What signs might indicate a horse is dehydrated?

• A. Dull or dry gums, reduced skin elasticity, listlessness, reduced urination or sweating, and sunken eyes in severe cases.
• B. Very wet gums and high energy.
• C. Bright, sticky saliva.
• D. Increased appetite.

Answer: (A)

Recognising dehydration in a horse comes down to changes you can see in the mouth, skin, energy, urine and sweating, and the eye area. Dull or dry gums show the mouth isn’t well moisturised because fluids are low. Skin that tugs and takes longer to spring back when you pinch it (skin elasticity) also points to reduced body fluids. When a horse is dehydrated, you’ll often see them seeming listless or less lively, because their body isn’t circulating fluids as efficiently. Decreased urination or reduced sweating are classic signs that the body is conserving water. In more advanced cases, the eyes can look sunken as the overall fluid balance drops.

Other options don’t fit dehydration as clearly. Very wet gums and high energy suggest good hydration or activity rather than fluid deficit. Bright, sticky saliva isn’t a definitive dehydration sign on its own, and increased appetite isn’t related to dehydration. If dehydration is suspected, offer water gradually and seek veterinary advice, especially if there are multiple signs or the horse won’t drink.
