Dogs really are man’s best friend. They are always happy to see you when you come home from work at the end of the night, and they always know how to make you feel loved.

They care about us, and we care for them. That is why it is so important that you feed your dog the right things, and that you give them the correct type of water.

There is much debate about whether, or not, it is safe to give your dog distilled water, and that is what we will be looking at in this guide. So, if you want to find out whether, or not, dogs can drink distilled water, keep on reading!

What Is Distilled Water?

First things first, let’s take a look at what distilled water is. Essentially, distilled water is a type of water that has been purified.

There are a number of different types of water out there that have been purified, and they all differ depending on the purification process. So, how is distilled water purified?

Distilled water is purified by being boiled into a vapor. Once boiled, the vapor is then condensed back into liquid form, in a different container.

The water in the new container is purified, whereas what remains in the original container is the impurities that naturally occur in water. Essentially, the water that is left is cleaner than the water that you started with.

This works because the impurities that are left do not boil below or anywhere near the boiling point of water. So, when boiled, the only thing that will vaporize is the water.

This means that any chemicals or minerals that were in the water to begin with, will no longer contaminate the water.

It is important to note that while they go through a similar process, boiled water and distilled water are not the same.

Boiled water is heated to boiling point to kill bacteria, but chemicals and minerals will not be removed. Whereas through distilling, all bacteria, chemicals and minerals will be removed, leaving only pure water.

So, now that we know what distilled water is, let’s take a look at whether, or not, it is suitable for dogs to drink. In short, yes, dogs can drink distilled water.

All harmful chemicals and bacteria are removed from distilled water, and essentially only clean water is left. Due to this, it is safe for your dog to drink distilled water.

However, it is not good for your dog to only drink distilled water. Distilled water is incredibly clean, but this isn’t always a good thing. Minerals are part of a healthy diet, and when water is distilled, these minerals are removed.

This can be very dangerous to dogs because it can damage their kidneys. Consuming minerals is important as it allows important electrolytes to enter the body. These electrolytes are very important for your kidney function.

So, yes, your dog can drink distilled water. However, you shouldn’t exclusively give your dog distilled water. Ironically, it isn’t that healthy for dogs to drink “clean” distilled water. Instead, regular water is much healthier for your pooch.

What Happens If A Dog Drinks Distilled Water?

What Happens If A Dog Drinks Distilled Water

So, you might be wondering what happens if your dog drinks distilled water. Well, as we have said, generally this depends on the amount of distilled water that you feed your dog.

In small amounts, distilled water isn’t harmful, primarily because there isn’t anything harmful in this water. However, it is the cleanliness of this water that can ultimately be dangerous for your pup.

Minerals aren’t necessarily a bad thing, and in dogs they are very important to maintain healthy levels of electrolytes.

The majority of minerals that enter your dog’s system will come from regular water, and dogs have become biologically dependent on these electrolytes.

When your dog doesn’t consume these minerals it can cause electrolytes to be lost through the kidneys, which can lead to low blood levels.

Dogs are a lot more hardy than humans, and because of this, their bodies have adapted to the minerals and chemicals that are often found in regular water.

While a small amount of distilled water will not harm your dog, if your dog only drinks distilled water, their body will not know what to do with it.

So, while you might be acting with good intentions when you give your dog distilled water, it is best to stick with regular water if you want your pooch to remain healthy.

What Type Of Water Should Dogs Drink?

Well, as we have said, the best water for dogs is regular water. Distilled water is still a fairly new concept, and because of this, our dogs bodies are not used to water that is this clean. On the odd occasion, distilled water is fine, but in the long term, it is harmful.

As well as potentially impacting the kidneys and blood, as we said earlier, distilled water can also cause your dog to become over hydrated as it can easily soak into your dog’s tissues.

This overhydration can also lead to water toxicity which can be very dangerous for your dog. Symptoms of this include irregular heartbeat, neurological changes, and, most commonly, fatigue. 

When it comes to water for dogs, you really cannot do better than regular water. Tap water might not be the best option for humans, but for dogs, there really is nothing better!

So next time you think about filling your dog’s bowl with a fresh bottle of distilled water out of the fridge, choose to run the tap instead.


In short, yes, dogs can drink distilled water. However, your dog shouldn’t exclusively drink distilled water because it does not contain any minerals.

Minerals are very important for maintaining electrolyte balance in your dog, and without the minerals that come from regular water, your pooch could become unwell!

So, while it might be tempting to treat your dog to distilled water, ensure that you only give them this as a treat!
