Winter is a mixed season for dogs. Many love the cold and the snow, but the months also bring real hazards that catch owners out: a sweet-tasting poison that kills, gritted pavements that hurt paws, frozen water that gives way, and dark afternoons that make walks less safe. None of it needs to keep you indoors, it just needs a bit of winter know-how. So here is how to keep your dog safe, warm, and visible through the cold months, starting with the one that is genuinely deadly.
As always, the honest note: I am a writer, not a vet, and if you suspect poisoning or your dog is unwell, call your vet immediately.
Antifreeze: the winter killer
This is the most dangerous thing on the list, because antifreeze is both appealing to dogs and lethal.
Antifreeze poisoning is the winter emergency every dog owner should know about, precisely because the sweet taste means dogs will happily drink it, and because prompt treatment is the only thing that works.
Gritted pavements and icy water
Two more winter hazards are underfoot, and both are easy to manage once you know them.
The grit and rock salt spread on winter roads and pavements can irritate and crack paw pads, and it is harmful if a dog licks it off, so wipe and dry your dog’s paws after walks, check between the pads for packed ice or grit, and rinse off any salt. A paw balm helps dogs prone to cracked pads. The other underfoot danger is ice: never let your dog onto a frozen pond, lake, or river, as the ice can give way, and a dog falling through is in serious, sometimes fatal, danger, and so is anyone who goes in after it. Keep dogs on a lead near frozen water, and pick walking routes that avoid it in icy weather.
Keeping warm, and being seen
The last two pieces are about comfort and visibility, and they matter most for the vulnerable and on dark afternoons.
Not all dogs feel the cold equally: large, thick-coated breeds often revel in it, while small, thin-coated, old, young, or unwell dogs get cold quickly and benefit from a well-fitted coat and shorter walks in harsh weather. Watch for shivering, reluctance to carry on, or lifting paws off the ground, all signs it is time to head home. Dry your dog thoroughly after wet or snowy walks, and give it a warm, draught-free bed indoors, off cold floors. And because winter walks often happen in the dark, make yourself and your dog visible with reflective or light-up gear on collars, leads, or coats, for your safety as much as the dog’s.
The bottom line is that winter is perfectly enjoyable for dogs with a little care: know the antifreeze danger and act fast if you suspect it, wipe paws after gritted walks, stay off frozen water, keep vulnerable dogs warm with a coat and shorter outings, and light yourselves up on dark walks. Do that, keep your vet’s number to hand, and the cold months stay a pleasure. For the opposite-season version of this care, see our guide on whether it is too hot to walk your dog.
Common questions
- How cold is too cold to walk a dog?
- It depends on the dog. Small, thin-coated, old, young, or unwell dogs feel the cold much sooner than large, thick-coated breeds, so there is no single figure. As a guide, take extra care below about 4C and keep walks shorter, and in freezing conditions consider a coat for vulnerable dogs and cut the walk short. Watch your dog, since shivering, reluctance, or lifting paws means it is time to head home.
- Why is antifreeze so dangerous to dogs?
- Antifreeze contains ethylene glycol, which tastes sweet and is highly poisonous, and even a small amount can cause fatal kidney failure. Spills and drips on driveways and in garages are the usual danger. Clean up any spills immediately, store antifreeze securely, and if you think your dog has had any, treat it as an emergency and call your vet at once, since treatment must be fast to work.
- Is grit or rock salt bad for dogs?
- The grit and salt spread on roads and pavements in winter can irritate and crack paw pads, and it is harmful if a dog licks it off its paws, causing an upset stomach or worse in quantity. Wipe and dry your dog's paws after winter walks, check between the pads for packed grit or ice, and rinse off any salt. Consider paw balm for dogs prone to cracked pads.
- How do I keep my dog warm in winter?
- Give short-coated, small, old, or young dogs a well-fitted coat for walks, keep walks shorter in harsh weather, and dry your dog thoroughly after wet or snowy outings. Indoors, provide a warm, draught-free bed away from cold floors. Most healthy, active dogs cope well with cold, but the vulnerable ones need help staying warm.
