Why is my Arabian sweating too much?
If your Arabian horse is sweating more than normal, you are likely concerned. Excessive sweating, or hyperhidrosis, is not normal and often points to an underlying issue. The first step is to rule out simple causes like high heat or intense exercise. But if your horse is sweating at rest or in cool conditions, it is time to investigate further. Common reasons include pain, hormonal imbalances such as pituitary pars intermedia dysfunction (PPID, also known as Cushing’s disease), infections, or stress. A prompt vet check is essential to identify the root cause and ensure your horse’s comfort and health.
Common Causes of Excessive Sweating in Arabians
Pain and Discomfort
Arabians are stoic, so pain from colic, arthritis, or laminitis can trigger sweating without obvious signs. Look for other symptoms like pawing, flank watching, or reluctance to move. Dental issues or muscle soreness can also cause sweating. If you suspect pain, contact your vet for a thorough exam.
Hormonal Imbalances (PPID)
PPID is common in older horses and can cause a long, curly coat and excessive sweating. Even younger Arabians can develop it. A simple blood test (ACTH level) can diagnose PPID. Treatment with pergolide is often effective. If your horse is a heavy sweater and over 15 years old, PPID should be a top consideration.
Infections and Fever
A bacterial or viral infection, such as pneumonia or EPM, can cause a fever and sweating. Check your horse’s temperature (normal is 99-101°F). Other signs include lethargy, nasal discharge, or coughing. Infections require immediate veterinary attention.
Stress and Anxiety
Arabians are sensitive and prone to stress from changes in routine, new environments, or training pressure. Stress sweating often occurs during travel or competition. Provide a calm, consistent routine and consult a trainer if behavior issues persist.
When to Call Your Veterinarian
Call your vet if your Arabian is sweating excessively for more than a few hours, especially if accompanied by other signs like sweating while at rest, breathing heavily, or showing pain. Also, if the sweat is localized to one area (unlike generalized sweating), it could indicate a nerve issue. Your vet may run bloodwork, check for Cushing’s, or perform a physical exam. Do not try to diagnose or treat at home without professional guidance.
Management Tips While Waiting for the Vet
- Keep your horse cool with fans or shade.
- Offer plenty of fresh water and electrolytes.
- Avoid riding or stressing the horse.
- Monitor temperature and heart rate.
- Note any other symptoms to report to your vet.
Remember, excessive sweating is a sign, not a diagnosis. Partner with your vet to find the cause and get your Arabian back to feeling its best.
Key Takeaway
Excessive sweating in Arabians is a red flag for underlying issues like pain, Cushing’s, or infection; always have a vet diagnose the cause.
