Why Does Your Dog Sleep Under the Covers?

Dogs have all sorts of quirky behaviors that make us laugh, scratch our heads, or just want to snuggle them even more. One of the most common and endearing habits? Burrowing under the covers. If your pup has ever curled up under your blanket like a little fur burrito, you might’ve wondered why. It turns out that this cozy habit is tied back to their instincts, emotional needs, and love for their humans.

Let’s take a closer look at what’s really going on when your dog disappears under the blankets—and how you can make sure they’re safe and comfy while doing it.

Dogs and Their Need to Feel Close

Dogs are social animals by nature. Like their wolf ancestors, they thrive in close-knit groups—or in your dog’s case, your family. In the wild, sleeping close to pack members helps with warmth and protection. That need for closeness hasn’t gone away just because dogs now live in our homes.

So when your pup snuggles under the covers with you, it’s not just about staying warm—it’s about feeling safe, loved, and connected. It’s a sweet way of saying, “You’re my pack.”

Warm, Safe, and Snug: Why Dogs Love Covers

Let’s be honest: who doesn’t love a warm, comfy blanket on a chilly day? Dogs are no different. That soft, warm space under the covers can feel like the perfect safe spot to snooze.

For smaller breeds or short-haired dogs, the need for extra warmth is even stronger. They lose body heat more quickly, so the coziness of a blanket helps them regulate their temperature—and simply feel good.

It’s Instinctual, Too

There’s also a natural instinct at play. In the wild, canines would seek out sheltered, den-like spots to rest. This denning behavior made them feel hidden and protected from danger. Today, your dog might not need to hide from predators, but that instinct is still there.

Crawling under a blanket mimics the feel of a den—quiet, dark, and enclosed. That little “burrow” helps them unwind, relax, and sleep more soundly.

Trust and Bonding: Sleeping Close to You

When your dog chooses to sleep right next to you (or even on top of you!), they’re showing how much they trust you. This behavior isn’t just cute—it’s deeply rooted in their social nature. It’s their way of bonding, and sleeping close reinforces their sense of belonging in the family “pack.”

It’s also a comforting habit for them. Being near you provides emotional security, especially during times of stress or anxiety, like during thunderstorms or after a busy day.

Is It Safe for Dogs to Sleep Under the Covers?

• In most cases, yes—it’s completely safe. Dogs are quite adept at moving if they get too hot or uncomfortable. However, there are a few things to keep in mind:
• Pugs or Bulldogs can have a harder time breathing in tight, enclosed spaces.
  
• Young puppies or senior dogs may also require additional monitoring, especially if they have underlying health issues.
  
• If your dog seems restless, overheated, or has trouble breathing under the blankets, it’s best to let them sleep on top—or create a cozy den-like space for them elsewhere.

Signs Your Dog Loves Sleeping Under Covers

Not sure if your pup is a blanket burrower? Here are a few clues:

• They nudge or paw at blankets to get underneath.
  
• They try to crawl under pillows, furniture, or even laundry piles.
  
• They whine or scratch if they can’t get under the covers.

Alternatives for Dogs Who Can’t Sleep Under Covers

If your dog shouldn’t be under heavy blankets for health reasons, don’t worry—there are great alternatives to give them that cozy, den-like feel:

• Look for enclosed or cave-style dog beds that mimic the feeling of sleeping in a den.
  
• Try heated pet beds or self-warming blankets during colder months.
• Soft, plush sleeping bags for dogs are another good option—they offer warmth and a sense of security without trapping air or putting pressure on your pup.

When Sleeping Habits Change, Pay Attention

If your dog suddenly stops sleeping under the covers or starts choosing odd or hidden places to sleep, it could be a sign that something’s off. Changes in sleep behavior can sometimes be linked to stress, illness, or anxiety.

If your pup seems restless, has trouble sleeping, or acts differently, it’s worth a visit to the vet to ensure everything is okay.

Is Your Dog Crawling Under the Covers Ever Cause for Concern?

As stated by Stephanie Gibeault, MSc, CPDT in the AKC article: “Many dogs crawl under the covers every night and are perfectly safe. However, there are precautions you should take. Electric blankets aren’t a good combination with bed burrowing dogs. They can potentially be harmful if the dog scratches or digs at the blanket. Dr. Burch says it can also be a problem if the covers are too heavy or the sheets are tucked too tight, and the dog can’t get out. “This can be dangerous if the owner is a sound sleeper and does not realize there is a problem,” she adds.

You also need to consider your dog’s ability to breathe properly. “If you have ever put your own head under the blankets, you might have noticed that it is hard to get air, or you quickly get overheated. The same problem could happen to a dog,” she explains.

If your dog is crawling under the covers due to anxiety, it’s important to recognize their fear. Work with them to feel more comfortable with their surroundings, so they no longer feel the need to hide. Consider building your dog’s confidence and undertaking behavior modification techniques, like desensitization and counter conditioning. It can also be helpful to work with a professional dog trainer or animal behaviorist.”
