The pituitary, a small gland located at the base of the brain, plays a key role in regulating metabolic, immune, and stress-related processes. It is responsible for releasing hormones that maintain balance throughout the horse’s body.

In horses with PPID, the pituitary gland does not function properly—there is enlargement and overactivity of the cells in the intermediate part of the gland, which produce excessive amounts of ACTH (adrenocorticotropic hormone). The excess ACTH continuously stimulates the adrenal glands to release cortisol, known as the stress hormone. Elevated cortisol levels disrupt metabolic balance and lead to serious health consequences, including weakened immunity, muscle loss, slowed metabolism, skin problems, and an increased risk of laminitis.

PPID in horses develops slowly and often goes unnoticed for years. The first signs of Cushing’s disease in horses are often subtle—a horse may become lethargic, lose muscle mass, have difficulty shedding, or sweat excessively. Over time, the condition begins to affect multiple body systems, leading to chronic weakness, immune issues, and mood changes. Despite this, an older horse with PPID can live for many years in good condition if it receives proper care and treatment.

Modern veterinary medicine allows for effective treatment of Cushing’s disease in horses. The use of medications such as pergolide (Prascend), along with a properly balanced diet and stress reduction, helps control the condition and improve the horse’s quality of life. Many owners notice that after starting treatment, a horse with PPID regains energy, enthusiasm, and willingness to work.

It is important that owners of older horses do not treat PPID as a natural consequence of aging. Cushing’s syndrome in horses is not simply old age, but a specific hormonal disorder that can be effectively managed. Regular diagnostics, observation, and proper treatment provide the opportunity for a long and healthy life.

Understanding what PPID in horses truly is allows owners to better recognize their horses’ needs and respond in time. With the right knowledge and care, more and more horses with this condition are able to enjoy calm, active lives—despite the diagnosis.

Symptoms of Cushing’s Syndrome in Horses

Cushing’s syndrome in horses is a hormonal disorder that develops slowly and insidiously. For a long time, it may show almost no symptoms or only signs that many owners mistakenly interpret as natural aging. In reality, however, PPID in horses is a dysfunction of the pituitary gland that leads to serious metabolic changes and a weakening of the entire body. Unfortunately, many horses are only seen by a veterinarian when the disease is already at an advanced stage. Early recognition of Cushing’s symptoms in horses allows for faster treatment and helps slow its progression before irreversible damage occurs.

Early Signs of PPID in Horses

The first signs of Cushing’s syndrome in horses are often subtle and easy to overlook. Owners may notice that their older horse has become less energetic, tires more quickly, or no longer looks as healthy as before. Over time, more characteristic symptoms begin to appear, which should raise concern:

• Difficulty shedding – the horse takes a long time to lose its winter coat or sheds unevenly. Thick patches of hair may remain on the back, neck, and legs even in warmer weather.
• Excessive hair growth (hirsutism) – the most recognizable symptom of PPID. The coat becomes long, curly, dull, and resembles a winter pony coat.
• Muscle loss, especially along the back and hindquarters – the horse may appear thin despite having a rounded belly.
• Change in body shape – the characteristic “pot-bellied” appearance results from weakened abdominal and back muscles, as well as metabolic disorders.
• Lethargy and apathy – the horse becomes less willing to move, reacts more slowly, avoids work, or tires easily.
• Excessive sweating – the horse sweats with minimal effort or even at rest.
• Increased thirst and frequent urination – signs of hormonal imbalance and excess cortisol affecting fluid regulation.
• Changes in skin and coat condition – the coat loses its shine, and the skin becomes thinner and more prone to infections, fungal issues, or abrasions.

Symptoms of Cushing’s syndrome in horses often appear gradually, which may cause owners to become accustomed to them and consider them normal for the horse’s age. However, each of these signs should prompt diagnostic testing. PPID in horses is not a death sentence—if diagnosed early. Early treatment of Cushing’s disease in horses significantly slows its progression and helps maintain good condition for many years.

Awareness and careful observation are the best forms of prevention. Any change in the behavior or appearance of an older horse may be the first sign of a hormonal problem—it is worth taking action before it is too late.

Advanced Symptoms of Cushing’s Syndrome in Horses

In the later stages of the disease, Cushing’s syndrome in horses (PPID) produces increasingly noticeable symptoms that affect the entire body. These signs become more visible and harder to ignore, and the horse often requires constant care and regular treatment. That is why it is so important for every owner of an older horse to recognize advanced symptoms of Cushing’s and distinguish them from the natural aging process.

