Why Your Pet Drinks Less Water in Winter (and How to Keep Them Hydrated)

When temperatures drop, many pet parents notice something surprising: their dog or cat suddenly isn’t drinking as much water as they normally do. It can feel a little concerning, especially if you’re used to filling the water bowl multiple times a day during the warmer months. The good news? A decrease in water intake during winter is very common, and in many cases, completely normal.

Still, hydration plays a huge role in overall wellness, so understanding the “why” behind seasonal shifts can help you support healthy habits all winter long.

Why Pets Drink Less Water in Winter

There are several reasons your dog or cat may naturally drink less once cold weather arrives. Some of the most common include:

1. Cooler Temperatures Reduce Thirst

Heat is one of the biggest drivers of thirst. During summer, pets lose more moisture through panting, activity, and higher outdoor temperatures. In winter, their bodies simply don’t have to work as hard to stay cool, so they may not feel as thirsty.

2. Lower Activity Levels

Many pets slow down a bit in colder weather, especially if they dislike rain, snow, or chilly winds. Less running and playing means less panting and less need for water intake overall.

3. Dry Indoor Air

While cold temperatures reduce thirst, indoor heaters can create dry air, which may contribute to mild dehydration if pets aren't drinking consistently. This contrast (less thirst + drier air) can make hydration feel out of balance.

4. Snow Isn’t a Substitute for Water

Some dogs try to “drink” by eating snow during outdoor time. While occasional snow eating is common, snow doesn’t replace the hydration of fresh, clean water. In some dogs, eating snow can even further decrease their interest in drinking from a bowl.

When Lower Water Intake Is Normal vs. When to Pay Attention

A small seasonal decrease in water consumption is typically expected. However, keeping an eye on your pet’s habits is always a good idea. Contact your veterinarian if you notice unusual or concerning changes such as:

• Refusing water entirely
• Lethargy or decreased appetite
• Noticeable changes in bathroom habits
• Signs of discomfort

Veterinarians are the best source for guidance if hydration issues persist or if you’re unsure whether the changes are seasonal.

How to Encourage Healthy Hydration in Winter

Even though a slight dip in water intake is common, supporting consistent hydration is important for overall wellness, especially for pets on dry diets or those who spend a lot of time indoors.

Here are simple ways to help keep water intake steady:

1. Offer Fresh, Clean Water Daily

Pets may turn away from water that’s been sitting too long or has collected dust, debris, or pet hair. Refresh the bowl at least once a day, or more if needed.

2. Keep Water Bowls Away From Drafts

If the bowl is in a chilly spot of your home, your pet might avoid it. Try placing water in a warm, comfortable area they frequent.

3. Add Warmth to Winter Meals

Many pets are more interested in water when it’s paired with food. Try adding warm water or a pet-safe topper to their meals to promote moisture intake.

4. Consider a Pet Fountain

Flowing water can be especially appealing to cats and picky drinkers. Fountains can encourage natural drinking habits year-round.

Winter Hydration Is About Balance

If your pet is drinking a bit less water this winter, you’re not alone. It’s a natural seasonal shift for many dogs and cats. As long as they seem comfortable, active, and otherwise themselves, a slight decrease in thirst is typically nothing to worry about.

By refreshing water regularly, keeping bowls easy to access, and supporting overall daily wellness, you can help your pet stay hydrated and healthy through all the colder winter months.
