Despite many wanting to scoff at everything in sight, many pooches simply aren’t as keen when it comes to drinking water. Hydration is crucial when it comes to a dog’s health, as it’s essential to all their vital processes. In the summer months, this becomes doubly important, as dogs lose a lot of moisture in warm weather. Plus, they find it hard to regulate their body temperature without water to help cool themselves down.

Sometimes, it might seem impossible to get your dog to drink enough, and the last thing you want is a parched pooch! So to keep your dog happily hydrated and well-functioning, read on for some smart tips and tricks to encourage your dog to drink more water.

 

Reasons why a dog won’t drink 

There could be a number of reasons why your dog won’t drink enough water.

 

  • Illness is one of the most common causes, especially issues like infections, nausea, or the sick feeling that comes from dental issues. If they have a UTI, for instance, they might not drink because peeing is painful.

  • Pain or injury can make it uncomfortable to move toward the bowl or even lower their head to drink; this can also happen after surgery.

  • Stress and anxiety caused by separation, a noisy environment or recent changes at home (a house move, new baby or pet) can also disrupt your dog’s normal drinking habits.

  • Older dogs may drink a lot less than they used to in their younger years, which is worth keeping an eye on, even though it’s normal.

  • Finally, dogs can be fussy! They might not like the positioning of their drinking station, an unclean or smelly bowl, or if the water is lukewarm or old.

 

 

Why is hydration important for dogs?

Drinking water supports every vital function in your dog’s body, helping deliver a variety of functions, including:

 

  • Lubricating vital organs

  • Encouraging digestion

  • Supporting circulation

  • Boosting energy and vitality overall

 

Dogs also have extra struggles in the warmer months, because they can only cool off through their tongues (by panting) and their paw pads. This means they need extra help regulating their body temperature, and drinking enough water is super important in keeping them cool and comfortable.

 

How much should my dog drink?

Your dog should be getting an adequate amount of water per day, depending on their age, size and breed. 

  • A small dog may only need a quarter litre of water per day (around 250-300ml).

  • A mid-sized dog, around half a litre to a litre a day (500-1000ml).

  • A large dog, anything from 1.5 to 2 litres (1500-2000ml). 

 

 

Signs of dehydration in dogs

Severe signs of dehydration will require an emergency visit to the vet.

Look out for the following indicators that your dog isn’t getting enough water and could be suffering from dehydration.

 

  • Dry or tacky gums rather than moist, slick to the touch.

  • Sticky saliva, as if there is little moisture in their mouth.

  • Dry nose. Dogs’ noses aren’t always wet, but a dry nose can be a sign of dehydration.

  • Lethargy or low energy. Dogs who haven’t had water in a while will seem tired and sluggish throughout the day.

  • Sunken eyes that don’t have their usual brightness.

  • Panting more than usual, and not just because it’s hot. Panting without a clear reason can point to dehydration.

  • Loss of skin elasticity, when the skin doesn’t spring back when you lightly pinch it.

 

How long can a dog go without drinking water?

Your dog needs a drink every single day.

But for those that eat wet food, the amount of water they drink may seem less as the wet food provides the hydration they need. 

If they go 24 hours without water, they will start to show signs of dehydration, and the average dog will only survive up to three days without a drink. 

If you’re worried your pooch might not have drank all day, look out for signs they may be dehydrated and offer them fresh water to glug. If they refuse, do not force them to drink - there are more strategic ways! 

 

How do you motivate your dog to drink water?

If your dog is refusing to drink, do not force them to.

It’s very important that they drink the water on their own, unless administered by a vet.

When they do drink on their own, offer them praise and a healthy dog treat so they’re encouraged to do it again.

Try mixing your dog’s food with some water or dog-safe bone broth so they get extra hydration while eating. You could also offer them water from different bowls and bottles, or try any of the following tips and tricks to get your dog to drink!

 

 

How to get your dog to drink water: Tips & tricks

Dogs can be fussy when it comes to drinking! Get ahead of their hydration by trying some of these nifty dog-drinking tricks.

 

  • Always refresh their water. You wouldn’t want to drink old, dusty water - nor does your dog! So make sure their water is always fresh. Each morning, empty their water bowls and give them a wash before refilling with fresh, cool or cold water.