Advanced Signs of PPID in Horses

• Laminitis – one of the most common and serious symptoms of PPID in horses. It can appear suddenly, even in horses that are not overweight and are on a proper diet. It results from hormonal and metabolic disturbances affecting blood circulation in the hooves. Any case of laminitis in an older horse should be a signal to test for PPID.
• Frequent infections – due to a weakened immune system, a horse with PPID becomes more prone to abscesses, skin infections, fungal diseases, gum inflammation, and respiratory issues. Even minor wounds heal more slowly.
• Metabolic disturbances – the horse may lose weight despite having a normal appetite or, conversely, accumulate fat around the crest of the neck, the base of the tail, and above the eyes. This is caused by hormonal imbalance and excess cortisol.
• Thermoregulation issues – horses with Cushing’s often feel cold in cooler weather despite being blanketed, and overheat easily in warmer months. Their bodies struggle to maintain a stable internal temperature.
• Poor overall appearance – a long, tangled coat, lack of shine, dull eyes, a “hunched” posture, and lethargy are common in horses with advanced PPID. Muscle loss and reduced topline tone can make the horse appear older than it actually is.

PPID vs Aging in Horses – How to Tell the Difference

For many owners, the symptoms of Cushing’s disease in horses may initially look like normal signs of aging. Indeed, some signs—such as slower shedding, reduced energy, or decreased muscle mass—can be misleading. The difference is that with hormonal disorders in horses, these changes progress faster, are more intense, and are harder to reverse without treatment.

If your horse:

• sheds much longer than other horses,
• sweats excessively, even in cooler weather,
• loses weight despite a good appetite,
• experiences recurring laminitis without an obvious cause—

this may indicate something more than normal aging.

Cushing’s syndrome in horses is a disease, not a natural stage of life. Early treatment of Cushing’s in horses, along with regular care, helps control symptoms and prevent complications. With proper therapy, a balanced diet, and attentive observation, a horse with PPID can enjoy a calm and active life for many years.

Symptoms of PPID in horses are the body’s way of signaling that it needs support. An experienced owner who can recognize these signals and does not ignore even small changes has a significant impact on the length and quality of their horse’s life. In the case of hormonal disorders, it is quick response and attentive care that determine whether a horse will maintain its health and strength for years to come.

Diagnosis of PPID

Diagnosing Cushing’s syndrome in horses (PPID) requires not only careful observation but, above all, accurate laboratory testing. The symptoms of this hormonal disorder can be very misleading—a horse may appear simply weak, old, or tired after winter, while its body is actually struggling with a serious endocrine condition. Early and precise diagnosis of PPID is crucial, because the sooner the disease is detected, the more effective the treatment of Cushing’s in horses will be, giving the animal a better chance at a long and comfortable life.

Why observation is not enough

Many owners notice symptoms of Cushing’s disease in horses only when the condition is already advanced. However, changes in the function of the pituitary gland begin much earlier—before the horse shows obvious signs such as abnormal shedding, muscle loss, or laminitis. Appearance and behavior alone are therefore not reliable indicators. Two older horses may present very differently—one may develop a thick, long coat, while another may only show a slightly slowed metabolism.

That is why the only way to confirm or rule out PPID in horses is through hormonal testing. These tests determine whether the pituitary gland is producing excessive amounts of ACTH, which is the key marker of this disease.

ACTH Test – the basic diagnostic tool

The most commonly used test in diagnosing Cushing’s syndrome in horses is the measurement of ACTH (adrenocorticotropic hormone) levels in the blood. This hormone, produced by the pituitary gland, stimulates the adrenal glands to release cortisol—the main cause of many of the disorders associated with PPID.

• In a healthy horse, ACTH levels fall within a normal range.
• In horses with PPID, these levels are significantly elevated.
• Blood samples are usually taken in the morning and sent to a specialized veterinary laboratory.

It is important to note that ACTH levels fluctuate throughout the year—they naturally increase in the autumn. Therefore, interpreting the results requires the expertise of a veterinarian. A high ACTH level is a strong indicator of PPID, but in some cases, additional confirmatory tests may be necessary.

TRH Stimulation Test – a complementary diagnostic tool

In cases where ACTH test results are inconclusive or symptoms are just beginning to develop, a veterinarian may perform a TRH stimulation test (thyrotropin-releasing hormone test). This involves administering TRH to the horse, which stimulates the pituitary gland to increase ACTH production. Blood samples are then taken before and after the administration of the substance.

