During winter, many pet parents notice the same thing:
their dog or cat just isn’t drinking as much water.
It’s easy to assume that hydration matters less when it’s cold — but for pets, the opposite is often true. Winter brings subtle changes that can reduce water intake while increasing the risk of dehydration.
Here’s why cats and dogs drink less in winter, what that can affect, and how to help them stay properly hydrated.
Why Pets Drink Less Water in Winter
Several seasonal factors naturally reduce a pet’s thirst drive:
-
Cooler temperatures mean pets don’t feel as thirsty
-
Less outdoor activity leads to fewer hydration cues
-
Dry indoor air from heating systems pulls moisture from the body
-
Warm water bowls may be less appealing if left near heat sources
Cats, in particular, already have a low thirst drive, which makes winter hydration even more important to monitor.
Why Winter Hydration Still Matters
Even mild dehydration can affect a pet’s health.
Low water intake may contribute to:
-
Urinary tract issues
-
Constipation
-
Kidney strain
-
Dry skin and dull coats
-
Lower energy levels
In winter, these issues can go unnoticed because pets appear calmer or sleep more — making hydration easy to overlook.
Signs Your Pet May Not Be Drinking Enough
Watch for:
-
Dark yellow urine or infrequent urination
-
Dry gums or nose
-
Lethargy
-
Decreased appetite
-
Constipation
If you notice persistent symptoms, a vet visit is always a good idea.
How to Help Pets Stay Hydrated in Winter
Small changes can make a big difference:
-
Refresh water daily (and clean bowls regularly)
-
Offer multiple water stations around the home
-
Keep water away from heating vents
-
Try slightly warmer water if your home is cold
-
Add moisture to meals with wet food or broth
-
Use wide, shallow bowls — especially for cats
For multi-pet homes, make sure water access isn’t competitive or shared during illness.
Don’t Forget Bowl Cleanliness
Clean bowls play a bigger role in hydration than many people realize.
Biofilm, saliva, and residue can make water less appealing — even if it looks clean. Washing water bowls daily helps encourage pets to drink more consistently.
Hydration is Key
Winter hydration isn’t just a summer concern.
When temperatures drop and routines change, pets may drink less without us noticing. Paying attention to water intake — and making it easy and appealing — supports digestion, kidney health, and overall wellness all season long.
