How Long Can A Dog Go Without Water?

Eating and drinking are beneficial for a dog’s health and wellbeing. However, water is more important than dog food in this situation. Dogs, in particular, can go longer without water than they can without food.

Dogs will usually go for two to three days without water.

It’s important to remember, though, that just because they could survive, it doesn’t mean it’s something they should go through.

When a dog is dehydrated, it affects all of its body’s functions. Their vital organs can malfunction if they do not have adequate access to new, clean water, resulting in death.

If your dog is sick and hasn’t been drinking water for longer than a day, you should get medical attention right away.

Apart from detecting and addressing the root cause, the veterinarian will most certainly keep them hydrated via IV fluids.

Since water makes up more than 70% of your dog’s body weight, he or she must drink water daily to stay hydrated. As a result, a 25-pound dog needs approximately 25 ounces of water. It seems to be a number, but keep in mind that it has to spread out over their whole day. Your dog’s everyday moisture requirements will also determine by food and treats.


What Is The Maximum Amount Of Time A Dog Can Go Without Water?

A small dog will go for at least 2-3 days without drinking water. However, the amount of time can determine by the following factors:

  • A stable dog can go through even more extended periods without drinking water. A sick dog, on the other hand, cannot go a day without water.
  • Dogs need extra water in the summer and can go for days without drinking in the winter.
  • Puppies are more likely than mature dogs to go without water for extended periods.

What Is The Best Way To Tell If Your Dog Is Getting Enough Water?

It’s not like you should keep an eye on him 24 hours a day. Extreme dehydration is usually linked to sickness or overheating, but a persistent condition of moderate dehydration may still be dangerous.

Here are a few fast tests to see if your dog is dehydrated:

1.   Gums

Your dog’s gums are an inherently moist region. To see if your dog’s gums are dry or tacky, lift its lips and brush them with your finger. If that’s the case, he will need a drink shortly. However, after a nap, it’s normal for gums and noses to be dry.

2.   Nose

The nose of your dog usually is wet. It is because dogs sometimes rub their paws. A dry nose isn’t always indicative of dehydration, although it may be associated with other symptoms. A dusty, cracked, or flaky dog nose may mean that it has been dehydrated for some time, even if only mildly.

3.   Pee

The colour of your dog’s urine may also be a sign of dehydration. Urine that is light yellow or pale is usually an indication of adequate hydration. Your dog is dehydrated if the yellow is deeper.

4.   Skin

The only way to tell if your dog is dehydrated is to look at the elasticity of his skin. Gently lift a pinch of their skin off their back. Release the skin and time how long it takes to return to its original position. If the skin lingers in place, like some little hair ponytail, the dog is in desperate need of water.

5.   Sunken Eyes

The dog’s eyes can get sunk deep due to a lack of water in both the body and the muscles that shield his pupils, and the only way to detect it is when the dog’s eyes get sunken suddenly.

6.   Looks Lethargic

Dehydration makes it harder to do most things; the dog’s muscles may have less oxygen pumping into them, resulting in less ability to sustain them, and they can become drained.

What Causes Dog Water Loss?

There are a lot of reasons why the dog is not drinking enough water. Let’s have a look at a few of them.

1.   Infection

A small dog’s regular water intake may disrupt by illness. If your dog has both oral and urinary tract infections, don’t force it to drink water. Such inflammatory disease can cause so much pain that a dog can go for long stretches of time without a water supply.

The below are some of the conditions that can cause a dog to go without drinking:

  • Periodontal disease
  • Dislocation
  • Tooth root abscess
  • Mouth cancer

2.   Tainted Water

Dogs are susceptible animals, capable of sensing tastes and odors that most humans are oblivious to. A dog can avoid water without displaying any signs of discomfort or pain.

If this happens, you can look for some anomalies in the water because it could be infected with soil or iron. To remain safe, dogs need constant access to transparent, clean drinking water.

3.   Ageing

Staying hydrated is difficult for an ageing dog. They won’t be as thirsty as more minor, more athletic puppies because they won’t get as much exercise. It means they would be less thirsty.

4.   Weather Condition

Another factor contributing to a dog’s inability to drink water for an extended period is the temperature.

The number of dogs that drink water to replace the fluids they’ve lost due to exposure to the sun. They will also control their body temperature by drinking water from time to time.

When the weather gets cold, the puppy may not retain as much liquid as he used to, so he does not lose as much fluid.


In the end, we want the most for our puppies. It’s critical to keep them hydrated, particularly when they’re young and vulnerable.

If you find several symptoms of thirst, such as dark urine or lethargy, consider one of the many solutions available to make your puppy drink enough water. If neither of these strategies operates, see your veterinarian as soon as possible.
