Do Dogs Get Cold at Night? Signs, Risks, and How to Keep Them Warm

You tuck yourself in under a warm blanket, but as you start to drift off, you glance at your dog curled up on the floor and wonder: do dogs get cold at night? The short answer is yes, they absolutely can. But how cold is too cold, and what can you do about it? It depends on your dog’s breed, age, health, and sleeping setup. Let’s walk through the signs that your dog is chilly, which dogs are most at risk, and practical ways to keep them warm and safe all night long.

Signs Your Dog Is Cold at Night

Dogs can’t tell us they’re cold in words, but they show it through their behavior and body language. Watch for these common signs:

• Shivering or trembling – This is the most obvious sign. If your dog is shaking even when the room isn’t freezing, they likely need warmth.
• Curling up into a tight ball – Dogs instinctively curl up to conserve body heat. If your dog is a tight little donut, they may be trying to stay warm.
• Seeking warm spots – If your dog moves to a sunny patch during the day or presses against a heater vent, they are looking for heat.
• Cold ears and paws – Touch your dog’s ears and paw pads. If they feel noticeably cold to the touch, your dog is probably cold overall.
• Whining or restlessness – Some dogs will whine, pace, or scratch at their bed if they are uncomfortable from the cold.

If you notice any of these signs, it’s time to adjust their sleeping arrangement. A simple change like adding a blanket or moving their bed away from a drafty window can make a big difference.

Which Dogs Are Most Likely to Get Cold?

Not all dogs feel the cold the same way. A thick-coated Siberian Husky might be perfectly comfortable in a chilly room, while a short-haired Chihuahua could be shivering. Here are the factors that make a dog more sensitive to cold:

• Small size and low body fat – Small breeds like Chihuahuas, Greyhounds, and French Bulldogs have less body mass to generate and retain heat.
• Thin or single-layer coats – Breeds with short, fine hair (like Boxers, Dobermans, and many terriers) lack the insulating undercoat that keeps dogs warm.
• Puppies and senior dogs – Very young and older dogs have a harder time regulating their body temperature.
• Health conditions – Dogs with arthritis, hypothyroidism, or heart disease may feel the cold more acutely.
• Certain breeds – For example, a Cane Corso has a short, dense coat and can get chilly in cooler weather, especially if they are lean. On the other hand, an Australian Shepherd has a thick double coat that offers more natural insulation, but they still need protection in extreme cold.

Knowing your dog’s breed and individual traits helps you gauge how much extra warmth they might need at night.

How Cold Is Too Cold for Dogs at Night?

There is no single number that works for every dog, but general guidelines can help. For most healthy adult dogs with medium to thick coats, temperatures above 45 degrees Fahrenheit are usually safe indoors. Once the temperature drops below 40 degrees, smaller dogs, thin-coated dogs, and seniors may start to feel uncomfortable. Below freezing (32 degrees), all dogs are at risk for hypothermia and frostbite if they are exposed for long periods without shelter or warmth.

If your dog sleeps in a crate or a room that gets drafty, check the temperature with a simple thermometer. A good rule of thumb: if you need a blanket, your dog probably does too.

Practical Ways to Keep Your Dog Warm at Night

You don’t need to buy expensive gear to help your dog sleep warmly. Here are some effective, low-cost strategies:

• Provide a cozy, insulated bed – Elevate your dog’s bed off the cold floor. A bed with raised sides or a bolster gives them a place to curl against. Add a soft blanket or a self-warming pad (no electricity needed) that reflects their body heat.
• Use dog pajamas or a sweater – For short-haired breeds or thin dogs, a snug-fitting dog sweater or pajama set can provide extra warmth while they sleep. Make sure it’s not too tight and that it doesn’t have loose parts they could chew off.
• Block drafts – Close windows near your dog’s sleeping area. Use a rolled-up towel at the bottom of a door to stop cold air from seeping in.
• Consider a heated dog bed with caution – If you use an electric heating pad or heated bed, choose one designed specifically for pets with a chew-resistant cord and automatic shut-off. Always follow the manufacturer’s instructions and supervise the first few uses.
• Let them snuggle with you (if you’re okay with it) – Sharing body heat under the covers is a natural way to keep both of you warm. Just make sure your dog can easily get off the bed if they get too hot.

For dogs that eat quickly and then feel cold, using a slow feed dog bowl for Australian Shepherds or similar breed can help them eat at a healthier pace, which may aid digestion and overall comfort. Also, providing puzzle toys for Australian Shepherds before bed can mentally tire them out, leading to deeper sleep and less restlessness that might expose them to cold drafts.

When to Worry: Hypothermia and Frostbite

While most dogs can handle a cool night indoors, extreme cold or prolonged exposure can lead to serious health issues. Hypothermia occurs when a dog’s body temperature drops below normal. Signs include intense shivering that then stops (a bad sign), lethargy, weakness, shallow breathing, and stiff muscles. Frostbite most often affects the ears, tail, and paw pads, which may appear pale, gray, or bluish and feel cold and brittle.

If you suspect your dog has hypothermia or frostbite, move them to a warm area immediately, wrap them in warm (not hot) towels, and call your veterinarian. Do not rub frostbitten areas, as this can cause tissue damage. A gentle warning: never use a hot water bottle or heating pad directly on your dog’s skin, as they can cause burns.

“A cold dog is a quiet dog, but a warm dog is a happy one. Pay attention to the small signs, and you’ll both sleep better.”

If your dog has a medical condition like arthritis or is a breed prone to cold sensitivity, talk to your vet about the best nighttime setup. For example, a high-quality diet for Australian Shepherd puppies supports healthy body condition and a thick coat, which can help with temperature regulation as they grow. Similarly, feeding a high-protein food for Cane Corsos helps maintain muscle mass and a healthy metabolism, both of which generate body heat.
