How Much Water Should A Horse Drink A Day

How Much Water Should A Horse Drink A Day

If you’re concerned about how much water your horses drink, you’re not alone. Water is a crucial part of your horse’s diet, and if it isn’t getting enough, it can suffer all kinds of health problems.

This article covers the amount of water horses need to stay healthy. It will answer questions like:

How much water should my horse drink?

Why does my horse refuse to drink?

What happens if my horse doesn’t get enough water?

By the time we’re done, you’ll know exactly how much H2O your horse needs! Let’s get started:

A 450-kg (1,000 lb.) horse requires at least 25 litres of clean water each day.

  • Clean, fresh water should always be available.
  • Water should never be hot or frozen.
  • Water quality must be checked regularly, and if the water is not clean, it must be changed immediately.
  • Stale water can cause digestive disturbances and colic in your horse.

How much water does your horse need to drink every day to stay healthy and how much do water requirements increase in hot conditions or when working?

Ensuring adequate water intake is important for the optimal health and well-being of all horses. Some horses are more susceptible to becoming dehydrated and have a higher need for water.

A typical, idle 500 kg horse requires at least 25 litres (6.6 US gallons) of water per day.

In hot weather, horses may require 55 litres (15 US gallons) per day and they may need anywhere from 40 – 70 litres (10 – 18 gallons) per day when exercising.

Even if you provide your horse with constant access to fresh clean water, horses will not always drink enough water to avoid dehydration.

In particular, water intake should be intentionally encouraged in exercising horses, lactating mares, horses with gastrointestinal issues, and during both hot and cold weather.

This article discusses why adequate water intake is important, factors that can affect water intake, how to assess dehydration, and how to encourage water consumption in horses.

Horses won’t drink if they do not like the taste or temperature.

Horses are notoriously picky eaters. They will not eat if the taste or temperature of the food is off. This can also apply to water, which they usually prefer warmer than humans do (taste preferences vary). If a horse does not like the temperature of his water, it’s likely that he will not drink enough and could become dehydrated. The same goes for when a horse does not like what has been put in his water as well; some horses have been known to refuse to drink from plastic buckets or containers due to the sound of them hitting against each other when being filled up with water.

Horses should drink between 8 and 10 gallons of water per day on average.

A horse’s water intake is affected by several factors, including their size, age and activity level, as well as the weather. The amount of water a horse should drink also depends on the type of feed being fed.

The average horse will drink between 8 and 10 gallons of water per day on average. However, this can easily be adjusted depending on the conditions and needs of your particular animal!

Horses that are sick or foaling can consume much more than eight gallons a day.

If you have a sick horse, they may be more likely to consume more than eight gallons of water a day. Foaling mares also need extra water because they lose a lot of fluids during the birthing process. If you notice your horse is drinking more than usual and/or refuses to drink from their water trough, it’s important to bring them in for vet care immediately.

If you offer your horse a salt block, you may need to add a little more water to their diet.

If you offer your horse a salt block, you may need to add a little more water to their diet. Salt blocks are a good source of minerals and some horses will be attracted to them because of the salt content. They can also be a good alternative to salt licks for horses that don’t like licking the ground or carrying around something heavy in their mouth.

If you use a salt block regularly and keep it well-watered, then this could help encourage your horse to drink more as well (and therefore get enough water). In fact, depending on how long it takes for your horse[…]

Young horses require about twice as much water as adult horses, and lactating mares need even more than that!

  • A horse’s water requirements depend on its age, weight and activity level. This means young horses require about twice as much water as adult horses and lactating mares need even more than that!
  • The weather can also affect how much a horse will drink. On hot days, they’ll need more water than on cool days to replenish lost fluids.
  • Similarly, different types of feed add more or less moisture to the diet compared to others. For example: grass-fed diets are usually lower in overall moisture content (because they contain less water), while grain-based feeds have higher levels of moisture depending on what type you buy (the higher quality ones have less).

Water is the most essential nutrient for your horse, and fresh, clean, cool water must always be available to him. Dehydration can lead to poor performance, lethargy, colic, kidney damage, collapse and even death. Unfortunately, there are people who intentionally withhold water at shows to quiet their horses. This is an extremely dangerous practice and never appropriate. In addition to harming the horse, withholding water can lead to yellow cards and fines if you are caught.

Water makes up about 70 percent of a horse’s total body weight, and maintaining this balance is essential. The average horse will drink 5 to 15 gallons per day or about 1 gallon per 100 pounds of body weight. Broodmares need even more—about 20 gallons per day to produce milk for their foals.

One of the most important factors determining water intake is dry matter intake, for instance, how much forage your horse is eating. Horses sweat up to 2 to 3 gallons per day, so how hard your horse works also has a significant effect and may triple the water requirements. Heat, humidity and health status also have an effect.


As you can see, there are many factors that go into calculating how much water a horse should drink each day. You may want to keep a log of your own horse’s consumption habits and compare them to the guidelines we have provided here so that you know whether or not they are getting enough fluids.
