With the arrival of cold weather, turning on the heating becomes a daily gesture. However, what comforts us can pose certain risks for the animals that share our home. Dogs and cats have a different relationship with heat: their thermoregulation, skin and behaviours make them more vulnerable to some problems that are not always obvious.
Why heating can affect pets
Heating is not, in itself, dangerous. The problem arises when the environment it creates is extreme: excessively high indoor temperatures, overly dry air or sudden temperature variations between indoors and outdoors. Animals, unlike humans, cannot easily adjust their clothing or communicate that they are too warm. Moreover, they usually rest on the floor, where temperature differences can be more pronounced.
The danger of burns from direct heat sources
Radiators, electric heaters, fireplaces and underfloor heating can cause burns on the paws and skin of animals, especially if they remain lying very close for hours. Dogs and cats instinctively seek warmth, but do not always perceive that the temperature is too high until damage has already occurred. Short-haired or hairless breeds are particularly sensitive. To avoid this, it is advisable to place barriers or maintain a minimum distance between heaters and the pet's usual resting places.
Dry air and its effects on skin and coat
Central heating systems significantly reduce indoor air humidity. In a heated home, relative humidity can fall below 30%, while the recommended level is between 40% and 60%. This dry air directly affects the skin and coat of dogs and cats: scaling, itching, dull or brittle fur appear, and in more serious cases, dry skin dermatitis. Using a humidifier in the rooms where the pet sleeps can make a notable difference. It is also advisable to ensure that the animal always has access to fresh water, as heating increases hydration needs.
Sudden temperature changes
In winter, the contrast between indoor warmth and outdoor cold can exceed 15 to 20 degrees in a matter of seconds. This abrupt change subjects the pet's immune and respiratory system to considerable stress. Older animals or those with respiratory conditions are most vulnerable. A good practice is not to take the dog directly from the warm sofa to the cold street: a few minutes in a less heated area of the house can help with the transition.
Most vulnerable groups
Not all animals react the same way to the effects of heating. Puppies and senior animals have a less efficient thermoregulation capacity. Brachycephalic breeds (bulldog, pug, Boston terrier) have greater respiratory difficulties with dry and warm air. Cats with kidney diseases need constant hydration, and dry air can worsen their condition. Wet food can help maintain adequate hydration during heating months.
How to create a safe home environment in winter
Some simple adjustments allow the heating months to be comfortable and safe for the whole family:
- Keep the indoor temperature between 18 and 21 °C, avoiding overheating.
- Move your dog's bed or your cat's bed away from direct heat sources.
- Use a humidifier to keep air humidity between 40 and 60%.
- Make sure fresh water is always available with a suitable bowl or water dispenser.
- Regularly check the condition of the skin, paws and coat.
- Consider supplements for skin and coat if you notice dryness or flaking.
With this care, heating can coexist without problems with your animals' wellbeing throughout winter.
When your pet goes outside in winter, its paws are also exposed to risks. Read our guide on how to protect your dog's paws from cold, salt and mud.
