Yes, dogs can get cold at night. How quickly a dog becomes uncomfortable depends on factors such as breed, coat type, age, size, health, sleeping environment, and the overnight temperature.
Dogs with thick double coats may tolerate cooler conditions better than short-haired or small dogs. Puppies, senior dogs, underweight dogs, and dogs with certain medical conditions may feel cold more easily and need additional protection.
Learning to recognize the signs that your dog is cold can help you create a safer and more comfortable sleeping environment. Pet parents who travel in an RV or leave pets in a temperature-sensitive space can also use a Waggle Pet Temperature Monitor to monitor environmental conditions remotely.

Why Do Dogs Get Cold at Night?
Temperatures often fall after sunset, and floors, windows, doors, and poorly insulated rooms can become noticeably colder overnight. Dogs sleeping near drafts or directly on tile, wood, concrete, or other cold surfaces may lose body heat more quickly.
Although dogs have fur, their coats do not provide equal protection. Some breeds have dense undercoats developed for cold climates, while others have short, thin coats that offer relatively little insulation.
A dog’s body temperature can also drop when they remain still for a long period. This is why a dog that appears comfortable while active during the evening may seek blankets, curl tightly, or move to a warmer location once it settles down to sleep.
Factors That Affect a Dog’s Cold Tolerance
Every dog responds to cold differently. The following factors can influence how comfortable your dog feels at night.
Breed and Coat Type
Dogs with thick double coats generally retain body heat more effectively than dogs with short, fine, or single-layer coats. Northern breeds may be comfortable in cooler conditions, while breeds such as Greyhounds, Chihuahuas, Dobermans, and other short-haired dogs may need extra warmth.
Breed-specific differences can be significant. For example, pet parents with short-coated dogs can learn more in our guide: Do Dobermans Get Cold?
Size and Body Condition
Small dogs tend to lose body heat faster because they have a greater surface-area-to-body-mass ratio. Thin or underweight dogs may also become cold more quickly because they have less natural insulation.
Age
Puppies may not regulate their body temperature as effectively as healthy adult dogs. Senior dogs may also be more sensitive to cold because of reduced mobility, slower metabolism, or age-related health conditions.
Health Conditions
Arthritis, joint problems, hypothyroidism, poor circulation, and other medical conditions can affect cold tolerance. Cold weather may also make stiffness and joint discomfort more noticeable in dogs with arthritis.
Dogs recovering from illness, injury, or surgery may need a warmer sleeping environment than usual. Speak with your veterinarian if you are unsure whether a health condition is affecting your dog’s ability to stay warm.
Sleeping Environment
A dog sleeping indoors on an insulated bed will usually remain warmer than a dog sleeping in a drafty room, garage, vehicle, outdoor kennel, or uninsulated shelter.
Humidity, wind, damp bedding, and contact with a cold floor can also make the environment feel colder than the temperature reading alone suggests.

Signs Your Dog Is Cold at Night
Dogs cannot tell us when they feel cold, but their behavior and body language often provide clear clues.
- Shivering or trembling: Shivering is one of the most recognizable signs that a dog is trying to generate body heat.
- Curling into a tight ball: Dogs may tuck their legs and nose close to their body to conserve warmth.
- Seeking blankets or warm spaces: A cold dog may burrow under bedding, lie near a heater, or press against a person or another pet.
- Cold ears, paws, or body: Areas with less fur may feel noticeably cooler than usual.
- Restlessness: A dog may repeatedly change sleeping positions or move around while trying to find a warmer spot.
- Whining or appearing uncomfortable: Vocalization can indicate discomfort, especially when combined with shivering or restlessness.
- Reluctance to leave a warm area: A dog may hesitate to go outside or quickly try to return indoors.
- Slowed movement or lethargy: Unusual weakness, confusion, or reduced responsiveness may indicate a more serious cold-related problem.
Persistent shivering, extreme tiredness, confusion, difficulty walking, pale gums, or slowed breathing should be treated seriously. Move the dog to a warm, dry area and contact a veterinarian promptly.
How Cold Is Too Cold for a Dog?
There is no single temperature that is safe or unsafe for every dog. A healthy, large, double-coated dog may remain comfortable in conditions that are too cold for a small, short-haired, senior, or medically vulnerable dog.
Instead of relying only on a thermostat, consider:
- Your dog’s breed and coat thickness
- Age, size, weight, and overall health
- Whether the environment is wet, windy, or drafty
- How long your dog will remain in the space
- Whether warm, dry bedding is available
- Your dog’s behavior and physical condition
If you feel uncomfortably cold in the room, your dog may also need additional warmth—particularly if they are small, short-haired, elderly, very young, or unwell.
How to Keep Your Dog Warm at Night
1. Let Your Dog Sleep Indoors
Whenever possible, allow your dog to sleep inside during cold weather. Choose a dry sleeping area away from exterior doors, open windows, air vents, and other drafts.
2. Provide Insulated Bedding
Give your dog a supportive bed that creates a barrier between their body and the floor. Add washable blankets that your dog can move under or away from as needed.
For senior dogs or dogs with arthritis, an orthopedic bed can provide both insulation and joint support.
3. Move the Bed Away From Cold Floors
Tile, concrete, and hardwood can become cold overnight. Place the dog bed on a rug, insulated mat, raised platform, or carpeted surface to reduce heat loss through the floor.
