Caution. A floppy, sleepy, cold dog who has stopped shivering, pale gums, pale grey hard skin on the ears, tail or pads, or vomiting and wobbling after licking his paws or drinking from puddles: ring your own vet today. Warm him gradually with blankets, never with direct heat.
Noticed something different about your dog? Go straight to their vet.
Do not look for the answer in a Facebook group, on TikTok or on a forum. Look for someone trained for this: your dog's own veterinarian, the only person who can examine, investigate and treat them.
- The same sign, dozens of causes. A dog that vomits may have eaten grass or may have an object stuck in the gut. From two lines you typed, nobody can tell which. The vet feels the abdomen, takes the temperature, runs tests.
- Nobody on the internet sees your dog. They see a photo and a story. A diagnosis comes from an examination and investigations, not from a resemblance to someone else's dog.
- In groups you hear from the people whose dog "got better on its own". Those for whom it ended badly rarely post again. What you read there is a selection, not a statistic.
- Doses are calculated by weight and species. Human medicines that look harmless, paracetamol or ibuprofen, are toxic to dogs. "I gave mine half a tablet" is the most dangerous advice you can get.
- Hours matter. With a twisted stomach, a poisoning or a urinary blockage, the time spent asking online is exactly the time that decides the outcome.
- The vet is accountable for what they say. They have your dog's record, history, vaccinations, past treatments. An anonymous account has none of that and answers for nothing.
Use this page to know what to observe, what to note and what to ask at the appointment, not to treat at home. If you still have doubts after a consultation, ask another vet or a specialist (dermatologist, internist) for a second opinion, not a group. And if you do not have a regular vet yet, find one now, while your dog is healthy: how to choose a veterinary clinic.
January, minus ten, and your short-coated dog is shivering ten minutes into the walk. He lifts one front paw and then the other, as if the snow were burning him. Or your outdoor dog spent a night of blizzard in his kennel and is moving stiffly in the morning. Or, after a pavement covered in grit, he licks his paws until they bleed. Winter brings three separate problems. The first is cold pulling his body temperature down, which is hypothermia. The second is frostbite on the ear tips, tail or pads. The third is irritation from road salt and de-icers. This page covers when it is urgent, what to look for and what not to do at home, because some winter "remedies" do more harm than the cold.
Dogs do not cope with cold equally. A husky or a Carpathian Shepherd with a dense coat is fine outside at temperatures that have a greyhound, a Chihuahua or a Boxer shivering within minutes. The most at risk are small dogs and short-coated dogs without an undercoat. After them come puppies and old dogs, thin or ill dogs (heart, kidneys, thyroid), wet dogs and dogs standing still in the wind. A wet dog at minus two in the wind loses heat faster than a dry one at minus ten.
When should you ring the vet today?
Go to the vet or ring now if you see any of these:
- strong shivering that does not stop once you are indoors and he is dry;
- he is floppy, sleepy, slow to react, stumbling or will not get up;
- the shivering has stopped but he is still cold and flat, which is a bad sign: his body has run out of energy even to shiver;
- pale or grey gums, slow and shallow breathing;
- a rectal temperature below 37.5 °C, if you have a thermometer (normal is 38 to 39.2 °C);
- skin on the ear tips, tail, scrotum, toes or pads that is pale, grey or bluish, cold and hard to the touch, and does not regain its colour once warmed;
- skin that turns red, swollen, very painful or blistered once warmed, or goes black over the following days;
- deep cracks in the pads that bleed, or a dog who limps after the walk;
- vomiting, great thirst or wobbliness after licking salty paws or drinking from puddles in the street. Antifreeze tastes sweet and is highly toxic; our guide for a dog who has swallowed something covers it.
Until you get to the vet
Take him into a warm room and dry him thoroughly with towels. Wrap him in blankets or towels warmed on the radiator, warm and no more, and leave his head uncovered. If he is conscious and swallowing normally, offer lukewarm water. Keep him wrapped on the way. Warm him gradually, with things that hold heat close to his body, and never put anything hot directly on him.
What should you check at home after a walk?
Two minutes after every winter walk
- Paws. Spread the toes and look between the pads for balls of ice, salt, grit, cracks or redness. Wash the paws in lukewarm water and dry them well, between the toes too.
- Ears and tail. Feel them. The tips can be cold, but they should be soft rather than hard, and indoors the colour comes back within a few minutes.
- How he is behaving. Is he licking his paws constantly? Limping? Still shivering half an hour after coming in?
What to write down
- the temperature outside, the wind, how long the walk lasted and whether he got wet;
- how many minutes in he started shivering or lifting his paws;
- where the problem is and what the skin looks like (a photo that day and another the next, if you suspect frostbite);
- what has been put down on your route, salt or coloured granules outside the flats;
- any coughing, vomiting or diarrhoea after the walk.
