How to Tell If Your Dog Is Cold: 10 Signs Your Dog May Need a Sweater.In the morning you grab your coat for your early dog walk, but what about your dog? It's easy to assume that because dogs have fur, they're naturally protected from cold weather. Some certainly handle low temperatures better than others, but a fur coat doesn't automatically make a dog comfortable in the cold. It is important to be able to reconize the sign that your dog may be uncomfortable with the cold.
Short-haired breeds, small dogs, puppies, senior dogs, lean breeds, and dogs accustomed to warm indoor temperatures may start feeling chilly much sooner than you expect.
The tricky part is that your dog can't simply tell you, "I'm cold."
Instead, you need to watch their behavior.
Here are 10 signs your dog may be cold, plus some practical advice for deciding when it's time to reach for a warm dog sweater.
1. Your Dog Is Shivering
Shivering is probably the most recognizable sign that a dog is cold.
Just like people, dogs may shiver when their bodies are trying to generate additional warmth.
A brief shiver after stepping outside doesn't necessarily mean there's a problem, but persistent trembling during a walk is a good indication that your dog may be uncomfortable.
If your dog is shivering, consider heading somewhere warmer and adding an appropriate layer before going back outside.
Keep in mind that dogs can tremble for reasons unrelated to temperature, including excitement, fear, pain, and illness. If your dog continues shaking after warming up, contact your veterinarian.
2. Your Dog Keeps Lifting Their Paws
Have you ever seen your dog suddenly lift one paw and then another while standing in the snow?
Their feet may be getting cold.
Ice, frozen ground, snow, and winter sidewalk treatments can all make paws uncomfortable.
If your dog repeatedly lifts their paws, tries to avoid putting them on the ground, or suddenly refuses to walk, don't force them to continue.
Check their paws for ice or debris and head inside if necessary.
3. They're Trying to Turn Around and Go Home
Dogs usually make their opinions fairly clear.
A dog who normally loves walking but suddenly stops, pulls toward home, or repeatedly turns around may simply have had enough of the cold.
Pay attention to changes in your dog's normal behavior rather than following a strict temperature rule.
A 30-degree day that feels wonderful to one dog may be miserable for another.
4. They're Walking More Slowly Than Usual
Cold dogs sometimes slow their pace.
You might notice your normally enthusiastic walker beginning to lag behind, especially toward the end of a winter outing.
Cold muscles can also feel stiff, which can be particularly noticeable in senior dogs.
If your dog suddenly slows down during a cold-weather walk, consider shortening the outing and warming them up.
5. Your Dog Is Hunched or Tucking Their Tail
Body posture can reveal a lot about how a dog feels.
A cold dog may:
- Hunch their back
- Lower their head
- Tuck their tail
- Hold their body tightly
- Curl themselves into a smaller shape
These positions help conserve body heat.
If your dog looks physically tense rather than relaxed and curious, the weather may be colder than they're comfortable with.
6. They're Constantly Searching for Warm Places
Your dog's indoor habits can offer clues too.
Does your dog immediately look for the warmest spot in the house after a walk?
Maybe they curl up beside a heating vent, burrow underneath a blanket, climb into your lap, or find the sunniest patch of floor.
Some dogs simply love being cozy, but an increased desire for warmth during winter can indicate that they're feeling the seasonal temperature change.
7. Their Ears and Body Feel Unusually Cold
Touch alone isn't a reliable way to determine your dog's body temperature, but it can give you additional information when combined with their behavior.
If your dog's ears and body feel unusually cold after spending time outdoors and they're also shivering or acting uncomfortable, it's time to bring them somewhere warm.
Never use a heating pad or very hot water to warm a cold dog quickly. Gentle, gradual warming is safer.
8. They're Reluctant to Go Outside
Some dogs race toward the door when they hear the word "walk."
Then winter arrives.
If your normally enthusiastic dog suddenly looks outside and decides they'd rather stay on the couch, the cold may be part of the reason.
Try adding a comfortable dog sweater and see whether your dog seems happier during their outing.
9. Your Senior Dog Seems Stiffer in Cold Weather
Senior dogs deserve special consideration during winter.
