How to Check the Hydration of a Horse

You can check the hydration of your horse in several ways: by measuring capillary refill time (CRT), checking skin turgor, and assessing eyes and gums.

Instructions

  1. Measure Capillary Refill Time

    • 1

      Use both hands to part the horse's lips and expose the gums.

    • 2

      Press gently and briefly on the gum of the upper jaw with the index finger or thumb of one hand. This will force the blood from the capillaries, "blanching" the gum.

    • 3

      Watch and count how long it takes for the gum to return to its natural pink color after removing your finger. If the count is longer than 2 seconds, your horse may be dehydrated or have a circulatory problem.

    • 4

      Take this measurement regularly to get an idea of what's normal for your horse.

    Assess Eyes and Gums

    • 5

      Learn what your horse's eyes and gums normally look like. They should appear moist and shiny, not dry.

    • 6

      Inspect your horse's gums and eyes frequently.

    Check Skin Turgor

    • 7

      Pinch the skin on the horse's neck in front of the shoulder, using your thumb and forefinger.

    • 8

      Note whether the skin snaps back to its normal position quickly or responds slowly and remains "tented up." A slow response can indicate dehydration.

    • 9

      Check skin turgor regularly to get an idea of what's normal for your horse. Individuals can show variation in this test.
