How Long Can a Dog Go Without Water?

Dogs can go for days without water. They get needed fluids by drinking their mother’s milk while they are nursing.

The average adult dog will drink about 10-20% more water than an adult human. It is not just the heat that makes dogs want to drink more, it is also because their body temperature is usually higher than ours and they don’t sweat as we do.

Each year, thousands of dogs die in the United States because they are left in hot cars without any water.

All dogs need to drink at least one ounce of freshwater per 10 pounds of body weight every day. A dog weighing 50 pounds would need five ounces of water every day.

Dogs cannot survive more than a few days without water, but don’t worry – it is not hard to make sure your dog stays hydrated!

How Much Water Should Dogs Drink?

A common question of people who own dogs is how much water should they drink. When it comes to hydration, there is really no universal answer to this question.

Some people believe that dogs do not need to drink water and instead rely on their food and the moisture in the air to stay hydrated; others say that a dog needs to drink enough water at least once per day, but not too often.

It is important to know how much water a dog should drink because not drinking enough can lead to different health problems.

Some dogs drink more, some less according to their needs, but the average amount of water a dog should drink per day is about 150-200 ml per kilogram of body weight which equals 10 cups of water for a 50-pound dog.

Dogs are just as susceptible to dehydration as humans are. If your dog is urinating less than usual, has a dry mouth, is panting excessively, or has other signs of dehydration, water consumption should be increased.

Dogs require more water than other animals because they release heat through their tongue and nose rather than through the other areas as humans do.

Warning Signs That Your Dog is Dehydrated

It’s important to know how to tell if your dog is dehydrated. Dehydration can be a serious condition and can even be life-threatening if left untreated.

Signs of dehydration include dry nose and mouth, decreased skin elasticity, sunken eyes, depression or lethargy, and normal/increased heart rate.

If you notice any of these indicators in your pup, it’s best to consult with a veterinarian before anything else.

Dogs should drink a minimum of 8 oz. of water per pound of body weight or 20 ounces for a 10 lb. dog.

Owners can check their dog’s hydration status by feeling the pads of his paws, asking him to “sit” and looking at his eyes.

A sign that your dog needs water is if he lists to one side when he sits or if his eyes are sunken and dry.

How Long Does Dehydration Last in Dogs?

It is important to know the answer to this question if you find yourself in a situation where your dog has not had any water for 12 hours.

Studies have shown that the effects of dehydration on dogs start showing after about 12 hours without water, with serious effects of dehydration starting after 16 hours.

The first signs of serious dehydration are manifested as tiredness and lethargy, which can worsen over time without proper medical attention.

Why Won’t My Dog Drink Water?

Your dog may be unwilling to drink water for a number of reasons. Does your dog refuse to drink water? Have you noticed that your pet’s weight is steadily decreasing?

Have they been vomiting or had diarrhea recently? If the answer to all of these questions is yes, it’s likely that your pet has an electrolyte imbalance, which can be life-threatening if not treated immediately.

If this is the case, contact your veterinarian as soon as possible.

How Do I Get My Dog to Start Drinking Water Again?

Some dogs will stop drinking water if they are not getting enough fluids. They may also start to drink dirt and other unwanted items in order to get the moisture they need.

Pets that tend to be picky about what they will eat may also refuse to drink water, which can cause dehydration and weight loss.

Even though your dog is not always drinking as much water as he or she should, there are some steps that can be taken at home to help get their water intake back up.

A first step would be to provide clean, fresh water all day long.

The water bowl needs to be placed in a spot where it’s easy for the dog to access. Another idea is to use ice cubes or frozen juice popsicles to make the water more appealing.


In conclusion, the best thing to do is to consult with your veterinarian. However, if you are experiencing any of the above symptoms it would be best to contact them as soon as possible.

If you’re noticing that your dog has been foregoing water and their stool and urine is getting darker in color, take them to the vet fast!
