Why Do Chihuahuas Like to Sleep Under the Covers?

Chihuahuas are not the only breed of dog that enjoys burrowing under blankets, but they are one of the most well-known for this behavior. Chihuahuas burrow for many reasons such as to stay warm or to hide, for a sense of security, or due to a health issue.

Chihuahuas are known for enjoying cozy spots, and what could be more comfortable than a pile of soft blankets?

1. To Stay Warm

Chihuahuas come from Mexico which has a warm climate so they tend to burrow in order to retain heat.

They are not well suited to cold weather due to their high metabolism and thinner coat. This is why Chihuahuas should not be outdoor dogs, especially in cold climates.

One of the main reasons why your Chihuahua enjoys burrowing under the covers or blankets is because they are trying to keep themselves warm by creating a cozy nest.

This gives them a layer of protection from chilly air, and the extra warmth helps them to maintain their body temperature. Chihuahuas will start shivering when the temperature is around 60 degrees Fahrenheit or below.

Chihuahuas have a knack for finding the warmest spot in the room, which is often in between your legs or under the blankets. They also love sunbathing to warm up.

During the winter, our Chihuahua loves sleeping under the covers of our bed at night. He burrows his way in and ends up taking up a good part of the bed!

Next time you can’t find your Chihuahua in your house, be sure to check under all the blankets and even piles of clothes, especially if they just came out of the dryer.

2. To Feel Safe

Sleeping under the covers can provide a sense of security for your Chihuahua.

If your dog curls up under the covers near you, that means they feel secure and trust you.

They might even begin snoring!

When buried under a pile of blankets, dogs feel hidden and safe from any potential threats like a form of cozy camouflage.

Chihuahuas can get startled and scared easily, so this behavior may also be a way for them to cope.

If there is a loud noise outside or something that scares them, they may seek refuge under the safety of the covers.

This instinct is especially strong in small breeds like Chihuahuas, who may naturally feel vulnerable due to their size.

3. It’s Comfy

Why do Chihuahuas sleep under blankets? 

Dogs are known for enjoying cozy spots, and what could be more comfortable than a pile of blankets?

Doubly so when they are fresh from the warm dryer.

This is likely one of the reasons why your Chihuahua enjoys sleeping under the covers.

Provide your Chihuahuas with some soft blankets like fleece or flannel to take their sleeping experience to the next level.

Blankets aren’t the only thing that your Chihuahua may burrow under.

You might even find your Chihuahua in unusual spots like under the clothes in laundry baskets or inside backpacks or suitcases.

They will find any little space to curl up in!

We often find our Chihuahua snuggled up under a blanket on the couch, so we have to make sure we check before we sit down or we might get a surprise.

Just be sure that the blankets are not too heavy or bulky, as this can make it difficult for your Chihuahua to move around.

4. Illness or Injury

Another reason why Chihuahuas burrow under the covers is because they could be sick or hurt.

Dogs tend to hide based on instinct when they are feeling ill or injured.

A blanket makes a great place for a Chihuahua to hide if they are feeling under the weather.

There are lots of reasons why Chihuahuas sleep so much, but if your Chihuahua suddenly starts sleeping under the covers more often than usual, this could be a sign of illness or injury.

If you notice this change in behavior, take your dog to the vet for a check-up and be sure to give them lots of boo boo kisses.

5. Anxiety or Fear

Why do Chihuahuas burrow under covers? Well, it could be due to anxiety.

Chihuahuas tend to be clingy dogs that love following their owners around.

They were bred to be companions. As a result, they may experience separation anxiety when left alone.

Other causes of anxiety include fear, aging, and past trauma.

Chihuahuas can be afraid of loud noises, certain people, other dogs, balloons, car rides, flies, brooms, etc., which can trigger their anxiety.

Older dogs may suffer from anxiety due to cognitive decline.

Burrowing into a nest of blankets can provide a feeling of comfort and the small space can help ease their fears. You can try out a weighted dog blanket for a calming effect.

Another option is a hooded burrowing cave bed or soft tent to help your Chihuahua feel more secure.

This burrowing donut bed comes with an attached blanket and mimics the feeling of being in a den, which can help to alleviate anxiety and promote relaxation.

