When a horse is sweating without physical exertion, it can indicate several underlying issues, ranging from stress and anxiety to more serious medical conditions like pain, fever, or hormonal imbalances. Monitoring the circumstances surrounding the sweating and observing other symptoms can help determine the cause and whether veterinary attention is needed.
Why Is My Horse Sweating Excessively?
Excessive sweating in horses, also known as hyperhidrosis, can be triggered by various factors. While sweating is a natural cooling mechanism during physical activity or hot weather, unexplained sweating without exertion warrants closer inspection. Here are some potential reasons:
Stress and Anxiety
Horses are sensitive animals, and stressful situations can lead to physiological responses, including sweating.
- New Environments: A new stable, trailer ride, or unfamiliar surroundings can cause anxiety.
- Separation Anxiety: Being separated from companions can induce stress.
- Loud Noises: Fireworks, thunderstorms, or construction can be frightening.
Pain
Pain is a significant cause of sweating in horses, even without physical activity.
- Colic: Abdominal pain can cause profuse sweating, along with other signs like restlessness and pawing.
- Laminitis: Inflammation of the laminae in the hooves is extremely painful and can cause sweating, especially in the lower legs.
- Musculoskeletal Issues: Arthritis, muscle strains, or other injuries can lead to chronic pain and sweating.
Fever and Infection
An elevated body temperature due to infection can also cause a horse to sweat.
- Respiratory Infections: Pneumonia or equine influenza can cause fever and sweating.
- Abscesses: Internal or external abscesses can lead to a systemic inflammatory response and sweating.
- Other Infections: Any systemic infection can potentially cause a fever and subsequent sweating.
Hormonal Imbalances
Hormonal issues, such as those associated with Equine Cushing’s Disease (Pituitary Pars Intermedia Dysfunction or PPID), can disrupt normal body functions, including sweating.
- PPID: This condition is common in older horses and can cause excessive sweating, along with a long, curly coat that doesn’t shed properly.
- Thyroid Issues: Although less common, thyroid imbalances can also affect sweating.
Other Medical Conditions
Certain other medical conditions can also lead to unexplained sweating.
- Neurological Issues: Conditions affecting the nervous system can disrupt normal sweating regulation.
- Metabolic Disorders: Some metabolic disorders can cause imbalances that lead to sweating.
What Should I Do If My Horse Is Sweating Without Exertion?
If you notice your horse sweating without a clear reason, here are some steps to take:
- Check Vital Signs: Take your horse’s temperature, heart rate, and respiration rate. Elevated readings can indicate fever, pain, or stress.
- Observe Behavior: Look for other signs of discomfort, such as restlessness, pawing, or decreased appetite.
- Assess Environment: Ensure the horse is in a comfortable environment, away from stressors.
- Call the Vet: If the sweating is profuse, persistent, or accompanied by other symptoms, consult your veterinarian to determine the underlying cause and appropriate treatment.

How Can I Tell If My Horse Is Stressed?
Signs of stress in horses include increased heart rate, rapid breathing, dilated nostrils, tense muscles, and changes in behavior such as pacing, tail swishing, or reluctance to move. Recognizing these signs early can help you address the source of stress and prevent further issues.
What Is Equine Cushing’s Disease (PPID)?
Equine Cushing’s Disease, or Pituitary Pars Intermedia Dysfunction (PPID), is a hormonal disorder common in older horses. It results from an overactive pituitary gland, leading to symptoms like a long, curly coat that doesn’t shed properly, increased drinking and urination, lethargy, and increased susceptibility to infections.
Can Pain Cause a Horse to Sweat?
Yes, pain is a significant cause of sweating in horses. Conditions like colic, laminitis, arthritis, and muscle injuries can all cause a horse to sweat, even without physical exertion. If your horse is sweating and showing other signs of discomfort, it’s essential to consult a veterinarian to diagnose and manage the pain.
What Are the Normal Vital Signs for a Horse?
Normal vital signs for a horse include a temperature of 99-101.5°F (37.2-38.6°C), a heart rate of 28-44 beats per minute, and a respiration rate of 8-16 breaths per minute. Deviations from these ranges can indicate underlying health issues that require veterinary attention.
Unexplained sweating in horses can stem from various causes, including stress, pain, fever, and hormonal imbalances. Promptly identifying the cause and seeking veterinary care when necessary can help ensure your horse’s health and well-being. Want to discover more about horse health and management?