  • Offer ice cubes or ice lollies. Especially in the warmer weather, try some frozen treats, such as ice cubes with a blueberry or chunk of apple inside. You could also freeze some dog-safe broth or unsweetened coconut milk in an ice-lolly mould, and offer it to them to lick (just don’t let go of the stick).


  • Flavour their water. Plain water can be dull for your pooch, so make it more exciting with dog-safe foods like berries, watermelon, tuna water or bone broth. They should always have a source of plain water nearby, but it can be nice for them to have alternatives.


  • Make it easy for them to drink. Water should be placed at various places in the house, and be easy for them to reach. If they’re outside a lot, place some fresh water in the garden. Be sure the bowls are big and full enough, and placed at a suitable height so they don’t have to stretch or bend too low. Plus, be sure to monitor and constantly refresh water bowls that are kept outside to avoid any bacterial build-up or the ingestion of nasties.


  • Try all kinds of receptacles. Dogs like to drink from bowls, bottles, your hand, tupperware, jugs and more. Try placing an unusual container filled with water somewhere that your dog can reach - the novelty alone might encourage them to drink. Even a well-placed pet water bottle with a straw (one that usually feeds rabbits and hamsters) can be intriguing to a fussy dog.


  • Integrate drinking with playtime. Water doesn’t have to come from a bowl - dogs love to drink and snap at water from fountains, water sprinklers, hose pipes and paddling pools in the summer. If you can disguise drinking as playtime with water, your dog won’t even notice they’re hydrating themselves.


  • Hydrating treats. There are so many foods with high moisture content that can contribute to your dog’s hydration. Watermelon chunks, cucumber, strawberries, red bell pepper, mango, celery or dog-friendly bone broth or ice lollies (as mentioned above) can all help towards your dog’s water levels.

 

  • Spoon-feed them water. Your pooch will love the one-to-one attention you give them by feeding them water directly with a spoon. You could also try a ladle or a pet-friendly syringe, or just offer water in your cupped hands.


  • Give lots of praise. Your pooch should get the message loud and clear that it’s a good thing when they drink water, so make sure to give praise and affection, or even slip them a healthy treat each time they go for a sip. This is especially important if they don’t drink as often as they should.


 

  • Add water to food. It’s an obvious one, but mixing up your dog’s usual food with some warm water, or dog-friendly bone broth, can make it more appetising, and add to their hydration. Dry kibble, especially, can become more appealing when softened with a splash of water in your dog’s bowl.


  • Bring a drink on walks. Your dog is most likely to get thirsty when exercising, so be sure to always bring water with you on a dog walk for on-the-go drinks. You can feed your pooch water from a doggy water bottle or a collapsible water bowl. 

Should I be worried that my dog isn’t drinking enough?

If your pooch doesn’t seem interested in drinking, it could just be a bad habit that needs gentle encouragement to become more regular. 

If your dog still won’t drink after all of the tips listed above, however, you should definitely book an appointment with your vet to check that there aren’t any underlying causes. 

 

FAQs

Why won't my dog drink water from their bowl?

Sometimes, dogs are simply uninterested in drinking water from the expected place. Be sure the water is fresh and easy for them to reach, and that their bowls are clean. You could also try hydrating your dog in other ways. This includes mixing water with their food, leaving water in different places, in varying receptacles, and offering hydrating treats such as watermelon and cucumber.

What can I put in my dog's water to encourage drinking?

You can flavour your dog’s water to make it more exciting for them by adding bits of dog-safe fruit (such as blueberries), some unsweetened coconut water, the spring water that comes with tuna, or some tasty dog-friendly bone broth. You could also try popping in some ice cubes or frozen treats into your dog’s water.

Does kibble make dogs more thirsty?

Kibble can make a dog more thirsty because it doesn’t contain the moisture content of wet food, which is more hydrating. As it’s very dry, you want to be sure you’re offering your pooch water sources while they’re eating. Have a few water bowls or receptacles around the house, offer them hydrating treats such as cucumber, strawberries or melon, and try mixing their dry food with a splash of warm water or dog-friendly bone broth from time to time.
