When it comes to caring for our canine companions, ensuring they are comfortable in their environment is a top priority. During winter months, when temperatures can drop quite low, many pet owners wonder if their homes might get too cold for their dogs.
How cold is too cold for dogs inside the house?
There is no single temperature that is universally too cold for dogs. Dogs have a higher body temperature than humans and their fur helps insulate them and keep them warm. However, factors like breed, coat, age, health conditions and acclimation to cold can affect how well a dog handles lower temperatures.
As a general guideline, once indoor temperatures drop below 45°F for an extended period, special consideration should be given to a dog’s comfort. Very cold temperatures from 0°F to 32°F can start to be stressful for dogs not accustomed to them. And temperatures below 0°F can become dangerous if the dog is unable to stay warm and their core body temperature drops.
Signs a house may be too cold for a dog
Look for these signs that indicate your dog is having difficulty coping with the cold:
- Shivering or trembling
- Whimpering or barking more than usual
- Seeking warm spots like under blankets, behind furniture or on heat vents
- Acting anxious or restless
- Sleeping more than normal
- Loss of appetite
- Appearing stiff or reluctant to move
- Cold ears and paws
Factors that influence cold tolerance
Some dogs adapt to colder indoor temperatures better than others based on these key factors:
| Factor | Description |
|---|---|
| Breed and coat | Dogs with thicker, longer fur like Huskeys and Malamutes tend to be more cold tolerant. Short hair breeds like Chihuahuas have less insulation. |
| Age | Puppies and senior dogs have a harder time regulating body temperature. |
| Health | Dogs with conditions like hypothyroidism, diabetes, Cushing’s disease, or arthritis are more vulnerable to cold. |
| Outdoor time | Dogs who spend more time outdoors acclimate better to lower indoor temperatures versus indoor-only dogs. |
| Conditioning | Consistent exposure to colder temps can allow dogs to gradually get used to them. |
| Body condition | Dogs who are overweight or obese tend to have more insulation and retain body heat better. |
Tips for keeping dogs warm in a cold house
If your dog seems bothered by chilly indoor conditions, there are some simple ways to help them stay comfortable and warm:
Adjust the thermostat
If possible, slightly raise the temperature setting on your thermostat to better accommodate your dog. Aim for at least 65-68°F during cold snaps.
Add an extra layer of bedding
Give your dog some cozy, thick blankets or a new pillow to burrow into on their dog bed. This gives them a warm spot to sleep and rest.
Keep them active
Take your dog for regular walks and make sure they get daily activity even when it’s cold. Moving around will help raise their core body temperature.
Massage circulation
Gently massage your dog’s paws, ears and body to improve circulation to their extremities when they come inside.
Brush frequently
Regular brushing removes dirt and loose hair allowing their coat to provide maximum insulation from the cold.
Add a sweater or coat
A properly fitted dog sweater or coat provides an extra layer of warmth for dogs who need it when venturing outside in cold weather.
Use heating pads
Heating pads made for pets can be placed in your dog’s favorite resting spots to provide a warming area for them to lay on.
Adjust ventilation
Direct cold drafts away from your dog’s bed and consider closing doors to unused rooms to retain heat in their main living areas.
Offer warm water
Warm up your dog’s water slightly so they stay hydrated without an icy cold drink.
Add insulation
Keep your dog’s crate or bed in a warm corner of the room, and place blankets over the doors and walls of their crate to better insulate it.
Use a space heater
A small space heater near your dog’s bed or crate set to low or medium can provide direct ambient warmth.
Warm their food
Serve wet food at room temperature or slightly warmed to provide a heat source when your dog eats.
Deciding if your dog needs a sweater or coat
Some dogs will benefit from the extra insulation and warmth of a sweater or coat during cold spells, but others can manage fine without one. Consider the following factors when deciding if your dog needs cold weather wear:
- Very short or thin coat – These dogs have less natural insulation.
- High-risk age – Puppies and seniors have a harder time regulating temperature.
- Small breed – Tinier dogs tend to get colder more quickly.
- Medical conditions – Illnesses can increase sensitivity to cold.
- Frequent potty breaks – For dogs going out often in cold or wet weather.
- Poor conditioning – Dogs not acclimated to cold need more protection.
- High activity – Provides warmth for active outdoor dogs.
- Geriatric or stiff dogs – Helps raise body temperature and circulation.
Choosing the right coat or sweater
Pick cold weather wear designed specifically for dogs that:
- Fits properly without restricting movement
- Covers the torso from neck to tail
- Is made from a warm but breathable fabric
- Has adjustable closures like velcro or snaps for a secure fit
- Is easy to put on and take off
- Has reflectors for visibility outdoors at night
When to be concerned about the cold
In most cases, some simple adjustments are all that are needed to keep your dog comfy when temperatures drop. But seek immediate veterinary care if you notice any of the following signs of hypothermia or dangerously low body temperature:
- Severe shivering and trembling
- Lethargy, weakness or stupor
- Bright red or pale gums
- Very slow breathing or heart rate
- Low body temperature (below 99°F)
- Collapse or inability to stand
- Unconsciousness
Young puppies, elderly dogs, short-haired breeds and dogs who are underweight face the highest risk of hypothermia. But any dog can suffer cold weather-related health impacts if they cannot stay appropriately warm in frigid conditions.
Conclusion
While dogs are quite resilient in cold temperatures thanks to their fur coats and higher body heat, precautions should be taken once indoor temperatures drop below 45°F. Warning signs like shivering, hiding and lethargy indicate your home may have become too cold for your dog’s comfort. Adjusting the thermostat, adding bedding and insulation, ensuring activity and managing drafts can usually remedy the issue. For dogs who need it, a well-fitting sweater or coat can provide vital extra warmth. Stay alert for symptoms of hypothermia in severely cold conditions that require immediate veterinary treatment. With some simple planning and awareness, our furry friends can stay happy and healthy even when the thermometer plunges.