• In healthy horses, the increase in ACTH levels is moderate.
• In horses with PPID, the response is excessive—ACTH levels rise sharply.

This test is more sensitive than the standard ACTH test and allows detection of the disease at a very early stage, before clear symptoms of Cushing’s disease in horses appear, such as a long coat, muscle loss, or laminitis.

Other supportive tests

To better assess the horse’s overall health and identify potential complications related to hormonal disorders, a veterinarian may recommend additional tests:

• Blood count and biochemistry – helps evaluate liver and kidney function, electrolyte and glucose levels, and the overall condition of the body.
• Urinalysis – allows assessment of fluid balance and potential protein loss.
• Insulin and glucose testing – since Cushing’s syndrome in horses often occurs alongside insulin resistance (EMS), which increases the risk of laminitis and metabolic disorders.

Diagnosing PPID requires consistency. Regular testing, especially in horses over 15 years of age, helps detect the disease before it causes permanent damage. As a result, treatment of Cushing’s disease in horses can be more effective, and the horse has a better chance of a longer, healthier life.

When should PPID testing be performed?

Testing should be carried out whenever a horse shows concerning symptoms, such as:

• prolonged shedding,
• excessive hair growth,
• sudden loss of muscle mass,
• laminitis without a clear cause,
• weakness or lethargy,
• frequent infections and skin inflammation.

Preventive testing is also recommended for all horses over 15 years of age, even if they do not show clear signs of disease. Early diagnosis allows treatment to begin at a stage when changes in the body are still reversible.

Monitoring hormone levels

PPID is a chronic condition, so regular monitoring of ACTH hormone levels is essential.

• Check-ups are usually performed every 3–6 months, and more frequently during the first year of treatment.
• This allows evaluation of treatment effectiveness and adjustment of medication doses, such as pergolide.
• Keeping a record of test results and observations can help track progress and respond in time.

Why is PPID diagnosis so important?

The earlier the disease is detected, the greater the chances of managing its effects. Early diagnosis helps to:

• prevent the development of laminitis,
• maintain proper muscle mass,
• control sugar and hormone levels,
• and most importantly, ensure a longer, healthier life for the horse.

PPID is not always visible to the naked eye. That is why regular testing and cooperation with a veterinarian are the best tools for a responsible owner who wants their horse to age with dignity rather than suffer in silence.

Treatment of Cushing’s Disease in Horses

Cushing’s syndrome in horses, known as PPID (Pituitary Pars Intermedia Dysfunction), is a chronic and progressive condition. However, with proper treatment, its symptoms can be effectively controlled, allowing the horse to maintain a good quality of life for many years. This requires consistency, close cooperation with a veterinarian, and adjusting the horse’s lifestyle to its individual needs. Well-managed therapy helps reduce the symptoms of Cushing’s disease in horses and prevents complications such as laminitis and weakened immunity.

Pharmacological Treatment – Pergolide (Prascend)

The foundation of treatment for Cushing’s disease in horses is pergolide, commonly known under the trade name Prascend. It belongs to a group of drugs called dopamine agonists, which help restore hormonal balance in the pituitary gland. In horses with PPID, dopamine levels naturally decrease, leading to overactivity of the pituitary gland and excessive production of ACTH. Pergolide compensates for this deficiency, reducing hormone overproduction and stabilizing the endocrine system.

How the treatment works:

• The medication is administered daily, orally, usually mixed with feed or given in a treat.
• The dosage is determined individually by a veterinarian based on ACTH test results and the horse’s response.
• Treatment typically begins with a low dose, which is gradually increased to minimize side effects.

Possible side effects:

At the beginning of treatment, some horses may show reduced appetite, lethargy, mild colic, or mood changes. These symptoms usually subside after a few days. If they persist, the veterinarian may temporarily reduce the dose.

Duration of treatment:

PPID treatment is lifelong. The disease cannot be completely cured, but its progression can be effectively managed. After 4–6 weeks of treatment, horses often regain energy, and improvements can be seen in coat condition, appetite, and overall well-being.
ACTH levels should be monitored every 3–6 months to evaluate treatment effectiveness and adjust the dosage if necessary.

Supportive Treatment and Natural Methods

Pharmacotherapy is the foundation, but effective treatment of Cushing’s disease in horses also includes natural support, proper nutrition, and a consistent daily routine.

