Why Is My Dog Drinking Less Water in Winter?

Date Posted:23 June 2025 

Noticing your dog’s water bowl staying full in winter? You’re not alone. Many dogs naturally drink less during colder months, but that doesn’t mean they don’t need proper hydration. Here's why this happens, and how to keep your dog healthy and hydrated all winter long.

 

Why Dogs Drink Less in Winter

Dogs are less active in winter, they sweat less, and they’re not panting to cool down like they do in summer, so it’s normal for their thirst to decrease. But this can become a problem if they’re not getting the fluids they still need for proper digestion, circulation and temperature regulation.

 

Signs Your Dog Might Be Slightly Dehydrated

  • Dry gums or nose
  • Sunken eyes
  • Lethargy or lack of interest in food
  • Skin doesn't spring back when pinched

Even mild dehydration can lead to bigger health issues, especially in older dogs or those with kidney issues.

 

How to Encourage Your Dog to Drink More in Winter

 

1. Warm Up Their Water Slightly

Room-temperature or slightly warmed water is more appealing than ice-cold water straight from the tap. Avoid boiling or hot water, just lukewarm is enough.

 

2. Add Bone Broth or Hydration Additives

Flavoured broths or liquid supplements make water irresistible and add nutrients. Look for dog-safe hydration products without added salt or onion.

3. Use a Pet Water Fountain

Some dogs love running water! A pet drinking fountain can stimulate interest and encourage more sipping throughout the day.

4. Offer Wet Food or Rehydrated Meals

Switching from dry kibble to wet food or adding water to their meals can sneak in extra fluids. Try mixing in a spoonful of warm water with their regular food.

5. Multiple Water Stations

Place bowls in different areas of the house so your dog has more opportunities to drink, especially if you have heating or fireplaces that can dry them out.

 

FAQ: Hydration in Dogs During Winter

How much water should my dog drink each day?
Dogs generally need 50–60ml of water per kg of body weight daily, but this can vary depending on activity level, age and diet.
Can dogs get dehydrated in cold weather?
Yes. Despite lower thirst, dogs still need adequate fluids. Dry indoor air and warm heaters can even increase dehydration risk.
Is wet food better for winter hydration?
Wet or rehydrated food naturally contains more moisture, which can help dogs who aren’t drinking enough from the bowl.
Should I be worried if my dog drinks less in June?
If your dog seems healthy otherwise, it's often normal. But monitor for signs of dehydration, and talk to your vet if you're unsure.
