How Cold Is Too Cold for Dogs? A Walk Temperature Guide by Size and Coat
Your husky may be begging to stay out in the snow while your whippet stands shaking at the front door. Both are telling you the truth. There is no single temperature that is "too cold for dogs"; it depends on the dog's size, coat, age, health and how wet and windy it is. The chart below gives a practical starting point, and the rest of this guide shows how to adjust it for your own dog.
Temperature guide for winter walks
These ranges reflect common veterinary guidance for healthy adult dogs. Use the feels-like temperature from your weather app, because wind and damp make cold far harsher.
| Air temperature (feels-like) | Small, short-coated, young, old or thin dogs | Medium dogs with a normal coat | Large or thick double-coated dogs |
|---|---|---|---|
| Above 7°C (45°F) | Usually fine | Fine | Fine |
| 0 to 7°C (32-45°F) | A coat helps; watch for shivering | Usually fine | Fine |
| -7 to 0°C (20-32°F) | Coat needed; keep walks to 10-20 minutes | Watch closely; consider a coat | Usually fine |
| -18 to -7°C (0-20°F) | Short toilet trips only | Short walks, 10-15 minutes | Shorter walks; watch paws |
| Below -18°C (0°F) | Toilet trips only | Toilet trips only | Brief outings only, even for northern breeds |
Treat this as a guide, not a rule. A fit, active dog moving briskly stays warmer than one standing around. A dog who is old, unwell or nervous may struggle sooner.
Which dogs feel the cold most
- Small and toy breeds: Chihuahuas, Yorkshire Terriers, Miniature Pinschers and similar lose heat quickly because they have more skin surface for their weight and sit close to cold ground and snow.
- Short, thin coats: Greyhounds, Whippets, Boxers, Dobermanns, Staffies, Dalmatians and Pointers have little insulation.
- Lean dogs: sighthounds and very fit dogs carry little body fat.
- Puppies and senior dogs: both regulate body temperature less well.
- Dogs with health problems: arthritis gets stiffer and more painful in the cold, and dogs with heart disease, kidney disease, diabetes or hormonal conditions such as hypothyroidism or Cushing's disease are more at risk. Ask your vet for advice for your dog.
- Recently clipped dogs: a fresh groom removes the coat's insulation. Ask your groomer to leave winter coats a little longer.
Dogs bred for cold, such as Huskies, Malamutes, Samoyeds, Newfoundlands and Bernese Mountain Dogs, cope much better and often enjoy snow. They can still get frostbite on ears, paws and tails in severe cold.
What makes it feel colder
- Wind chill: a 0°C day with a strong wind can feel like -7°C or below.
- Wet: rain, sleet and swimming soak the coat and remove its insulation. A wet dog in 5°C weather can chill faster than a dry dog at -5°C.
- Standing still: waiting outside a shop or at a bus stop is colder than walking.
- Snow depth: belly-deep snow chills short-legged dogs quickly.
- Sun: a sunny, still day feels warmer than the thermometer suggests.
Signs your dog is too cold
Head home when you see:
- Shivering or trembling
- Lifting paws, limping or refusing to walk on
- Hunched posture with the tail tucked
- Whining, or trying to turn back towards home
- Slowing down, seeming anxious or looking for shelter
Hypothermia: when to worry
Hypothermia means the body temperature has dropped below normal. Early signs are strong shivering, lethargy and weakness. As it gets worse, dogs become stiff, clumsy and very sleepy, their breathing and heartbeat slow, and gums may look pale. A dog that has stopped shivering while still cold is in a more serious stage, not getting better.
- Bring your dog indoors to a warm room.
- Dry them thoroughly and wrap them in warm (not hot) towels or blankets. Towels warmed briefly in the tumble dryer help.
- You can place a hot water bottle wrapped in a towel against the chest or belly. Never use a heating pad or a hairdryer directly on the skin, as cold skin burns easily.
- Call your vet. Moderate or severe hypothermia needs veterinary treatment.
Frostbite
The ears, tail tip, paw pads and, in male dogs, the scrotum are the parts most likely to freeze. Frostbitten skin may look pale, grey or bluish, feel cold and hard, and become red, swollen and painful as it warms. Warm the area gently with lukewarm (not hot) water, then pat dry. Do not rub or massage it, which damages the tissue further. Frostbite often looks worse a few days later, so always have it checked by a vet.
How to keep winter walks safe
- Go shorter and more often: two or three short walks beat one long one on very cold days.
- Walk in the warmest part of the day: late morning and early afternoon, especially for small or elderly dogs.
- Use a coat that fits: measure from the base of the neck to the base of the tail. It should cover the back and chest without rubbing under the front legs. Waterproof outer layers matter in wet climates.
- Protect paws: trim the fur between pads to stop ice balls forming, apply a paw balm before walks, or try dog boots. Rinse and dry paws after walking on gritted or salted pavements.
- Stay off frozen water: keep dogs on a lead near frozen ponds, lakes and rivers. Never go onto ice to rescue a dog; call the emergency services.
- Be visible: winter afternoons are dark. Use a reflective coat or an LED collar.
- Never leave a dog in a car: in winter a car can become as cold as a fridge.
- Feed sensibly: very active outdoor dogs may need a little more food in winter; less active indoor dogs usually do not.
When it is too cold for a walk
On the coldest days, keep the exercise indoors. Ten minutes of training, a game of hide-and-seek with treats, a snuffle mat or a food puzzle, or tug and fetch along the hallway tire most dogs out surprisingly well. Older dogs may simply appreciate a warm, soft bed away from draughts and tiled floors.
What about cats?
Indoor cats are fine with the heating on. Outdoor cats need a warm, dry shelter off the ground and access back into the house; many owners keep cats in at night during cold snaps. Cats sometimes crawl into warm car engines, so bang on the bonnet before you start the car.
