Summer horse care isn't just about keeping your horse cool. When temperatures rise and your horse starts sweating, water and electrolyte management become an important part of keeping them comfortable and healthy.
One of the simplest things that can get overlooked? Salt.
Here in the Southeast, our summers can be especially challenging because the combination of heat and humidity can make it difficult for horses to cool themselves efficiently. My horses live outside 24/7, so I pay close attention to how much they're drinking, how much they're sweating, and how I can encourage them to stay hydrated.
Over time, I've found that a few simple habits make summer management much easier.
Why Is Salt Important for Horses?
When horses sweat, they lose water along with electrolytes, including sodium and chloride. Salt provides sodium and chloride, and adequate sodium intake also helps maintain the normal thirst response. In other words, making sure your horse has adequate salt can help support normal drinking behavior.
That's one reason I don't overlook salt during the summer. My horses receive a ration balancer and grass pellets twice a day, and I add loose white salt to their feed. I also add water to their meals, which gives them another opportunity to consume moisture throughout the day.
Salt Blocks vs. Loose Salt
A lot of horse owners provide a salt block, and there's nothing wrong with having one available. However, I prefer loose salt because it allows me to know that my horses are actually consuming a measured amount rather than relying entirely on how much they choose to lick from a block.
Horses have relatively soft tongues compared with some other livestock, so they may not consume enough salt from a block to meet their needs, particularly when they're sweating heavily.
If you're looking for loose salt for your horse, basic white salt can be an inexpensive option. Always consider the salt already present in your horse's complete diet and talk with your veterinarian or an equine nutrition professional if you're unsure how much supplemental salt is appropriate.
Fresh Water Is Still #1
Salt is important, but it doesn't replace water. Your horse should always have access to clean, fresh water.
My horses can go through roughly 80 gallons of water every two to three days, although their consumption varies depending on the weather, pasture, activity level, and individual horse. During particularly hot weather, I make a point of paying attention to their water consumption.
If your horse suddenly isn't drinking normally, seems lethargic, has an unusually high or low water intake, or you're concerned about dehydration or heat stress, contact your veterinarian.
A Few Useful Watering Supplies
Having the right equipment can make managing water much easier, particularly if your horse lives outside.
Depending on your setup, useful items might include:
· Large water trough or buckets
· Trough cleaning brushes/Water-safe scrubbers
Add Water to Your Horse's Feed
Another simple way to increase the amount of moisture your horse consumes is by adding water to their feed. I add water to my horses' grass pellets and ration balancer. The pellets absorb the water, creating a wet feed that provides additional moisture with their meals.
You can also soak appropriate forage pellets or make a wet mash, depending on your horse's diet. This can be particularly useful if your horse is primarily eating dry hay rather than fresh pasture.
Of course, not every horse needs the same diet, so make sure anything you add fits into your horse's overall feeding program.
Helpful Feeding Supplies
If you're making soaked feeds or adding water to meals, a few simple supplies can make the process easier:
These are also good categories to keep an eye out for when shopping for pre-owned equestrian equipment. Feed buckets, tubs, and other durable horse-care items can often have plenty of life left in them even when they're no longer needed by their original owner.
Don't Forget About Fresh Grass
Fresh pasture can contribute moisture to your horse's diet because growing grass contains a significant amount of water.
That can be especially helpful during the summer when horses are consuming a lot of forage.
However, more grass isn't necessarily better for every horse.
Some horses need careful pasture management, particularly horses that are prone to weight gain or have other dietary considerations. Extremely short grass can also have different nutritional characteristics than mature, appropriately managed pasture.
For my horses, I prefer allowing the pasture to grow rather than keeping it grazed extremely short.
If your horse doesn't have access to suitable pasture, adding water to appropriate forage pellets can be another way to incorporate moisture into their diet.
What About Electrolytes?
You may also hear a lot about electrolyte supplements during the summer.
Electrolyte products can provide sodium, chloride, potassium, and other electrolytes, and they can be useful in certain situations—particularly for horses doing significant work or sweating heavily.
I personally don't routinely use a commercial electrolyte supplement with my horses. I focus on adequate salt, water, and moisture in their feed.
That doesn't mean every horse has the same requirements.
A competition horse working hard in extreme heat may have very different electrolyte needs than a horse standing in a pasture all day.
