As temperatures drop, it’s natural to wonder: can my dog actually handle the cold? The answer isn’t the same for every pup. 

Some dogs are built for snow days, while others need a little extra winter love. This guide breaks down how genetics, size, and environment affect cold tolerance — plus a few practical, vet-informed tips to keep your dog safe, cozy, and happy all winter long.

How your dog’s genetics shape their cold tolerance

Not all dogs are built for winter — and the reason is written in their DNA. A dog’s breed (or breed mix) plays a major role in cold tolerance, from coat type to metabolism.

Breeds like Siberian Huskies, Alaskan Malamutes, Akitas, and Chow Chows evolved genetic traits that help them thrive in low temps: double coats, insulating underlayers, smaller ears to reduce frostbite risk, and higher body fat.  

By contrast, breeds like Chihuahuas and Greyhounds are bred for warmer environments. Even small dogs with fluffy coats like Pomeranians can struggle in extreme cold — their metabolisms just can’t keep up.

Curious how your dog’s genetics shape their winter needs? A DNA test can help you tailor their care.

What’s your dog’s cold tolerance?

Graphic titled “Cold tolerant breeds” highlighting dogs well adapted to cold weather. Examples include Siberian Husky, whose double coat and fur-covered ears help protect against frostbite; Saint Bernard, whose large size and muscle mass help generate heat and slow heat loss; and Great Pyrenees, whose insulating coat and large guardian-breed build support cold endurance. A footer notes that double coats, ear and coat features, cold-adapted metabolism, and body shape help dogs retain heat in cold conditions. Graphic titled “Cold sensitive breeds” listing dogs that are more affected by cold weather. Examples include Chihuahua, which loses heat quickly due to small body size; Greyhound, which has a thin coat, lean frame, and low body fat; and French Bulldog, which has a single coat, exposed skin, and a flat face that can make breathing harder in the cold. A footer notes that single or thin coats, exposed skin, small or lean bodies, and flat faces increase cold sensitivity.

Other things that impact cold tolerance

Breed isn’t the whole story. These factors also play a role in how your dog handles cold weather — and they’re worth reviewing with your vet.

  • Age: Puppies and seniors can’t regulate their body temperatures as well as healthy adult dogs. 
  • General health: Dogs with health conditions or arthritis may be more susceptible to cold intolerance.
  • Conditioning: Movement generates body heat, so active dogs will stay warmer in the cold.
  • Acclimatization: Even breeds like Huskies need time to acclimate if they’re new to cold outdoor weather.

How cold is too cold? The facts about dog winter care

There’s no single temperature that’s safe — or unsafe — for every dog. Cold tolerance depends on genetics, size, coat, age, and conditioning. But most leading veterinary organizations recommend these general guidelines:

  • Below 32°F: Use increased caution for small breeds, dogs with thin coats, or very young, old, or sick dogs who may experience early hypothermia.
  • Below 20°F: Temps may be hazardous for small- and medium-sized dogs. Large dogs and northern breeds may be able to tolerate longer walks, but frostbite risk rises for all dogs.
  • Below 0°F: Temps may be life-threatening for many dogs within minutes, especially if it’s windy or wet. 

Can my dog go outside today?

There’s no single right answer, but this table offers a helpful snapshot to assess today’s conditions alongside your dog’s breed, coat, and cold tolerance.

Chart titled “How cold is too cold?” showing dog cold-weather safety by temperature. Above 45°F is safe for all dogs. From 32–45°F, small, senior, and thin-coated dogs need caution. From 20–45°F, medium and large dogs have lower risk. From 0–20°F, cold can be dangerous for all dogs, with northern breeds tolerating brief exposure. Below 0°F is potentially life-threatening for all dogs; even northern breeds should only go outside briefly. A note states that wind, moisture, inactivity, age, and health increase risk.

Most dogs inherit a mix of traits. Find out how your pup handles the cold with an Embark DNA test.

Don’t forget about wind chill and exposure

The temperature on your weather app doesn’t tell the whole story. Wind, moisture, and inactivity can make cold conditions far more dangerous.

  • Wind chill: Wind increases the rate of heat loss from your dog’s body.
  • Dampness: Wet fur doesn’t insulate well, and evaporation removes body heat.
  • Cloud cover: A cloudy day that blocks direct sunlight makes your dog feel colder.
  • Inactivity: Activity generates heat; dogs that are inactive outside get cold faster.

How do I know if my dog is too cold?

Regardless of your dog’s breed, you’ll want to watch how they handle the cold. Signs like shivering, whining, anxiety, refusing to walk, lifting paws, or searching for warm places may mean they’re getting cold. Grey skin patches, pale gums, cold extremities, or lethargy may be signs of frostbite or hypothermia: call your vet ASAP.

Your winter walk safety checklist

Heading outside? Use this quick winter dog safety checklist before, during, and after every walk. 

