How Much Water Should a Dog Drink?

So How Much Water Should a Dog Drink?

Freshwater should be available at all times for your dog’s health and comfort. Water is extremely crucial to the dog, accounting for roughly 70% of its weight.

A dog, like a man, can go without food for a remarkable amount of time, but if he is deprived of water, he cannot survive in a hot, dry environment for more than a few days, if not hours.

The amount of water used by a dog varies depending on the weather, his activity, and the composition of his meals.

Heat and activity quickly dehydrate him. Inside an auto or any enclosed place, he becomes extremely thirsty.

Sometimes, anxiety will make your dog thirsty and this is a concern especially if your dog is left alone for extended periods.

Excessive thirst for no apparent reason should be reported to your veterinarian, as it could be a sign of diabetes or kidney disease.

At home, he should have a clean, full water bowl next to his feeding dish, another in his play area, and potentially a third that is accessible at night.

Is it OK to give dogs tap water?

Tap water is a great option for pets. In most cases, tap water can be safely given to your pet and it’s cost-effective too! As a rule of thumb, if you drink tap water in your country and it’s fine for you then it will be fine for your dog.

The problem is harder to solve while you are not at home.

A thirsty dog is drawn to water in the gutter, stagnant pools, and rain puddles.

Clean rainwater is ideal, but it is difficult to come by.

Most standing water is contaminated by caustic chemicals used to melt snow on streets and sidewalks, as well as weed-killers and insecticides used on lawns and golf courses, and should be avoided.

Train your dog to just drink from his own bowl or from what you provide him.

Is bottled water safe for dogs?

Bottled Water for Dogs?

Owners of dogs should look for certified products, like those that use the same membrane in all these other things. That way you know your pup isn’t getting any flavor or chemicals added to their water!

Offer Plenty Of Water Opportunities When Travelling.

Keep a water-filled plastic container on hand or in your car, especially if you plan on doing a lot of walking or running in hot weather.

If not water then what?

Apart from water, milk is the only drink that dogs find appealing and agreeable (although it may cause loose stools).

They are rarely lured by other drinks and, in particular, loathe fizzy beverages.

Milk is another fantastic source of protein, however, it should not be used in place of meat.

Any flavored drink should be avoided because it just irritates the kidneys, resulting in frequent urine and dehydration.

That said, if your dog has developed bad breath then adding a drop of specially medicated mouthwash (for dogs) can often improve the flavor for them and their breath!


This great video explains a lot about why it’s important for us as responsible dog owners to keep a check on our dog’s daily fluid intake.

We have taken the trouble of transcribing this video as it explains a lot more about the health-related aspects of water for your dog and also if there are indicators we should be looking for.

Having information on how much water your dog is drinking can really help us when it comes time to figure out what’s wrong with them if they’re sick.

In this video, I’ll show you how you can go about measuring how much water your dog is drinking.

I’m Matt young from companion animal vets, and you’re watching us live in our family pet care video series. It’s your guide to the latest information and best practices to help you care for your family pet.

Many chronic diseases that affect dogs lead to an increase in thirst which means that they would drink a lot of water.

Knowing how much water they are actually drinking can greatly improve our ability to diagnose the causes and can also be used to monitor treatment.

There is a long list of diseases that cause an increase in drinking in your dog.

This includes kidney disease, diabetes, Cushing’s disease, which is another hormonal issue, psychogenic polydipsia.

This is a strange condition where the dog develops a psychological condition where they compulsively drink too much water and many others, measuring how much water your dog drinks is important.

In the course of coming out with a diagnosis of these conditions, it is always important to work out whether they are truly drinking too much water.

Detecting an increasing first can help us to detect these diseases before they become really sick.

In some, the diseases like diabetes, can be used as an excellent indicator of how effective our treatment is.

The amount of water a dog drinks each day can be altered by many factors, which include the amount of exercise they have done, the type of food they are drinking, and the weather.

For example, if it is very hot and dry, they’ll drink more, it can be difficult to accurately determine they may be drinking from multiple water bowls, there may be multiple animals drinking from the one bowl or they may be getting water from sources you can’t control such as ponds and pools in order to accurately work out if it’s necessary to control as many of these variables as possible.

What we ultimately want to achieve is a measure of how much water your dog is consuming in a 24 hour period.

Here’s the way you should do it.

Limit your dog’s access to water so they are confined to an area that only has access to one single water source.
Ultimately, make sure there is only one dog you are measuring in the area with access to that water bowl and to the water bowl, and mark a line on the inside surface with a permanent marker and then fill the bowl to the line with water.

Whenever you top up the bowl. Use a measuring jug to determine how much water is missing.

Do this by refilling to the line, jot down the amount in each state and continue measuring for three days. We’ll take the average over the last three days.

This helps us to eliminate variability due to things like changing temperatures. If you have more than one dog drinking from the bowl, and it’s not possible at all to separate them for the test.

Here is a bit of a trick, still measure the water intake in the same way but make the assumption that the other dog or dogs are consuming a normal amount of water.

For a typical dog that is just lazing around normal water, drinking is determined by this formula, which can be also found in the video description.

In order to do it accurately, it is necessary to control as many variables as possible.

If your dog is drinking more than 90 MLS per kilo per day, that is not normal.

And it’s time for a visit to the vets to work out why the formulary is 140 times their body weight to the power of 0.75 and this gives us an answer in MLS per day.

In summary, measuring the amount of water your dog is drinking can help find disease and to use it to monitor treatment.

And as we always advocate, if you notice any changes or something simply doesn’t feel right with your dog’s drinking habits, then get it checked out with your vet.