1. Herbs and natural supplements

Some natural substances can support horses with PPID by helping stabilize hormones and improve immunity:

• Zinc, magnesium, vitamin E – support the nervous system and immune function.
• Coenzyme Q10, spirulina – act as antioxidants and support cellular regeneration.
• Ginkgo biloba, ashwagandha, ginseng – improve circulation and help regulate hormonal balance.
• Echinacea, rockrose (Cistus), nettle – strengthen immunity and reduce the risk of infections.

All supplements should be used with caution and after consultation with a veterinarian, especially if the horse is receiving pergolide.

2. Diet for a horse with PPID

Proper nutrition is the foundation of health in horses with hormonal disorders. Excess sugar and starch can worsen the symptoms of Cushing’s disease and increase the risk of laminitis.

Basic dietary principles:

• High fiber intake – good-quality hay or chopped forage should form the basis of the diet.
• Limit oats and high-starch grains – replace them with low-sugar feeds designed for metabolic horses.
• Regular feeding – frequent, small meals help prevent insulin spikes.
• Supportive additions – flaxseed, black seed oil, brewer’s yeast, and probiotics support gut health and digestion.
• Avoid high-sugar pasture (NSC) – especially in spring and autumn, when the risk of laminitis is highest.

3. Laminitis and hoof management

Laminitis is one of the most serious complications of hormonal disorders in horses and requires special attention:

• Regular hoof trimming every 4–6 weeks.
• Soft, resilient footing in the stall and turnout areas.
• Daily light exercise to support circulation.
• Immediate veterinary consultation in case of lameness or stiffness.

4. Stress Reduction and Proper Living Conditions

Stress increases cortisol levels and worsens the course of PPID in horses. Therefore, horses with Cushing’s should be provided with a calm and predictable environment:

• A consistent daily routine and avoidance of sudden changes.
• Regular contact with other horses – this improves mood and reduces stress.
• Plenty of time outdoors – ideally in a spacious, well-ventilated paddock.
• Minimizing noise, tension, and frequent changes of stable.

Movement is essential—light training, walks, and groundwork help maintain muscle condition, improve circulation, and support metabolism.

Treating Cushing’s disease in horses is a process that requires patience but brings significant results. Combining pergolide therapy with proper nutrition, supplementation, and daily care allows older horses to remain in good condition for many years.

The owner plays the most important role—recognizing early changes, responding to declines in well-being, and working closely with a veterinarian. With the right knowledge and care, Cushing’s syndrome in horses is no longer a sentence, but a manageable condition—one that allows for a calm, mindful, and balanced life.

Diet and Nutrition for a Horse with PPID

Proper nutrition for a horse with Cushing’s syndrome (PPID) is one of the most important elements of both treatment and prevention. PPID affects the entire hormonal and metabolic system of the body. It disrupts the processing of sugars, fats, and proteins, making horses more prone to fluctuations in blood glucose levels, muscle loss, and secondary conditions such as laminitis. Therefore, a well-balanced diet is essential for effective management of Cushing’s disease in horses and for maintaining good overall condition.

Improper feeding can worsen the symptoms of Cushing’s disease, lead to metabolic disturbances, and, in severe cases, result in serious complications. The key is to provide energy in a safe form while maintaining a balance between fiber, fats, and low sugar intake.

1. Low-sugar and low-starch feeds

Horses with PPID often also suffer from equine metabolic syndrome (EMS) or insulin resistance, so their diet should be low in sugars and starch. Excess carbohydrates cause sharp spikes in glucose and insulin levels, which can worsen the disease and increase the risk of laminitis.

• Choose feeds labeled low starch or low sugar—their NSC (sugar + starch) content should be below 10–12%.
• Avoid oats and high-calorie grains—replace them with low-sugar mixes, unmolassed beet pulp, alfalfa chaff, or grass pellets.
• If additional energy is needed, provide it from fats (e.g., flaxseed oil, rapeseed oil, or rice bran oil), rather than carbohydrates.

Such feeding helps stabilize blood glucose levels, which is crucial in managing hormonal disorders like PPID.

2. High fiber intake – the foundation of health

Fiber is essential for proper digestive function and for stabilizing blood sugar levels. An older horse with PPID should have constant access to hay or pasture, but the quality must be carefully monitored.

