Extreme heat and cold

How to protect your pet when the weather bites.

3 min read

Pets feel temperature extremes more than we assume. Heat is the bigger danger, but cold, wet and icy streets cause real problems too. This guide explains the main risks and the simple habits that prevent most of them.

Never leave a pet in a parked car

The temperature inside a parked car rises far faster than people expect, even with the windows slightly open and even in shade or on mild days.

It can become deadly within minutes. If you cannot take your pet with you, leave it at home. If you see an animal in distress in a locked car, contact the local authorities or emergency services.

Recognising heatstroke

Heavy panting, thick drooling, bright red or pale gums, restlessness, vomiting, wobbling or collapse in hot conditions can mean heatstroke.

Move the animal to shade, offer cool water, wet the body with cool water and fan it, then go to a vet at once, even if your pet seems to recover. Internal damage can develop afterwards.

Some pets are at much higher risk: flat-faced breeds such as bulldogs, pugs and Persian cats, thick-coated and large dogs, puppies, seniors, overweight animals and pets with heart or breathing problems.

Walks and exercise in warm weather

Walk early in the morning or late in the evening.

Pavement and sand can reach temperatures that burn paws, so test the surface with the back of your hand for several seconds; if it is too hot for you, it is too hot for them. Cut down intense exercise, play and ball games in the heat, and carry water for your pet.

Always provide shade and fresh water at home and outdoors. Cool floors, a damp towel and well-ventilated rooms help. Avoid shaving a double-coated dog to the skin unless a groomer or vet advises it, since the coat also insulates against heat.

Cold weather care

Short-haired, small, very young, old and thin animals feel the cold the most.

A coat can help on walks, and limiting time outside in freezing weather is sensible. Do not leave pets outside in extreme cold, and provide a warm, dry, draught-free place to sleep.

De-icing salt and chemicals can irritate or burn paws and are harmful if licked. Wipe paws and belly when you come home. Antifreeze is highly toxic, tastes sweet to animals and must be kept out of reach; any suspected ingestion is an emergency.

Seniors and pets with health conditions

Arthritis tends to hurt more in the cold, and pets with heart, lung or kidney disease cope less well with extremes of temperature.

Adapt walks and rest areas, and ask your vet about any special precautions for your pet.

The short version

  1. Never leave a pet in a car, not even briefly: cabin temperature rises in minutes.
  2. Walk in cooler hours. Hot pavement burns paws; test with the back of your hand.
  3. Brachycephalic breeds (bulldogs, pugs, Persians…) struggle far more in heat.
  4. In cold: a coat for short coats or seniors; avoid de-icing salt on paws; dry on return.
  5. Fresh water always available. In heat, shade and no intense exercise at midday.

Frequently asked questions

Is it okay to leave my dog in the car for a minute?
No. Conditions can become dangerous very quickly, and a short errand often lasts longer than planned. It is safest to leave your pet at home.
How do I know if the ground is too hot?
Press the back of your hand on it for about five seconds. If you cannot keep it there comfortably, choose another time or surface.
Do all dogs need a coat in winter?
No. Thick-coated breeds are often fine, while small, short-haired, very young, old or thin dogs may benefit from one.
