Water is vital for keeping our furry friends hydrated, and their temperature controlled. But how much should they be drinking? It’s important to strike the right balance for your pooch.  

How much water should a dog drink a day?

Your dog should always have access to water. But the amount of water they should drink daily depends on their:  

  • age
  • size
  • activity level
  • diet
  • medical conditions and treatments.

Speak to your vet for specific advice for your dog, or if you notice a change in their drinking habits. Seek urgent veterinary care if you think your dog could be overheating, or showing signs of heat stroke.  

If you notice your pup drinking more in situations they’re unsure about, it could be their way of taking a break from things. Mention this to your vet if you notice your dog showing signs of anxiety or stress

Why do dogs stop drinking water?

If your furball is turning their whiskers up to water, or has reduced their water intake, it could be down to:

  • illness
  • mouth or throat issues
  • changes in their exercise levels
  • weather
  • changes in the water itself
  • anxiety
  • a disliking for certain water bowls.  

Some dogs may become worried around their water bowls. It could be that the sound of their collar hitting the bowl frightens them. Or there might not be enough water, particularly if they’re having to share.  

Seek advice from your vet if you’re worried about your dog’s drinking habits.  

How to get your dog to drink water

You should never force your dog to drink water. But some things that might encourage your pooch to drink a good amount include:  

  • keeping their water fresh, and their bowl clean
  • leaving water in different locations, using different bowls
  • using a non-slip mat or surface for their bowl  
  • making sure their bowl is the right size and height  
  • using a slightly elevated water stand for older or arthritic dogs
  • leaving them to it or staying nearby: whichever makes them feel relaxed.

If your dog still won’t drink their water, or you don’t think they’re drinking enough, speak to your vet. They’ll be able to offer more advice.  

Does wet food hydrate dogs?

This all depends on what the food is. Different foods have varying water content.

You may notice a change in drinking habits when your dog’s diet is changed. Particularly if changed from a wet to dry diet, or visa-versa. Your vet may be able to provide more advice on how hydrating your dog’s food is and whether there is any cause for concern.

What are the signs of dehydration in dogs?

Like any owner, you want to know that your hound is hydrated. It can be difficult to recognise dehydration in dogs, but some possible clues include:

  • dry gums
  • loss of skin elasticity
  • sunken eyes
  • low energy
  • weakness
  • panting
  • vomiting
  • changes in breathing

Make sure your pooch always has access to fresh and clean water, but speak to your vet if you’re worried they’re dehydrated or show any of these signs.  

Will a dehydrated dog still urinate?

A dehydrated pup won’t necessarily urinate less. Some conditions can even make a dog urinate more, despite being dehydrated. You should speak to your vet if your pooch is peeing more or less than usual, or if you are concerned that they’re dehydrated.

Can you syringe water to a dog?

No, unless recommended by your vet for a specific condition.  

If your vet has suggested this, make sure to follow their instructions and use as little force as possible. Using force only makes our furry friends more frightened and stressed. Water could even go down the wrong way and into the lungs.  

How long can a dog go without drinking water?

The answer to this varies from dog to dog and is influenced by external factors such as temperature. Speak to your vet to find out about guidance specific to your individual pooch.

Some mischievous mutts may tip over their water bowl when left alone. You can call our free Behaviour Support Line for expert guidance on how to navigate this.  You can also find anti-tip bowls at most pet retailers.  

Top tip: set up multiple bowls of water around the house, so that your dog can still access the wet stuff after a mischievous moment.

The bottom line

A hydrated hound is a happy hound. Your dog should always have fresh and clean water available to them, but never force them to drink it.  

Speak to your vet if you’re concerned about your pooch’s water habits. They’ll put your mind at ease or offer more guidance.