It’s an excellent choice for a Chihuahua burrow bed!

6. To Hide From Noises or People

Why do Chihuahuas burrow under blankets?

Well, if your Chihuahua is afraid of loud noises or strangers, then burrowing under blankets can help to muffle the sound and make them feel hidden.

When your Chihuahua exhibits this behavior, it’s important to help them feel secure in their environment and not force them out from under the blankets.

If you’re having a lot of people over or there is construction happening near your home, try to provide a quiet, safe space for your Chihuahua to retreat to.

This could be a crate or dog pen filled with cozy blankets and some of their favorite toys like a stuffed Kong or a lick mat.

This confined space will keep your Chihuahua away from the noise and strangers and help your Chihuahua feel safe.

7. To Make a Den

Another reason why your Chihuahua sleeps under the covers is to make a den.

Dogs are denning animals and natural-born diggers, so burrowing under the covers gives them a chance to live out this instinct.

Denning animals feel safe and secure in small, enclosed spaces.

A den is where they go to sleep, relax, and feel protected, especially if they are ill.

Before, during, and after whelping, mothers will often take refuge in a den.

Puppies spend their first few weeks in a den snuggled up with their mother and littermates.

By sleeping under the covers, your Chihuahua is fulfilling their instinctual need to make a den.

If your dog is digging under the covers to make a den, provide them with a small, cozy space of their own, like a crate or dog bed with blankets, to help satisfy this instinct.

8. Trait From Puppyhood

Why do Chihuahuas sleep under covers? Because puppies are born with a natural instinct to burrow.

This behavior is often seen in littermates who will snuggle together and up against their mother for warmth and security.

Dogs are also denning animals, meaning they like to sleep in small, enclosed spaces.

This instinct is strong in puppies and can carry into adulthood.

For dogs like Chihuahuas, this behavior usually persists into adulthood, and they will continue to seek out cozy spots to sleep in.

9. Pregnancy

Why do Chihuahuas burrow? If your intact female Chihuahua is burrowing, this could be a sign she is pregnant and looking for a place to give birth.

During pregnancy, your dog’s nesting instinct will kick in and she will start looking for a safe, enclosed space to have her puppies.

She might also develop floppy ears while pregnant, which will resolve after giving birth.

If you think your Chihuahua is pregnant, take her to the vet for a check-up.

They will be able to confirm the pregnancy and give you guidance on how to care for your pregnant dog.

Provide your pregnant Chihuahua with a comfortable, safe place to nest, like a crate or donut dog bed with blankets.

10. False Pregnancy

Female dogs can experience false pregnancy, or pseudopregnancy, which is when they show signs of pregnancy but are not actually pregnant.

A dog’s body thinks she is pregnant and her maternal instincts will kick in

Typically, this occurs 4-9 weeks after the last heat cycle.

Signs of false pregnancy include nesting behavior, like burrowing into blankets, as well as collecting and guarding objects.

Physical signs of false pregnancy include:

  • weight gain
  • milk production
  • enlargement of mammary glands
  • loss of appetite
  • fluid retention
  • lethargy

If you think your Chihuahua is experiencing a false pregnancy, take her to the vet for a check-up.

Is It Safe For Chihuahuas to Sleep Under the Covers?

Generally, it is safe for Chihuahuas to sleep under the covers.

You might worry that your Chi will suffocate or overheat, but dogs are pretty good at regulating their body temperature.

If they get too warm underneath, they will simply come out for air.

Our Chihuahua knows when to pop out of the covers even when it’s the middle of the night. The gamble is whether he comes out face first or butt first.

The only time you might not want your Chihuahua to sleep under the covers is if they are pregnant or have a health condition that makes it difficult to regulate their body temperature.

There are a few things to keep in mind if you let your Chihuahua sleep in your bed.

You should stay away from heavy weighted blankets, as these could make it harder for your dog to move around and breathe (looking at you, Mexican tiger blankets).

Stick to lighter, breathable fabrics.

Using a heated electric blanket is probably not a good idea either, as this could cause your dog to overheat.

Should You Let Your Chihuahua Sleep in Your Bed?

Another reason is they could simply be trying to find a place to bury their favorite toy! Dogs have a natural instinct to bury things, and your Chi might be trying to hide their toy.