Older dogs commonly experience changes in muscle mass, circulation, mobility, and joint comfort. Cold weather can make stiffness more noticeable, particularly after they've been resting.
A comfortable 100% wool dog sweater can provide an additional insulating layer during outdoor walks.
You may also want to choose shorter walks during the coldest parts of winter and give your senior dog more time to warm up before and after exercise.
10. Your Dog Is Curling Into a Tight Ball
Dogs often curl up simply because it's a comfortable sleeping position.
But curling tightly also helps conserve heat.
You may notice your dog curling into a much tighter ball during winter, sometimes even tucking their nose underneath their tail.
Providing a warm, draft-free sleeping area can help keep them comfortable indoors.
Which Dogs Get Cold the Fastest?
Breed is only one factor.
Dogs that tend to become cold more easily include small dogs, thin dogs, short-haired breeds, puppies, seniors, and dogs with health conditions that affect their ability to regulate temperature.
Breeds that may particularly appreciate extra winter warmth include:
- Chihuahuas
- Dachshunds
- French Bulldogs
- Boston Terriers
- Beagles
- Boxers
- Dobermans
- Weimaraners
- Greyhounds
- Whippets
- Italian Greyhounds
A dog's individual tolerance matters more than the breed name alone.
When Should a Dog Wear a Sweater?
There's no single temperature at which every dog needs a sweater.
Think about the combination of temperature, wind, moisture, length of time outdoors, coat type, size, age, and activity level.
A healthy large dog with a thick double coat may be perfectly comfortable during a brisk winter walk without clothing. A small short-haired dog standing beside you at the same temperature may be shivering within minutes.
Watch your dog rather than relying only on the thermometer.
Why Choose a Wool Dog Sweater?
When your dog needs an extra layer, the material matters.
Natural wool is particularly well suited to cool-weather dog clothing because it provides insulation while remaining breathable.
Wool fibers trap air, helping retain warmth without requiring an extremely bulky garment. Wool also manages moisture naturally, which is useful when you're dealing with snow, damp grass, or unpredictable winter weather.
At Chilly Dog Sweaters, our sweaters are individually hand-knit using 100% natural wool. They're designed to provide practical warmth while still allowing dogs to walk, sniff, explore, and enjoy being dogs.
And because they're hand-knit, they're a long way from the disposable dog fashion that gets worn once for a photograph and forgotten.
A great dog sweater should look beautiful—but it should work, too.
Make Sure the Sweater Fits Correctly
An improperly fitted sweater can be just as uncomfortable as being cold.
A sweater shouldn't pull tightly across your dog's chest or shoulders, and it shouldn't be so loose that it twists around while your dog walks.
Measure your dog's chest, neck, and back and compare those measurements with the size chart before ordering.
This is particularly important for breeds with unusual proportions, such as Dachshunds, French Bulldogs, and deep-chested dogs.
Cold-Weather Walks Can Still Be the Best Walks
Winter doesn't have to mean spending months indoors.
In fact, some dogs seem to come alive when the first snowflakes start falling.
The goal isn't to keep your dog out of the cold entirely. It's to recognize when they're uncomfortable and give them the protection they need.
Pay attention to your dog's body language. Shorten walks when necessary. Protect their paws. Keep them dry. And when your dog needs another layer, choose something warm, breathable, and comfortable enough for a real walk—not just a cute picture.
A well-fitting 100% wool Chilly Dog sweater can help make those crisp winter mornings something you both look forward to.
Frequently Asked Questions
How do I know if my dog needs a sweater?
Watch for shivering, slowing down, lifting paws, a tucked tail, reluctance to continue walking, or attempts to return home. Small, short-haired, lean, senior, and very young dogs are generally more likely to need additional warmth.
Do dogs get cold even though they have fur?
Yes. Fur provides insulation, but coat thickness varies dramatically between breeds and individual dogs. A short-haired Chihuahua and a Siberian Husky have very different protection from cold weather.
At what temperature should dogs wear sweaters?
There isn't one temperature that applies to every dog. Size, coat type, age, health, wind, moisture, activity, and duration outdoors all affect cold tolerance.