• Hay must be free of dust and mold—soaking or steaming it can help reduce sugar content.
• For horses prone to weight gain, limit the amount of hay without restricting access—slow-feeding nets are ideal to prolong chewing time.
• During grazing season, avoid young, lush grass—it contains high sugar levels, especially in spring and autumn.

Fiber also supports saliva production, which helps neutralize stomach acids and protects against ulcers—an issue to which horses with PPID are particularly prone.

3. Limiting or eliminating oats

Oats are an energy-rich feed, but they are also high in starch—which can cause spikes in glucose and insulin levels, making them particularly risky for horses with PPID.

Instead of oats, it is better to use:

• low-starch feeds designed for horses with PPID or EMS,
• alfalfa chaff, grass chaff, or rice bran,
• unmolassed beet pulp,
• fat sources such as flaxseed oil, rice bran oil, or coconut oil.

This approach provides energy gradually, without the risk of metabolic disturbances.

4. Supplements supporting immunity and the nervous system

Managing Cushing’s disease in horses requires supporting overall health and condition. It is beneficial to supplement the diet with nutrients and minerals that aid metabolism, immunity, and the nervous system:

• Vitamin E – a powerful antioxidant that supports the nervous system and muscles.
• Magnesium, zinc, and chromium – help regulate sugar metabolism and stabilize insulin levels.
• Omega-3 fatty acids (flaxseed oil, black seed oil) – have anti-inflammatory effects and support immunity.
• Probiotics and brewer’s yeast – support gut flora and improve nutrient absorption.
• Adaptogenic herbs – ashwagandha, ginseng, ginkgo biloba – support the hormonal system and help the horse cope with stress.

5. Regular feeding and dietary control

Horses with PPID should be fed frequently but in small portions—ideally 4–5 times a day. This helps maintain stable energy and blood sugar levels. Keeping a feeding journal is also useful, where you record types of feed, quantities, and the horse’s reactions. This makes it easier to monitor the diet and quickly detect any irregularities.

6. Constant access to water and mineral salt

A horse with Cushing’s syndrome often drinks more due to increased urination. It must therefore have constant access to clean, fresh water and a natural salt lick without added sugars or molasses.

The diet of a horse with PPID should be natural, low in sugar, and rich in fiber. The key is balance—providing enough energy without overloading the metabolism. Proper nutrition not only reduces the symptoms of Cushing’s disease in horses but also supports immunity, improves coat condition, and stabilizes hormonal function.

With a well-balanced diet, regular monitoring, and a patient owner, an older horse with PPID can live a long, healthy, and active life—free from pain and complications associated with this hormonal disorder.

Daily Care for a Horse with PPID

Caring for a horse with Cushing’s syndrome (PPID) is a daily responsibility that requires patience, careful observation, and consistency. Although PPID is a chronic and progressive condition, proper care allows a horse to remain in good condition for many years. The key is to create an environment where the horse’s body is not additionally burdened by stress, cold, or excessive effort. With the right approach, even an older horse with PPID can enjoy a calm and comfortable life.

1. Exercise and physical activity

Movement is essential—even for horses with PPID. Moderate activity helps maintain muscle mass, supports circulation, improves metabolism, and strengthens the immune system. However, overly intense training can have the opposite effect, especially in horses showing symptoms such as weakness, excessive sweating, or susceptibility to laminitis.

Training guidelines for a horse with PPID:

• Focus on daily but moderate activity—hand walking, groundwork, lunging, or light recreational riding.
• Avoid overloading—short, calm sessions with breaks are better than one long workout.
• Proper warm-up and cool-down are essential—horses with PPID often have stiff muscles and adapt more slowly to temperature changes.
• If signs of laminitis appear (lameness, warm hooves, reluctance to move), stop exercise immediately and consult a veterinarian.

Outdoor movement is just as important as medical treatment. Regular walks help maintain a healthy weight and improve overall well-being.

2. Coat and skin care

One of the most characteristic symptoms of Cushing’s disease in horses is a long, dense coat (hirsutism) and shedding problems. Proper coat and skin care is not only about appearance but also about health and comfort.

Daily care should include:

• Regular brushing to remove dead hair, improve circulation, and prevent overheating.
• Washing or wiping with a damp cloth—especially in areas prone to sweating (neck, belly, hindquarters).
• Clipping—helpful for horses that do not shed properly, making temperature regulation easier.
• Gentle grooming products—antibacterial shampoos and antifungal treatments help maintain healthy skin.

