As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

Hydration Hay Original Horse Hay Block is a blend of quality grass and alfalfa that has been compressed into a convenient lightweight block. Simply drop the block into a bucket of water and it will quickly absorb water to make moist, palatable hay. A great way to deliver consistent, quality nutrition in a convenient, lightweight, easy-to-feed compressed block that horses love! 

Place one 2-lb Hydration Hay Horse Hay Block in a large bucket. Add a minimum of 5.5 quarts of water. Allow product to absorb water prior to feeding (approximately 10 minutes). Recommended for all horses at all life stages.
Favorite Features

Hydration Hay Promotes Water Intake for Proper Hydration.
Traveling can be stressful and many horses struggle to take in the proper amount of water on the road. Hydration Hay gives you horse consistent, quality forage while giving them the proper hydration they need.

Convenient, Lightweight, and Easy to Use
Carrying, feeding, and traveling with heavy hay bales is messy and inconvenient. Hydration Hay makes feeding on the go easy. The blocks are compressed so they take up less room in your truck or trailer and each one only weighs about 2 pounds.

Quickly Absorbs Five Quarts of Water
Each block soaks up five quart of water making moist, palatable, and hydrating hay.

Compressed Blend of Premium Grass and Alfalfa Hay
Contains consistent, quality grass and alfalfa hay that provide the nutritious roughage horses need.

Reduces the Need to Haul Water and Large Bales of Hay When Traveling
Most horses prefer the taste of their water from home But Hydration Hay hides the "strange" taste of unfamiliar water, so you can use local water when on the road. Say goodbye to the days of lugging large, heavy bales of hay and water from home!

Convenient Way to Deliver Oral Medications and Supplements
The moist hay is a great way to get oral medications, dewormers, and supplements into your horse.
Please consult your veterinarian prior to administering any medications.

Instructions for Use:
Hydration Hay® Horse Hay Blocks can be fed dry or soaked in water.

Soaking Directions:

Place one 2-lb block in a large bucket. Add a minimum of 5 quarts of water. Allow product to absorb water prior to feeding (approximately 10 minutes). To facilitate more uniform absorption, flip the hay block halfway through soaking time.
Additional mixing by hand may further accelerate water absorption.

Designed to replace a portion or all of the forage in a horse’s diet. Replace forage on a 1:1 ratio. Each 2 pounds of dry hay can be replaced with one 2-lb dry Hydration Hay® block.

If replacing all forage in a horse’s diet, be sure to feed at a minimum rate of 1.0 to 1.2% of body weight (10-12lbs/ 5-6 blocks for a 1,000 pound horse) with 2.0% of body weight preferred. Inadequate amounts of forage may lead to colic and other digestive disturbances.

    Hydration Hay® is rated 4.9 out of 5 by 12.
    Rated 4 out of 5 by from Suprised that they ate it! The horse I was going to transport is pretty picky and I wanted to make sure he stayed hydrated going across 3 states. I gave this in warm water and he liked it. Once it was cold I added a little apple juice to see if he would eat more and he did. I will keep these on hand for camping too!

    Rated 5 out of 5 by from A life saver Have old and retired horses, three with significant colic history. In this off and on horrible cold winter, none of them will drink adequately. They love this stuff when it is soaked in hot water and happily slurp it down. I add more water till it is almost hay soup. Have used other compressed hays, and this one is by far the best.

    Rated 5 out of 5 by from GREAT PRODUCT !!! We have a pony that is approximately 35 years old - she has very few teeth left. She has no problem eating her sweet feed, but cannot chew hay or even grass. She can "crop" grass but when she gets a mouth full, she has to spit it out because she cannot chew it. Purina's Hydration Hay solved our "roughage/forage" problem. THANK YOU PURINA for saving our pony !!!!!

    Rated 5 out of 5 by from My Horses Love This Product My horses love this stuff. Can't find it in my area so was very happy when I saw that Smart Pak carried it. Great for those ice cold days we sometimes get. I put this in a bucket with warm water and let it sit. Stir it up and give to my horses. This way I know they are getting some food and water on an icy day. They love it.