If you're unsure whether your horse needs an electrolyte supplement or how much they need, your veterinarian or an equine nutrition professional can help you determine what's appropriate.
Keep an Eye on Sweating
Sweating is a normal part of how horses cool themselves, but heavy sweating means they're losing both water and electrolytes.
You'll often notice sweat around the neck, chest, flank, and other areas of the body.
If your horse has been exercising or is sweating heavily simply from standing outside in extreme heat, pay attention to how they're behaving and recovering.
This is also where knowing your individual horse becomes important.
You learn what is normal for your horse—and recognizing when something is different can help you catch potential problems sooner.
Cooling Your Horse With Water
Hosing your horse can be another useful summer-care tool.
When cooling a hot horse, areas such as the chest and between the legs can be useful places to apply cool water, along with the rest of the body.
For routine post-summer-day cleanup, I personally prefer hosing my horses toward the end of the day rather than during the hottest part of the afternoon.
If you hose a horse down at 2 p.m. on a hot, humid day, they may simply go right back to sweating once they're exposed to the heat again.
Hosing toward the end of the day can allow you to remove sweat and help them cool down as the temperatures begin to drop.
Summer Grooming & Cooling Essentials
A few items I like to have available during hot weather include:
· Fly spray and fly-control supplies
· Towels or drying cloths
These are also categories where consignment can be especially useful. You don't necessarily need to purchase every piece of horse equipment brand new.
A good-quality used sweat scraper, grooming tool, bucket, or other durable piece of equipment can still do its job perfectly well.
What I Do for My Horses
Because my horses live outside 24/7, my summer management looks a little different from someone whose horse spends the hottest part of the day in a stall with a fan.
My basic routine is:
· Fresh water: They always have access to plenty of clean water.
· Salt: I provide loose salt in their meals.
· Water in their feed: I add water to their feed to increase moisture intake.
· Pasture: They have access to managed pasture, which provides additional moisture through fresh grass.
· Monitoring: I keep an eye on their drinking, sweating, body condition, and overall behavior.
These simple things have worked well for my horses, but every horse is different.
Building Your Summer Horse-Care Kit
You don't need to spend a fortune to put together a useful summer horse-care setup.
Start with the basics:
Hydration
· Large water trough or buckets
· Clean water source
Cooling
Feeding
Turnout
· Fly-control supplies (Fly Spray, etc)
· Appropriate fly protection (Fly Sheets, Masks, Boots)
Some of these items are inexpensive enough to buy new, while others are great candidates for quality used or consignment equipment.
That's one of the things I love about buying and selling pre-owned equestrian gear: horses require a lot of equipment, and not everything needs to be purchased brand new.
Shop Smart: New Doesn't Always Mean Better
If you're a new horse owner, it can be overwhelming to look at everything you think you need.
You don't necessarily need the fanciest bucket, the most expensive grooming kit, or every piece of equipment marketed to horse owners.
For many everyday items, function matters more than whether something came in a brand-new package.
That's where consignment can be a great option.
You can find quality pre-owned equestrian equipment at a lower price, while giving useful gear another life with another horse owner.
And when something needs to be purchased new—especially consumable products or items where you want a specific size or feature—Amazon can be a convenient option.
My goal is to help you find the right equipment for the job, whether that means buying something new or finding a quality used piece of tack or horse equipment.
When Should You Call Your Veterinarian?
Summer hydration isn't something to guess about when your horse isn't acting normally.
If you're concerned that your horse isn't drinking enough, is sweating excessively, isn't recovering normally after exercise, appears weak or lethargic, or you're seeing signs of possible dehydration or heat stress, contact your veterinarian.
Your veterinarian knows your horse's history and can help you determine what is appropriate for that individual animal.
Final Thoughts
Summer horse care doesn't have to be complicated.
For me, it comes down to a few basics:
Water. Salt. Moisture. Shade or appropriate cooling. And paying attention to your horse.
Making sure your horse has adequate salt can help support normal thirst and hydration, while adding water to feed and providing access to suitable fresh pasture can provide additional sources of moisture.
And don't forget the practical equipment that makes all of this easier—from water buckets and feed tubs to sweat scrapers and grooming supplies.
Whether you're shopping for something new or looking for a quality piece of pre-owned equestrian equipment, the goal is the same:
