Cold Weather Pet Safety: Winter Care for Dogs, Cats, and More
Veterinary references checked with PetHealth+ · Last reviewed June 2026
Dogs in winter
Northern breeds tolerate cold better than whippets or Chihuahuas, but no dog should be left outside indefinitely in freezing weather. Coats help short-haired dogs; wet fur loses insulating ability quickly. Walk during daylight when possible. Ice balls form between toe pads on long-haired breeds — keep fur trimmed. Booties look silly but prevent salt burns and cuts from hidden ice.
Cats and outdoor access
Cats may seek warmth under car bonnets — knock on the hood before starting the engine. Antifreeze has a sweet taste cats find attractive; even small amounts are fatal. Microchipped cats still need visible ID if snow disorients them. Provide a sheltered, insulated outdoor box if they refuse to stay in, but indoor access is safest during severe cold snaps.
Small pets and rabbits
Hutches must be raised off wet ground, wrapped or moved into sheds/garages during freezes, and stocked with extra straw bedding. Water bottles freeze — check twice daily or use insulated covers. Guinea pigs and rabbits suffer rapidly in damp cold; bring them indoors when temperatures drop below freezing for extended periods.
Cars and chemicals
Cars cool quickly and become refrigerators. Never leave pets unattended in vehicles in winter any more than in summer heat. Rock salt on pavements irritates paws and poisons if ingested during licking — rinse thoroughly. De-icers and windshield fluids contain toxic chemicals; store safely.
Recognising emergencies
Hypothermia — Shivering that stops as condition worsens, weakness, dilated pupils, slow heartbeat. Frostbite — Pale, cold skin on ears, tail, and paws turning red or black as tissue dies. Warm gradually with blankets and contact your vet — do not rub affected areas or use direct heat.

Frequently asked questions
How cold is too cold for dogs?
Risk varies by breed, coat, and health — small, thin-coated, or elderly dogs may struggle below 0°C; use shorter walks and coats when needed.
Can cats stay outside in winter?
Outdoor cats face frostbite, antifreeze poisoning, and hypothermia — provide shelter or keep them indoors during extreme cold.
Is road salt harmful to pet paws?
Yes — salt and grit irritate pads and are toxic if licked; rinse paws after walks and use pet-safe balms or booties.
What are signs of hypothermia in pets?
Shivering, lethargy, stiff muscles, pale gums, and slowed breathing — wrap in warm blankets and seek emergency vet care.
