If your dog won’t drink water, or is drinking less than usual, it’s natural to worry. Water is vital for your dog’s health and wellbeing.
Here’s why dogs sometimes drink less, how to spot dehydration, and simple ways to help your dog stay hydrated.

How much water should a dog drink a day
As a general rule, dogs need about 40–60ml of water per kilogram of body weight per day.
For example:
- Small dog (6kg): about 300ml a day
- Medium dog (13kg): about 650ml a day
- Large dog (30kg): about 1,500ml a day
- Giant dog (60kg): about 3,000ml a day
Dogs eating raw or wet food (like our RAW POWER or MIGHTY MINCE) naturally get more moisture from their meals.
Dogs eating dry kibble need to drink more.
How to tell if a dog is dehydrated
Watch for these signs:
- Lethargy
- Dry, sunken eyes
- Sticky gums
- Thick saliva
- Excessive panting
- Loss of skin elasticity
Skin test: Gently lift the skin at the back of your dog’s neck. In a hydrated dog, it should spring back quickly. If it stays raised or slow to return, your dog may be dehydrated.
Gum test: Press a finger on your dog’s gums — the spot should briefly turn white, then pink again. If the pink is slow to return, this may signal dehydration.
If you’re concerned, contact your vet and encourage your dog to drink small amounts of fresh water.
How do I get my dog to drink more water
Here are simple ways to help:
-
Fresh water: Change water often. Dogs like clean, cool water.
-
Filtered water: Some dogs prefer filtered or bottled water, especially if your tap water tastes different.
-
Multiple bowls: Place bowls in different rooms and on each level of your home.
-
Accessibility: For older or stiff dogs, consider a raised bowl.
-
Clean bowls: Wash water bowls regularly to avoid slime or bacteria.
-
Wet food: Add water to meals to boost hydration.
-
Out and about: Always carry a travel bowl or bottle on walks.
-
Pet fountain: Some dogs love running water — a pet fountain can encourage drinking.
Why isn't my dog drinking water
Possible reasons include:
-
Illness: Anything from a mild stomach upset to kidney disease can affect thirst.
-
Mouth or throat pain: Dental problems, sore throat or jaw injury may make drinking uncomfortable.
-
Weather: It’s normal to see reduced water intake in cooler weather or during less active periods.
-
Water source: Your dog may dislike the taste or smell of unfamiliar water.
-
Anxiety: Stress can lower appetite for both food and water.
-
Negative association: A bad experience near the water bowl may cause reluctance.
-
Fussiness: Some dogs are simply more particular!
When to seek help: If your dog stops drinking completely, or drinks significantly more or less than usual, always check with your vet.
Why is my older dog not drinking water
Older dogs may drink less due to:
- Lower activity levels
- Mobility issues (difficulty reaching bowls)
- Health conditions
- Cognitive changes (forgetfulness)
It’s wise to mention any change in drinking habits to your vet, especially in older dogs.
Final thought
Staying hydrated keeps your dog happy and healthy. A few small changes can encourage them to drink well throughout the day.
And after a refreshing drink, why not treat them to a nourishing RAW POWER meal or some tasty MIGHTY MINCE?
Here’s to happy, healthy, hydrated dogs!
