Instructions
Detecting Dehydration
Evaluate the mucous membranes of your horse's mouth and tongue. If they are excessively dry and red, the horse is showing signs of dehydration. Check the horse for excessive sweating, dull or sunken eyes and depression.
Push on the horse's gums above the teeth to check for prolonged capillary refill time. The skin will change from pink to white as you push. Count how many seconds it takes for the color to return. Anything longer than three seconds indicates dehydration.
Check your horse's heart rate. Normal heart rate is between 36 and 42 beats per minute, according to Equine Veterinary Services. Anything higher than 60 beats per minute indicates dehydration.
Perform the "skin-tent test," as the horse's degree of dehydration can be estimated by testing skin elasticity. Fold a section of skin of the horse's lower chest. Normally, it should spring back into place as soon as you let it go. In horses with moderate to severe dehydration, the skin stays up in a ridge or returns very slowly.
Record your horse's respiration rate. Normal respiration rate in a healthy horse is eight to 12 breaths per minute. The respiration rate of a dehydrated horse will be higher than the normal rate, and the breaths will be shallow.
Treating Dehydration
Give your horse small amounts of clean, fresh water at frequent intervals if he is mildly dehydrated.
Give your horse electrolyte supplements in her feed if she is deficient in electrolytes, minerals that are vital to nerve and muscle function. A horse with low electrolyte levels is fatigued and nervous; the animal's muscles will be stiff and may develop tremors. Your veterinarian should evaluate your horse and determine the proper supplement dosage.
Call the veterinarian if your horse is moderately to severely dehydrated. The vet may administer corrective replacement solutions via a nasogastric tube or intravenous solutions through the jugular vein.
Provide clean, fresh water and mineral blocks to the horse at all times to prevent dehydration. Monitor the amount of water the horse consumes every day.
Deworm your horse on a regular schedule. Worms can block a horse's intestines and make healthy hydration impossible.
Place a tank heater in your horse's water bucket or use a heated water bucket to keep the water supply from freezing in cold weather.