Telling them apart
| What you see |
What it may be |
How you can tell |
| Shivering, lifting paws, looking for shelter |
Cold, mild hypothermia |
Passes in 15–30 minutes indoors once dry |
| Floppy, sleepy, no longer shivering, cold |
Moderate or severe hypothermia |
Does not recover indoors: emergency |
| Ear or tail tip pale, cold, hard |
Frostbite |
Colour does not return; hours later, redness, pain, blisters |
| Red, cracked pads, licking constantly |
Irritation from salt or cold |
Improves after washing and a rest; keep an eye on them |
| Vomiting, thirst, drooling after a walk |
Salt swallowed while licking, or antifreeze |
Antifreeze is an emergency even with no signs |
| An old dog shivering even indoors |
Cold, but also pain or a hormonal or heart condition |
Book a check-up |
What will the vet check?
- Rectal temperature, several times, to see how cold he is and how he responds to warming. Sometimes a special low-reading thermometer is needed.
- Heart, blood pressure, breathing. Cold slows the heart and can upset its rhythm, so the vet may put him on a monitor.
- Blood tests. Blood sugar, because puppies and small dogs run out of reserves quickly, and electrolytes; sometimes clotting and kidney function.
- Controlled warming. Warm-air blankets, warmed drips and, in severe cases, other methods, at a closely watched pace. Warming too fast is dangerous as well, which is why it is done under supervision.
- Frostbite. The vet assesses it after warming and usually waits a few days to see what tissue survives. Dead skin marks itself off within one to two weeks, and only then is it decided whether it needs surgical cleaning. Pain relief and infection prevention are the vet's choice.
- Cracked or chemically burnt pads. Cleaning, sometimes a dressing, then protection while they heal.
- What lies behind it, if a dog now gets cold more easily than he used to: thyroid, heart, weight loss, age.
What should you not do at home?
- Do not rub frostbitten areas, whether with your hand, with snow or with a rough towel. The tissue is fragile and rubbing destroys it.
- Do not put hot things directly on him: hot water bottles, a hairdryer on a hot setting held close, an electric heat pad, a hot bath. Cold skin cannot feel a burn, and suddenly warming the skin can drop his blood pressure.
- Do not let a frostbitten area freeze again once it has been warmed. That is worse than leaving it cold until you reach the surgery.
- Do not put human creams, alcohol or ointments on frostbite or cracked pads without asking the vet. He will lick them off and swallow them.
- Do not let him lick his paws after the walk until you have washed them. Swallowed salt irritates the stomach and in large amounts is toxic.
- Do not let him drink from puddles in the street or in car parks in winter. Antifreeze leaking from cars tastes sweet.
- Do not give him human painkillers. Many are toxic to dogs.
Prevention, which matters more than all of the above
- Shorter, more frequent walks on very cold days, especially with small or short-coated dogs, puppies and old dogs. Keep moving, and do not stand about in the wind.
- A coat for short-coated, thin or small dogs: waterproof outside, lined inside and long enough to cover the chest and belly. A husky does not need one.
- Paw protection. Boots are worth practising at home for a few days beforehand, with tasty treats, because the first steps in them look comical. The alternative is a protective paw wax put on before you go out. Trim the long hair between the toes short, so ice balls do not build up.
- Washed and dried paws after every walk on salted pavements.
- A dry dog going out, kept away from water. On half-frozen lakes and rivers the ice gives way, and a dog cannot climb out on his own.
- Outdoor dogs. The kennel is raised off the ground, insulated and out of the wind, with the entrance facing away from it, dry straw inside (blankets get wet and freeze) and small enough for his own body to warm it. Check the water twice a day so it has not frozen. Feed more in winter, because cold burns calories. In a hard frost, small, old or ill dogs come into the house or a heated outbuilding.
- Never hours in a cold car. In winter a car cools down like a fridge.
At our winter training sessions, the dogs wait between trails on a dry blanket or in the car, not lying on tarmac or ice, and we check their paws at the end. It takes a minute and is worth doing after any winter walk.
Frequently asked questions
What dog owners search for most often on the internet about this problem, with the short answer. The answers are a guide only: the decision belongs to your dog's own vet, after an examination.
How can I tell my dog is cold?
He shivers, tucks his tail, lifts his paws off the snow in turn, slows down, looks for shelter or pulls towards home. That is your cue to cut the walk short. If the shivering does not stop indoors once he is dry, or he turns floppy and sleepy, ring your own vet: it may be hypothermia.
What temperature is too cold for a dog?
There is no single figure that fits every dog. A northern breed with a thick coat is comfortable at minus ten, while a small short-coated dog shivers a few degrees above zero. Wind and being wet make a big difference. Watch your dog rather than the thermometer: shivering and lifted paws tell you when he has had enough.
What does frostbite look like in dogs?
The affected skin, usually the ear tips, tail, scrotum or pads, is pale, grey or bluish at first, cold and hard. After warming it turns red, swollen and painful, sometimes with blisters, and over the next few days it may go black. Do not rub it; warm it slowly and see the vet.
Is road salt bad for dogs?
Yes. It dries and cracks the pads, and a dog who licks his paws swallows it and can get vomiting and diarrhoea; in large amounts it is toxic. Wash his paws in lukewarm water and dry them after every walk, use paw wax or boots, and do not let him drink from street puddles.
Does my dog need a coat in winter?
Yes if he is small, short-coated with no undercoat, thin, a puppy or old: a waterproof, lined coat that covers the chest and belly. Northern breeds and dogs with dense coats usually do not need one. The coat must be dry, because a wet one chills him more than no coat at all.