Routine grooming also allows for early detection of wounds, infections, or skin issues, which are more common in horses with weakened immunity.

3. Hoof care and trimming

Hooves are a reflection of a horse’s overall health, and in horses with PPID they require special attention. Hormonal imbalances affect metabolism and circulation, increasing the risk of laminitis.

Hoof care guidelines:

• Regular trimming every 4–6 weeks to maintain proper hoof balance.
• Daily monitoring of hoof temperature and firmness—any warmth or increased pulse may signal early laminitis.
• Soft footing in the stable and turnout areas to reduce strain and prevent injuries.
• In cases of laminitis, close cooperation between the farrier and veterinarian is essential—corrective shoeing or supportive pads can significantly improve comfort.

4. Protection from cold and overheating

Hormonal disorders also affect thermoregulation—horses with PPID may easily become cold in winter and overheat in summer.

In winter:

• Provide a warm, dry blanket (especially if the horse is clipped or has a thin coat).
• Avoid drafts and moisture in the stable.
• Check regularly that the horse is not sweating under the blanket—overheating weakens the immune system.

In summer:

• Avoid work during high temperatures; provide shade and good ventilation.
• Ensure constant access to fresh water.
• Use lightweight mesh sheets if needed to protect from sun and insects.

5. The importance of routine and a calm environment

PPID in horses leads to increased cortisol production—the stress hormone. That is why calmness and stability are just as important as medication.

How to reduce stress:

• Maintain a consistent daily routine—feeding, grooming, and exercise at the same times each day.
• Provide contact with other horses—social isolation negatively affects mental well-being and increases apathy.
• Avoid frequent changes of stall, stable, or environment.
• Adjust workload and training intensity to the horse’s current condition.

A calm routine helps lower cortisol levels, improves immunity, and stabilizes hormonal balance—it is a natural part of managing Cushing’s disease in horses.

6. Regular veterinary care

Cushing’s syndrome in horses requires ongoing veterinary monitoring. Regular check-ups help track ACTH levels, adjust treatment, and respond quickly to any decline in health.

Recommended actions:

• ACTH testing every 3–6 months.
• Dental check-ups at least once a year—horses with PPID often have weaker teeth.
• Up-to-date vaccinations and deworming.
• Ongoing observation for infections, wounds, inflammation, and laminitis.

Daily care for a horse with PPID is more than routine—it is attention to every detail, from diet and exercise to emotional well-being and stable conditions. Hormonal disorders require a comprehensive approach, but with proper support, a horse with Cushing’s can live a long, active, and pain-free life.

The most important “medicine” for these horses is the owner’s patience, empathy, and consistency. These qualities help them maintain calmness, health, and joy of life—despite the disease.

Living with a Horse with Cushing’s – What to Expect

Living with a horse diagnosed with Cushing’s syndrome (PPID) does not mean the end of shared activities, riding, or the everyday joy of being with your horse. Although PPID is a chronic condition that requires ongoing care, most horses—with proper treatment and attentive management—can live long, active, and happy lives. The key is understanding your horse’s limitations, adjusting the workload, and being mindful of its daily needs.

A Horse with PPID Can Still Be Active

Many owners fear that a PPID diagnosis means the end of training or riding. In reality, most horses, once properly treated and fed a balanced diet, regain energy, enthusiasm, and willingness to move.

• Horses with a mild form of the condition can take part in light recreational riding, dressage training, or relaxed trail rides.
• Older or weaker horses often benefit from groundwork—balance exercises, stretching, pole work, or simply walking.
• Physical activity improves circulation, supports metabolism, and helps prevent muscle loss—crucial in hormonal disorders.

The most important thing is to adjust the intensity to the horse’s condition. Days when the horse feels more lethargic are a natural part of living with PPID. Patience and observation matter more than any training plan.

PPID Is Not the End – It’s a New Rhythm of Life

Treatment of Cushing’s disease in horses allows them to function well for many years, provided they live in calm and predictable conditions. Horses with PPID are sensitive to stress, noise, sudden changes, and excessive effort—but they respond very well to routine, stability, and a gentle approach.

For many owners, caring for a horse with PPID becomes a unique experience. The condition teaches patience, attentiveness, and sensitivity. Observing daily changes in behavior, appetite, or coat condition allows for quicker responses and strengthens the bond between horse and human.

