How cold is too cold for a dog? Winter walks explained

There is no single temperature at which a dog feels the cold: it depends on its size, coat, age and health. One benchmark does come up in veterinary advice, though: below 0 °C, there is a risk of frostbite, and small dogs, short-coated dogs, puppies and older dogs should then only go out for short walks. Here is how to tell whether your dog is cold, how long to walk it in winter and what to do to keep walks safe.

At what temperature does a dog feel cold?

The American Kennel Club (AKC) quotes vet Sarah Wooten, who says “there is no one-size-fits-all rule”: every dog copes with the cold differently. The guidance published by the AKC still gives a useful steer:

  • Below 0 °C (32 °F), dogs are at risk of frostbite, according to Dr Jerry Klein, the AKC’s chief veterinarian. His simple test: if it is too cold for you, it is probably too cold for your dog.
  • Small dogs (Chihuahua, Miniature Poodle, Maltese, hairless breeds…): below 0 °C, outings of roughly 10 to 15 minutes.
  • Large double-coated dogs (Husky, Samoyed, Malamute, Newfoundland, Bernese Mountain Dog…): usually 30 minutes to an hour below 0 °C, or even longer for healthy Nordic breeds used to the cold.

These durations are rough guides, not official thresholds. Wind, damp and rain make the cold feel much harsher: a wet dog loses heat far more quickly, and the AKC points out that wet areas of the body are more vulnerable to frostbite.

Dogs most sensitive to the cold

According to the AKC and the PDSA (the UK veterinary charity), some dogs lose heat more quickly:

  • small dogs, which have little body mass to hold on to heat;
  • short- or thin-coated dogs, and those without an undercoat;
  • puppies, especially very young ones (the AKC advises keeping puppies under eight weeks out of extreme weather);
  • older or unwell dogs: the PDSA notes that cold weather can make stiffness and arthritis worse in senior pets.

Nordic breeds such as Huskies and Malamutes are less prone to frostbite, but the AKC stresses that no breed is completely immune.

ProfileOutings in cold weather (below 0 °C)Useful precautions

Large double-coated dogUsually 30 min to 1 hourCheck paw pads, dry off afterwards

Signs that your dog is too cold

Cold becomes dangerous when it leads to hypothermia (a drop in body temperature) or frostbite (tissue damage). According to the AKC, hypothermia is mild when body temperature is roughly between 32 and 37 °C, moderate between roughly 28 and 32 °C, and severe below that.

The first signs to look out for on a walk:

  • shivering and a dog that curls up;
  • a dog that slows down, lifts its paws, or tries to head home or find shelter;
  • later on: lethargy, slower reflexes, paleness, and breathing that becomes slow and shallow.

Frostbite affects the extremities first, those furthest from the heart: ear tips, tail, nose and paws. The AKC describes skin that is cold, pale, bluish or greyish and painful to the touch, sometimes swollen, followed by blisters or blackened skin. It can develop in as little as 30 minutes in extreme conditions.

What to do if you think your dog is too cold

  • Get it somewhere warm as soon as possible and limit its movement.
  • Call your vet straight away.
  • If you suspect frostbite, do not rub the area and do not apply direct heat (hairdryer, hot-water bottle, heating pad), as the AKC advises.

Preparing for a walk in very cold weather

A coat for dogs that need one

The PDSA recommends a good winter coat to keep your dog warm on cold walks, particularly for thin-coated, older or unwell dogs. The AKC reminds owners that clothing complements careful supervision rather than replacing it. If your dog wears a coat under its harness, remember to readjust the straps: the extra thickness changes the fit, and a harness that is too tight hampers movement. Our article on adjusting a harness on a long-haired dog explains how to check the fit.

Set off dry and pick the right time

  • Make sure your dog is completely dry before going out: a damp coat increases the risk of frostbite.
  • Walk in daylight where you can: the PDSA advises daytime walks whenever possible, as hazards are harder to spot in the dark.
  • In very cold weather, split it up: several short outings are better than one long walk for a small or older dog.

Being visible in the dark

In winter, some walks inevitably happen after dark. The PDSA suggests LED collars, hi-vis leads and coats, plus a good torch, and advises against letting your dog off the lead after dark. A harness with reflective strips, such as our reflective harness, helps make your dog more visible in headlights.

Snow, salt and ice: protecting paw pads

Paw pads take a battering in winter. The PDSA’s advice:

  • Road salt and grit irritate paws: rinse them when you get home if they have been in contact. A thin layer of paw balm can help prevent cracking.
  • Snow: trim the hair between the pads to reduce snowballs, and soak off any that remain in warm water rather than pulling them off. Boots can help if your dog will tolerate them.
  • Ice: frozen surfaces cause slips, which are particularly risky for dogs with arthritis.
  • Frozen ponds: dangerous but tempting for an excited dog; keep it on the lead nearby.
  • Antifreeze: extremely toxic to animals. If you think your dog has licked some, contact your vet immediately, without waiting for symptoms.

Once home, dry your dog, and its kit too: a damp harness left on will chill the animal. Our tips on drying a harness after a walk in the rain apply after snow as well.

Keeping your dog active when walks get shorter

Shorter walks do not mean cutting out exercise. The PDSA warns against letting your dog become a winter couch potato: if walks are shorter, make up for it with indoor games, and adjust food portions if your dog is burning less energy. Sniffing games, hunting for hidden treats or short training sessions keep a dog well occupied on very cold days.

Frequently asked questions

My dog is shivering on a walk: should we head home?

Shivering is one of the first signs of cold noted by the AKC. Cut the walk short, get your dog under cover and contact your vet if it stays lethargic or keeps shivering once warm.

Do all dogs need a coat in winter?

No. A healthy large dog with a double coat usually manages without one. Coats are mainly useful for small dogs, short- or thin-coated dogs, older dogs and those who are unwell.

Can you walk your dog in the snow?

Yes, as long as you adapt the length of the walk to your dog, check its paw pads and dry it thoroughly when you get back.
