Cold Weather and Animals: Do They Really Get Cold and How Can You Protect Them in Winter?

As temperatures drop, many pet owners ask the same question every winter: do animals feel the cold like we do? The answer is more nuanced than it seems. Not all animals experience cold in the same way, and it is not just about temperature. Humidity, wind, age, health and lifestyle all play a decisive role.

Dogs, cats, horses living outdoors, rabbits that go outside… let’s take a closer look at when cold becomes a real issue, how to protect animals effectively, and how to recognise warning signs early.

Do animals get cold? A matter of thresholds and conditions

Animals have natural mechanisms to regulate their body temperature: fur, undercoat, fat reserves and resting posture. However, these protections have limits, especially when several challenging factors occur together.

Dry cold vs damp cold: a crucial difference

A frequently underestimated factor is that damp cold is far more dangerous than dry cold. Rain, humidity, wind or a cold, wet ground surface accelerate heat loss, even at relatively mild temperatures.

Key point: an animal at 5 °C in wet and windy conditions may be more at risk than one at 0 °C in a dry, sheltered environment.

When should you start worrying? Practical guidelines by species

These figures are indicative only. Acclimatisation, body size, health and living conditions are just as important as the temperature itself.

Dogs

• Small dogs, short-haired breeds, puppies and senior dogs: increased vigilance from around 7–10 °C, especially in damp conditions.
• Robust dogs with a double coat: often comfortable down to 0 °C or below in dry weather.

Cats

• Indoor cats: more sensitive to cold, vigilance from around 8–10 °C.
• Outdoor cats: generally better adapted, but highly vulnerable to humidity and draughts.

Horses living outdoors

• A healthy, unclipped horse usually tolerates dry cold well.
• Wind + rain + clipping can pose a real risk, even when temperatures are above freezing.

Rabbits that go outside

• Extremely sensitive to humidity and draughts.
• Dry cold is only acceptable if the shelter is perfectly dry, insulated and draught-free.

How can you protect your animal effectively from the cold?

1) Adapt the environment first

Before thinking about accessories, the priority is a dry, insulated and wind-protected environment: suitable bedding raised off the ground, with insulating materials such as straw, animal bedding or specially designed thermal mats.

Warning: damp or poorly ventilated fabrics can actually increase heat loss.

2) Should you put a coat on your animal?

The answer depends on the species and the individual animal.

Dogs

• Coats can be helpful for cold-sensitive dogs, senior animals, those recovering from illness, or during long walks in wet weather.
• They should be well-fitted, breathable and removed indoors.

Cats

• Rarely necessary indoors.
• For outdoor cats, a dry, insulated shelter is far more effective than clothing.

Horses

• The need for a rug depends on clipping, age, body condition and weather conditions.
• An ill-fitting or wet rug can cause rubbing, overheating or excessive cooling.

Rabbits

• Rabbits should not be covered. Instead, the living space must be insulated, not the animal itself.

3) Nutrition and hydration also matter

In winter, maintaining body temperature requires more energy. Depending on the species and lifestyle, a slight dietary adjustment may be appropriate, without leading to overweight, which is common in indoor animals.

For animals kept outdoors, always ensure that water does not freeze.

How can you tell if your animal is cold?

Animals do not express discomfort verbally, but behavioural changes are often very clear.

Common warning signs

• Curled-up posture, actively seeking warmth
• Persistent shivering
• Unusual lethargy or stiffness
• Cold ears or paws
• In horses: tense back, permanently raised coat, gradual loss of body condition

When should you be concerned and seek help?

Exposure to cold can weaken the immune system and increase the risk of respiratory infections, joint pain and general illness.

Seek veterinary advice promptly if you notice:

• Coughing, sneezing or nasal discharge
• Marked tiredness, apathy or withdrawal
• Loss of appetite or reduced drinking
• Abnormal breathing
• Lameness or obvious pain
• Suspected hypothermia: very cold, unresponsive or “absent” animal

Important: if hypothermia is suspected, never rewarm an animal abruptly. Gradual warming and immediate veterinary care are essential.

Often overlooked winter risks

• De-icing salt: irritating and toxic if ingested; damages paw pads.
• Frozen water: check bowls several times a day.
• Engines and garages: attract cats – always check before starting a car.
• Cold floors: can worsen arthritis in older animals.
• Humidity: wet fur or damp bedding accelerates heat loss.

Conclusion

Yes, animals can feel the cold — but not all in the same way, and not under the same conditions. The real danger is often not temperature alone, but the combination of cold, humidity, wind and fatigue.

By observing your animal closely, adapting their environment and taking preventive action, you provide the best protection. A well-protected animal will cope with winter more comfortably, safely and healthily.

FAQ – What science tells us about cold and animals

Sources: veterinary recommendations (companion animals and exotic pets), physiological data on thermoregulation, and publications from animal welfare organisations regarding winter housing and care.

Very often, yes. Moisture and wind greatly increase heat loss because wet fur insulates poorly. This significantly raises the risk of hypothermia.

Animals with a dense undercoat or larger body mass lose heat more slowly. However, they are still vulnerable when exposed to damp conditions, inactivity, old age or illness.

Yes. Young animals regulate body temperature less efficiently, while older animals often have reduced muscle mass and cool down more quickly.

Only if it is appropriate. Fit, breathability and dryness are essential. An unsuitable coat can actually do more harm than good.

Cold, de-icing salt and abrasive surfaces damage the skin of paw pads, leading to cracks and infections. Rinsing with lukewarm water and using appropriate paw care can help.

Possible signs include extreme weakness, very cold extremities, slow or abnormal breathing and apathy. This is an emergency requiring immediate veterinary attention.

Not necessarily. Unclipped horses often cope well with dry cold if they have shelter from wind. Rain, wind and clipping significantly change their needs.

Only under optimal conditions: a completely dry, insulated, draught-free and secure enclosure. Humidity represents a major risk for rabbits.

Dry the belly and paws thoroughly and provide a warm, dry resting place. In the following days, monitor for coughing, lethargy or reduced appetite.
