Signs of Cushing’s Disease in Horses 🩺

Cushing’s disease, also known as Pituitary Pars Intermedia Dysfunction (PPID), is a common endocrine disorder in older horses. Early detection and management are crucial for maintaining the health and quality of life of affected horses. Here are the key signs and symptoms to watch for.

1. Abnormal Coat Changes 🐴

Long, Curly Coat

One of the most noticeable signs of Cushing’s disease is the development of a long, curly coat that does not shed properly, even in warm weather.

Delayed Shedding

Horses with Cushing’s disease often have delayed shedding of their winter coat, resulting in a thick, woolly appearance throughout the year.

2. Excessive Drinking and Urination 💧

Increased Thirst

Affected horses may exhibit increased thirst, often drinking more water than usual.

Frequent Urination

Along with increased drinking, these horses tend to urinate more frequently, which can lead to wet bedding and increased stall maintenance.

3. Weight Loss and Muscle Wasting ⚖️

Muscle Loss

Cushing’s disease can cause significant muscle wasting, particularly along the topline, leading to a pot-bellied appearance.

Weight Loss

Despite having a good appetite, horses with Cushing’s disease may lose weight due to muscle wasting and changes in metabolism.

4. Laminitis 🦶

Chronic or Recurrent Laminitis

Cushing’s disease increases the risk of laminitis, a painful and potentially debilitating condition affecting the hooves. This can present as recurrent episodes of lameness or chronic hoof pain.

5. Lethargy and Reduced Performance 😴

Decreased Energy Levels

Horses with Cushing’s disease often show signs of lethargy, decreased stamina, and reduced interest in physical activity.

Poor Performance

Owners may notice a decline in performance levels, particularly in previously active or competitive horses.

6. Fat Deposits and Abnormal Sweating 🥵

Fat Pads

Affected horses may develop abnormal fat deposits, particularly around the eyes, along the neck (cresty neck), and over the tail head.

Excessive Sweating

Cushing’s disease can cause irregular sweating patterns, including excessive sweating without obvious cause or during cool weather.

7. Recurrent Infections and Poor Healing 🦠

Susceptibility to Infections

Horses with Cushing’s disease often have a compromised immune system, making them more susceptible to infections, such as skin infections and hoof abscesses.

Slow Healing

Wounds and infections may heal more slowly than usual, requiring additional veterinary care and management.

8. Behavioral Changes 🧠

Increased Appetite

Despite weight loss, horses with Cushing’s disease may exhibit an increased appetite, often appearing hungry or constantly seeking food.

Behavioral Shifts

Owners may notice changes in behavior, such as increased irritability or changes in social interactions with other horses.

Conclusion 🏆

Recognizing the signs of Cushing’s disease in horses is crucial for early diagnosis and effective management. If you observe any of these symptoms in your horse, consult your veterinarian for a thorough examination and appropriate testing. Early intervention and proper treatment can significantly improve the quality of life for horses with Cushing’s disease.