4. Use Dog Clothing When Appropriate
A properly fitted sweater or coat can help small, thin, short-haired, or senior dogs stay comfortable. Make sure the clothing is dry, allows normal movement, and does not contain loose parts that could become a choking hazard.
Remove clothing if your dog becomes too warm, begins panting, or appears uncomfortable.
5. Keep Bedding Dry
Damp bedding loses insulation and can make a dog colder. Check blankets and beds regularly, particularly in garages, outdoor shelters, vehicles, and RVs where condensation or moisture may develop.
6. Encourage Safe Evening Activity
A short indoor play session or appropriate evening walk can help your dog remain active and comfortable before bedtime. Dry your dog thoroughly if their coat or paws become wet.
7. Use Heated Pet Products Carefully
Only use heating pads or heated beds specifically designed for pets. Follow the manufacturer’s instructions and make sure your dog can move away from the heat source.
Avoid using damaged electrical products or unattended household heating pads, which may become too hot or create burn, chewing, or fire risks.
8. Monitor the Sleeping Environment
Temperatures can change considerably overnight, particularly in RVs, campers, garages, poorly insulated rooms, and homes during a power outage.
A remote temperature monitor can provide additional awareness when you are not in the same space as your dog. It should complement regular supervision and a safe heating plan rather than replace them.
Keeping Dogs Warm in an RV or Camper
RVs and campers can lose heat quickly because they generally have less insulation than permanent homes. Overnight temperatures may fall rapidly, and propane, electrical, or campground power problems can cause the heating system to stop unexpectedly.
To help protect your dog in an RV:
- Check the weather forecast before settling in for the night.
- Inspect windows, doors, vents, and slide-outs for drafts.
- Place your dog’s bed away from exterior walls and cold flooring.
- Keep extra dry blankets available.
- Confirm that the heating system is functioning properly.
- Maintain working smoke and carbon monoxide detectors.
- Never use an unsafe indoor heater or open flame for warmth.
- Monitor the interior temperature instead of relying only on the outdoor forecast.
The Waggle Pet Temperature Monitor uses cellular connectivity to help pet parents track supported environmental conditions without relying on campground Wi-Fi. It can also provide power-loss and temperature alerts, depending on the device model and active subscription.
The monitor requires adequate cellular coverage to send remote alerts. Test the device, notification settings, power connection, and cellular signal before relying on it during a trip.
When to Contact a Veterinarian
Contact a veterinarian if your dog continues shivering after being moved to a warm environment or shows signs such as:
- Extreme tiredness or weakness
- Confusion or poor coordination
- Difficulty standing or walking
- Pale gums
- Slow or shallow breathing
- Muscle stiffness
- Reduced responsiveness
- Collapse
Warm the dog gradually using dry blankets while seeking professional guidance. Avoid placing the dog directly against very hot surfaces or using intense heat, which may cause burns or other complications.
Frequently Asked Questions
Do dogs need blankets at night?
Some dogs benefit from blankets, especially small, short-haired, senior, underweight, or medically vulnerable dogs. Thick-coated dogs may not need them. Provide a blanket that your dog can move under or away from freely.
How can I tell if my dog is cold while sleeping?
Signs may include shivering, curling tightly, burrowing under blankets, restlessness, cold ears or paws, whining, or repeatedly seeking warmer sleeping spots.
Do small dogs get colder at night?
Small dogs often lose body heat more quickly than larger dogs. Many small breeds also have short or fine coats, which can make them more sensitive to cooler indoor and outdoor temperatures.
Do senior dogs feel the cold more?
Yes. Senior dogs may have reduced mobility, slower metabolism, less muscle mass, or health conditions such as arthritis that make cold nights more uncomfortable.
Can a dog sleep outside in winter?
Outdoor sleeping can expose dogs to cold, wind, moisture, and rapidly changing weather. The safest option for most companion dogs is to sleep indoors. Dogs kept outdoors require appropriate shelter, insulation, dry bedding, water, supervision, and protection suited to the specific conditions.
Should my dog wear a sweater to bed?
A sweater may help a short-haired, small, senior, or thin dog, but it must fit correctly and not restrict breathing or movement. Check your dog regularly and remove the sweater if they become hot, damp, tangled, or uncomfortable.
Can dogs get hypothermia?
Yes. Prolonged exposure to cold, wet, or windy conditions can cause a dangerous drop in body temperature. Shivering, weakness, confusion, slowed breathing, stiffness, or collapse require urgent veterinary attention.
Why does my dog curl up at night?
Dogs may curl up to conserve body heat, feel secure, or simply because the position is comfortable. If the behavior appears suddenly alongside shivering or restlessness, your dog may be cold.
Can an RV get too cold for a dog at night?
Yes. RV interiors can cool quickly because of limited insulation, drafts, changing outdoor temperatures, or heating-system failures. Monitor the interior environment and make sure your dog has warm, dry bedding and a dependable source of safe heat.
Does a pet temperature monitor replace supervision?
No. A temperature monitor can provide useful environmental alerts, but it does not replace responsible supervision, working heating equipment, regular checks, emergency planning, or veterinary care.
Final Thoughts
Dogs can get cold at night, but their level of sensitivity varies widely. Breed, coat, size, age, health, body condition, and sleeping environment all influence how well a dog tolerates cooler temperatures.
Watch for shivering, curling tightly, restlessness, cold extremities, and repeated attempts to find warmth. A dry indoor sleeping area, insulated bedding, protection from drafts, and careful environmental monitoring can help keep your dog safe and comfortable.
