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.

Hydration Hay is rated 4.7 out of 5 by 48.
Rated 5 out of 5 by from Horse Aproved Hydration Snack I bought this for my senior gelding to keep him hydrated during the colder months. My equine nutritionist had recommended it and uses it for her personal horses in snowy conditions, so I figured I'd give it a try. My horse can be a picky eater, however he absolutely loves this stuff! I feed half a brick/block in warm water daily and he is eager to slurp up the very last drop. The hay is finely chopped so it absorbs fast. You can also break it apart easily with your hands while its dry to help it soak faster. We add a pinch of salt to it.

Rated 5 out of 5 by from Great product. I actually bought this last spring for a sick mini and I thought I could use when at a clinic or traveling to encourage eating and drinking. Mini was sick, and wouldn’t eat it and the traveling horse was so picky, she wouldn’t eat it either. Now to current time, it’s been cold and I have some powdered supplements for an old pony. I soaked some to try and all three horses loved it. Like obnoxiously love it. I cold temperatures it it ensures they get their electrolytes and other supplements. I just wet enough over night for the next feeding. Then start the next for evening. It stays inside so it doesn’t freeze.

Rated 5 out of 5 by from My ancient picky burros love it! I bought it because my vet recommended it and we are having a hard time getting good hay in my area. I love it, the ancient burros love it and the mustang mare loves it. I crumble it first, so that it soaks easier and it’s a super way to add supplements that the burros would pick out of dry feed. The auto ship is a wonderful service.

Rated 1 out of 5 by from NOT FOR PICKY EATERS Wish I had never bought these, super disappointing. My horse doesn't eat it. Hell take like one bite and then stops. Waste of money.

Rated 5 out of 5 by from Great for a mid day snack I live in Arizona where summers get to 115 in my area. I like to give my horses a mid day snack with water mixed in so I know they are getting their fluids. I mix half a cube with some carrots and both my horses love it and clean it up.

Rated 5 out of 5 by from Less stress, less mess I purchased Hydration Hay for an upcoming move. I’m currently fighting dehydration at home with my senior guy and I’m worried about him staying hydrated over the three-day road trip. I figured feeding hydration hay would be my best option to keep him hydrated and reduce wasted hay going down the road.
