Dehydration in horses can be subtle, especially in cold weather when their thirst drive decreases. Recognizing the signs early is crucial for their health. Key indicators include dry gums, reduced skin elasticity (skin tenting), lethargy, and decreased urine output. Addressing dehydration promptly can prevent serious complications.
What Are the Key Signs of Dehydration in Horses in Winter?
Dehydration occurs when a horse loses more fluids than it takes in, disrupting essential bodily functions. In cold weather, horses may drink less water, increasing their risk of dehydration. Recognizing the signs early can help prevent severe health issues.
Reduced Skin Elasticity (Skin Tenting)
One of the most common signs of dehydration is reduced skin elasticity. To check this, gently pinch a small area of skin on the horse’s neck or shoulder. If the horse is well-hydrated, the skin should quickly snap back into place. In a dehydrated horse, the skin will return to its normal position more slowly, or "tent" before slowly returning.
Dry or Tacky Gums
A healthy horse has moist gums. Dehydrated horses often have dry or tacky gums. To check, lift the horse’s upper lip and feel the gums with your finger. If they feel sticky or dry, it’s a sign that the horse may be dehydrated.
Lethargy and Weakness
Dehydration can cause a horse to become lethargic or weak. You might notice that the horse is less energetic than usual, reluctant to move, or tires easily during exercise. Lethargy is a general sign of illness, but when combined with other symptoms, it can indicate dehydration.
Decreased Urine Output
A healthy horse urinates regularly. A decrease in urine output can be a sign of dehydration. It may be difficult to monitor urine output directly, but you can observe the frequency and volume of urination when the horse is in its stall or paddock.
Sunken Eyes
Sunken eyes can be a sign of moderate to severe dehydration in horses. The area around the eyes may appear hollow or more deeply set than usual. This is because the tissues around the eyes lose moisture and volume when the horse is dehydrated.
Elevated Heart Rate
Dehydration can cause an elevated heart rate as the horse’s body tries to compensate for the reduced blood volume. A normal resting heart rate for a horse is typically between 28 and 44 beats per minute. If you suspect dehydration, taking your horse’s heart rate can provide valuable information.
How Can You Encourage a Horse to Drink More Water in Cold Weather?
- Provide fresh, clean water: Ensure water is always available and free of ice.
- Offer warm water: Some horses prefer warm water in cold weather.
- Add electrolytes: Electrolytes can stimulate thirst.
- Soak feed: Wetting hay or feed can increase water intake.

How quickly can a horse become dehydrated?
A horse can become dehydrated in a matter of hours, especially if it is exercising heavily or if the weather is hot or cold. Factors like access to water, humidity, and the horse’s overall health play a significant role in the rate of dehydration. Regular monitoring and ensuring constant access to fresh water are essential to prevent rapid dehydration.
Can dehydration cause colic in horses?
Yes, dehydration is a significant risk factor for impaction colic in horses. When a horse is dehydrated, the intestinal contents can become dry and compacted, leading to a blockage. Ensuring adequate water intake, especially during colder months, can help maintain proper gut motility and reduce the risk of colic.
What are the long-term effects of chronic dehydration in horses?
Chronic dehydration can lead to various long-term health problems in horses, including kidney damage, decreased performance, and an increased risk of impaction colic. Persistent dehydration can also affect the horse’s overall well-being and vitality. Consistent access to fresh water and a balanced diet are crucial for preventing these long-term effects.
Recognizing the signs of dehydration in horses during cold weather is essential for maintaining their health and well-being. By staying vigilant and taking proactive measures to encourage water intake, you can help your horse stay hydrated and healthy throughout the winter months.