Horses with PPID often become especially gentle and appreciative. While they may not always be able to compete or train intensively, they can still be wonderful companions, teachers, and friends. Walks, grooming, and calm groundwork can be just as rewarding as riding.

Strength in Understanding and Patience

Living with a horse with PPID is a new chapter—slower, calmer, but full of connection. Consistency, care, and observation bring results that can be truly surprising—a horse may regain brightness in its eyes, flexibility in movement, and a willingness to engage.

Understanding the nature of the condition and providing thoughtful care largely determine the horse’s quality of life. How long and how comfortably an older horse with Cushing’s syndrome lives depends greatly on the owner’s empathy and consistency.

Every small gesture—grooming, a walk, a quiet moment together—has immense value. Cushing’s syndrome in horses does not take away the joy of life, as long as the horse has a person who understands its needs. Often, the illness becomes the beginning of a new kind of relationship—built on trust, gentleness, and genuine care.

Because a horse with PPID can be happy. It just needs an owner who believes that patience, calmness, and care can do more than any medication.

Prevention and Early Detection

In the case of Cushing’s syndrome (PPID), prevention is just as important as treatment itself. The disease develops slowly and may not show clear symptoms for a long time. That is why early recognition largely depends on the owner’s awareness and attentiveness. The earlier PPID is detected, the greater the chance that the horse will maintain good condition, energy, and quality of life for years to come.

How to recognize early signs of PPID

Early symptoms of PPID are often subtle and non-specific, which is why many owners do not immediately associate them with a hormonal disorder. Sometimes the horse simply seems “lazier,” has a “difficult coat,” or sheds poorly. In reality, this is the best moment to take action.

Be alert if your horse:

• sheds longer than usual or has an uneven coat,
• sweats more frequently, even with light effort,
• becomes more lethargic or apathetic,
• loses topline muscle while developing a “pot-bellied” appearance,
• has recurring laminitis without a clear cause,
• gets sick more often (skin infections, abscesses, gum issues),
• or drinks and urinates more than before.

Even mild symptoms are a signal to perform an ACTH test and consult a veterinarian. A simple blood test can detect the disease before permanent damage occurs.

The importance of screening after age 15

With age, the risk of PPID increases significantly—estimates suggest that 20–30% of horses over 15 may be affected. That is why regular preventive testing is essential.

• Every horse over 15 should have ACTH levels tested at least once a year, even without clear symptoms.
• In autumn, when hormone levels naturally rise, it is worth repeating the test to confirm results remain within seasonal norms.
• Horses with a history of laminitis, shedding issues, or muscle loss should be tested more frequently—even every 6 months.

The cost of ACTH testing is small compared to the consequences of late diagnosis. Early detection allows for timely treatment with pergolide and helps prevent complications such as chronic laminitis and weakened immunity.

Owner awareness – the key to a horse’s health

Whether a horse with PPID is diagnosed early largely depends on the owner. They see the horse every day, know its habits and behavior, and can notice subtle changes others might miss.

That is why it is important for horse owners to:

• know the most common symptoms of PPID,
• keep notes on behavior, appetite, coat condition, and activity,
• never ignore small changes such as delayed shedding or excessive sweating,
• consult a veterinarian instead of waiting to see if symptoms “go away.”

Awareness and prevention are the most powerful tools in managing PPID. With them, the disease does not have to limit a horse’s life—it simply becomes part of daily routine.

Cushing’s syndrome (PPID) changes a horse’s life—but it does not have to define it. A diagnosis is not the end of shared work, but the beginning of a new chapter based on understanding, care, and daily attentiveness. Although PPID is a chronic condition, with proper treatment, nutrition, and a calm lifestyle, a horse can live for many years in good condition, free from pain and suffering.

Many owners admit that caring for a horse with Cushing’s teaches more than discipline—it brings humility, patience, and deep empathy for an animal that trusts them completely. A horse with PPID does not need pity, but support and stability. It simply needs a human who is there every day—observing, responding, and adapting care to its needs.

The key to successfully managing PPID is regular diagnosis, consistency in treatment, and daily observation. There is no single solution for every horse—each responds differently, and the best results come from an individualized approach and close cooperation with a veterinarian.

It is worth remembering that a horse’s health begins with an informed owner. Their knowledge, awareness, and responsibility determine whether the disease is detected early and whether treatment will be effective.

PPID is a challenge—but also proof that care and love can be stronger than illness.

Because a horse with Cushing’s can live a long, calm, and happy life—if it has someone who truly understands it.
