I was out with my pup on a Sunday and we spent all day in the park playing. In the evening when he started to play with other puppies I noticed him get dull-eyed. A while later, he vomited! That’s when I blamed it off of one of his new friends but after getting checked by our vet it turns out that my puppy had become dehydrated from not drinking enough water due to me forgetting how much exercise they need for their little bodies because pups are still growing so fast and can’t tell us if something is wrong…I was really worried about him until I found these lines, which said “Puppies cannot control thirst or hunger like adults do.”. But then again, how can I know if my dog is dehydrated?

Whenever I notice any of these symptoms in my pup, I often try to make sure to give him some water and get him to the vet as soon as possible. There are many ways by which dehydration in dogs can be prevented by providing fresh water every day and avoiding strenuous exercise on hot days.

As a responsible dog owner, it is important to be on the lookout for signs that your dog may be dehydrated. Dogs can experience dehydration when they vomit or have diarrhea for a prolonged period. They also suffer from dehydration when they remain out in the sun for a long time without water. 

In this blog post, I will share my personal experience of preventing dehydration in dogs, why you should provide fresh water every day, and how avoiding strenuous exercise during hot days can be beneficial.

How Much Water Is Enough?

Based on rough estimates and my personal experience, a 20-pound dog should drink at least 1 ounce of water for every pound he weighs every day. That means dogs weighing less than 40 pounds, like most household pets, need about 4-5 cups of drinking water daily.

For larger breeds like the collie (65 pounds), you’ll want to offer them around 7 or 8 ounces per day, which is equivalent in size and weight between two large bottles or more than a full gallon jug on average, depending on their needs.

Although it may seem overwhelming to keep up with these high demands, your pup will remain safe if you keep any eye out for these needs. Generally, I monitor water needs by marking the drinker how high I filled them first and how much the water level dropped in 24 hours.

How to keep your dog hydrated?

As most of us know, dehydration is a big problem for our canine friends. But as difficult and distressing as it can be to treat the condition, preventing this serious health problem completely is much easier said than done! There are three simple things you should do to help your puppy stay hydrated:

1- Fresh Clean water must be available all the time 

There is no need to mention the fact that I always make sure my dog ​​has clean, fresh water available at all times. Especially when I go out for a longer period of shopping, and my dog ​​is unattended, I usually take a bowl or two of water and fill them completely. However, an automatic waterer is a much better option than other things.

Another problem I have found in the last few years is that many dogs do not drink standing water. For the dog, this type of stagnant water is a foreign substance and has been considered toxic by him in past experiences. This phenomenon is not exclusive to canines either; it is also quite common among other animals. If you have such a dog, give him moving water to drink; there are many pet water fountains available for this purpose.

2- Don’t take the dog out in the high temperature

One of the most important things I take care of is that I never take my Fido out in high temperatures because of the risk of dehydration. If there is an emergency and I have to take my puppy out to do his business, I usually try to keep him in the shade.  

 You may have heard that some dog breeds are more resistant to high temperatures, but the truth is that no dog breed can stay in high temperatures for long. Another option I’ve heard of is wearing a cooling vest. It will give dogs ​​a shield from the hot weather.

3- Always keep the water bottle along when traveling anywhere

When the summer season arrives, it is important to remember that our puppy also needs to drink water more frequently. Being outdoors for long periods can cause dehydration. Bringing water and food is an easy way to keep both ourselves and Fido, our dog, hydrated throughout the day. I always try to keep my Botup pet water bottle along with me for my dog. It is a perfect travel tool as it contains food and water container. 

Even if the place is close to home, I always have something in case an emergency arises or when my pet gets tired on the way back due to heat exhaustion or dehydration.

How does dehydration occur in dogs?

Whenever my dog ​​plays with his friends in the backyard, I keep an eye on him. However, it is natural for them to do all these activities such as panting, heavy breathing, etc. But this can lead to losing fluids from their body. And when they eat and drink, lost water is replaced!

The problem starts if my puppy does not take any fluid for the whole day, which means dehydration is about to start. When dehydration begins, it will lead to the reduction of fluid from the body, and as a result, the flow of blood to certain organs and tissues will also decrease.

Electrolytes are important for all kinds of living beings. They help in the digestion of food, keeping muscles working properly and nerves in check! If a dog is dehydrated, an electrolyte imbalance will also occur.

Common Symptoms of dehydration

By know you should be asking yourself: “is my dog dehydrated? How can I know?”. Well, if your pup suffers from dehydration, the most common signs that may appear: 

  • Less elastic skin
  • Diarrhea with or without vomiting
  • Loss of appetite
  • Fatigue
  • Less energy
  • Panting
  • Dry-looking eyes
  • Dry and moist gums
  • Dry nose
  • Thick saliva

How long can a pup live without water?

What I have heard from my vet is that a puppy can live without water for almost three days or 72 hours; I was shocked. But that does not mean that he will not show any signs in that time. The dehydration symptom will begin to appear after the first 24 hours. As time goes on, the puppies will become dehydrated.


Dehydration is a serious condition in dogs and can be life-threatening if not treated quickly. So next time that you ask yourself: is my dog dehydrated or if you notice that your pet has been losing weight or is acting differently than usual, call your vet right away for advice on rehydrating him. To prevent this from happening again, make sure your dog always has access to fresh water when out of his crate or pen.
