It’s a common question, and unfortunately, there is no easy answer. Just like with people, the amount of time a dog can go without water depends on a number of factors, including their age, health, activity level, and climate.

Most healthy dogs require around 1oz of water per unit of body weight each day. For example, a 10-pound dog would need around ten ounces of water each day. Of course, this is only a starting point; some dogs may require more or less depending on their individual needs.

Now let’s take a closer look at the factors that can impact how long a dog can go without water.

Age: Puppies and senior dogs are more susceptible to dehydration than adult dogs, so they will need more frequent access to water.

Health: Dogs with health conditions that make it difficult to absorb or retain water (such as diabetes, kidney disease, or Cushing’s disease) will need more water than healthy dogs.

Activity level: Active dogs (especially those who exercise in hot weather) will need more water than sedentary dogs.

Climate: Dogs in hot climates will need more water than those in cooler climates, as they are at a greater risk for dehydration.

How Much Water Does a Dog Need Per Day?

A healthy dog should drink 1/2 to 1 oz of liquid per unit of body weight every day.

A 10-pound dog, for example, needs at least 5 ounces of water per day, whereas a 100-pound dog requires at least 100 ounces (or roughly 12 1/2 cups) each day.

Puppies and elderly dogs require more water than adult dogs, so keep that in mind while ensuring your pet is getting enough to drink.

How Much Water Should I Give My Dog If He’s Sick or Exercising?

  • If your dog is sick or exercising more than usual, he will need more water than normal.
  • A dog with diarrhea can lose a lot of body fluids and will need to drink more water to stay hydrated.
  • If your dog is vomiting, don’t let him drink too much at once or he could end up bringing it all back up again.
  • Give small amounts of water frequently until his stomach settles.
  • Dogs that are hiking, playing fetch, or otherwise working hard in hot weather will also need more water than usual to stay hydrated and avoid heat stroke.

When Should I Worry That My Dog Is Not Drinking Enough Water?

If you notice your dog is drinking less water than normal, it’s important to take action right away. Dehydration can cause serious health problems, so you’ll want to make sure your pet stays well-hydrated. A good way to check if your dog is dehydrated is to look at his gums. They should be moist and pink. If they are dry or tacky, it’s a sign he’s not getting enough fluids. Other signs of dehydration in dogs include sunken eyes, loss of energy, and dizziness. If you think your dog is dehydrated, take him to the vet right away. Dehydration can be life-threatening, so it’s best to err on the side of caution.

There are a few things you can do to encourage your dog to drink more water:

Add some flavor

Adding a little bit of chicken broth or low-sodium beef broth to your dog’s water bowl can make it more appealing to him.

Give him ice cubes

Most dogs love chewing on ice, and it’s a great way to get them to drink more water.

Make sure his bowl is clean: A dirty water bowl can be unappealing to your dog, so make sure to clean it regularly.

Add a water fountain

Dogs are attracted to running water, so adding a water fountain to his area could encourage them to drink more.

Invest in a doggy water bottle

If you’re on the go with your dog, bringing along a doggy water bottle is a great way to make sure he stays hydrated.

Final Thoughts

How long can a dog go without water? The answer to this question depends on a number of factors, including the dog’s size, age, and health. However, in general, a healthy dog can survive without water for about three days.

Of course, this is just a general guideline. If your dog is sick or elderly, he may not be able to last as long without water. And if the weather is hot, your dog will need more water to stay hydrated.

If you’re ever in doubt, it’s always best to err on the side of caution and give your dog extra water. After all, it’s better to be safe than sorry!