Before the walk

  • Protect those paws. Rub with a balm like Musher’s Secret to avoid ice melt and salt burn.
  • Have a sweater and booties handy. Check out these cozy winter accessories.
  • Use puppy training pads on frigid days. New puppies are more susceptible to cold than adult dogs. 

During the walk

  • Avoid exposure to toxic substances. This includes ice melt and antifreeze!
  • Leash your dog in bad weather. It’s easier for a dog to get lost in winter conditions. 
  • Watch for frostbite and hypothermia. Look for cold ears, skin discoloration, and lethargy.

After the walk

  • Towel-dry after snow play. Ensure they stay cozy and avoid skin irritation.
  • Clean paws and tummy of ice and snow. Rinse with warm water to prevent ingestion of ice melt. 
  • Heat and humidify indoor spaces safely. Don’t use heating pads as they can pose burn risks.

All winter long

  • Fuel up for warmth. Cold burns calories and stiffens joints. Talk to your vet about diet changes. 
  • Let their coat grow — and don’t forget to brush! Shaving destroys natural insulation; brushing thickens coats.

A note about snow-eaters: Hey, a little fresh snow is okay. But avoid plowed areas and parking lots; chemical toxins may lead to gastrointestinal issues. Offer warm water before you head out, and your dog won’t be as interested in snow.

Infographic titled “Which dogs are built for snow?” summarizing survey results from the Embark dog community linked to genetics. Medium-muzzle dogs (BMP3 gene) show the highest enjoyment of snow, with 77% loving it. Dogs with facial hair (RSPO2 gene) have 63% positive responses. Heavy shedders (MC5R gene) are most likely to enjoy snow at 83%. Hairless dogs (FOX13 or SGK3 genes) show low tolerance, with only 6% approving of snow.

Have indoor activities prepared to prevent winter blues

Cabin fever isn’t just a human problem — dogs feel it too. When winter limits outdoor time, dogs can get restless and destructive. Prevent boredom and improve winter dog health with these enriching activities:

  • Mental skill boosters: Keep your dog mentally sharp with food puzzles, scent games, and DIY obstacle courses that’ll spark their natural problem-solving instincts.
  • Training refreshers: Prevent skills from fading with short, focused sessions that reinforce commands, teach new tricks, and strengthen your bond.
  • Outdoor play change-ups: For winter-loving dogs, try new activities like snow mazes and scavenger hunts with hidden treats, all while keeping paws safe in the cold.

Frequently Asked Questions about winter dog safety 

What are signs of hypothermia? I’m worried about keeping my dog warm in winter.

Hypothermia is a serious winter dog safety hazard: it occurs when there is a steep drop in body temperature due to freezing temps. The first sign is shivering, although this may subside as your dog becomes even colder. Watch for lethargy, tiredness, and slow breathing. If you suspect hypothermia, see your vet right away.

If I suspect frostbite, what are some dog winter care tips about what NOT to do?

If your dog’s skin becomes discolored and is cold, hard, brittle or painful to the touch — especially on their paws, ears, tail, nose and eyelids — they may be showing signs of frostbite. Make sure not to rub, massage, or use ointments on affected areas, and don’t apply direct heat or hot water. Instead, pat them dry, keep them warm, and call your vet.

How do I protect my dog’s paws on outdoor walks? Any dog cold weather tips?

Waterproof booties are best for protecting against ice, salt and chemicals. Here are some other dog cold weather tips:

  • Rub paws with a balm for protection and moisture, before heading out.
  • Wipe or wash paws after walks to remove ice balls and de-icing salts.
  • Trim hair between toes to prevent ice buildup.
  • Avoid antifreeze spills and slippery metal grates on your walk.

In terms of winter dog safety, when is it too cold for walks?

Cold tolerance varies by breed, size, coat, age, physical condition and acclimation — and is influenced by environmental factors like wind and moisture. That said, most leading veterinary organizations recommend these general winter dog health guidelines (even for Northern Breeds):

  • Below 32°F: Caution is needed for older, smaller, and thin-coated dogs who may show early hypothermia.
  • Below 20°F: Hazardous for many dogs; frostbite risk rises for all dogs.
  • Below 0°F: Life-threatening for many dogs within minutes, especially if windy or wet.

What kind of dog winter care does my pup need, when it comes to grooming?

It’s best to let your pup’s hair grow in the winter and brush well for matting; their coat provides natural insulation and brushing helps thicken it. For best dog winter care, experts recommend less frequent bathing (every 4 to 6 weeks) and using moisturizing shampoo to combat dry skin.

Are there any winter dog safety guidelines about walking dogs when it’s snowing or raining? 

Despite the cold, your pup needs daily walks to keep them happy and healthy — even if it’s a quick romp in rain or snow. Watch out for wet weather, though: getting wet will chill your dog faster. Always towel them off as soon as you get back inside, as part of your dog winter care routine.
