Why Does My Yorkie Burrow Under Blankets?

6 Real Reasons and How to Keep Them Safe

If you share your home with a Yorkie, you've probably lost track of them at least once, only to spot a small lump moving under the comforter.

Or maybe yours digs into the couch pillows, noses into the laundry basket, or crawls up inside your sweatshirt while you're still wearing it.

Is it normal? Usually, yes. But the reasons behind it are more interesting than you'd guess. Some go back more than 150 years, and one is happening inside your dog's brain.

Below, you'll find all six reasons, burrowing habits based on age, easy ways to turn your home into a safe and cozy burrowing playground, and one simple habit every pet parent of a tiny burrower should do.

And at the very end, there's a short list of the rare signs that mean it's time to call your vet.

What's Your Yorkie's Burrowing Style?

Every Yorkie has their own way of disappearing. See if you recognize yours, then keep reading to find out what's really behind it.

The Nose Tucker slips just their nose under the edge of the blanket and leaves the rest of their body in view. Dogs often cover their nose to warm the air they breathe, a lot like you pulling the covers over your face on a chilly morning.

The Disappearing Act leaves not even the tip of an ear in sight. Warmth or a feeling of safety could be at play, and you'll find both below.

The Lap Burrower skips the blanket and tunnels into your lap, the crook of your arm, or right up against your side. For this Yorkie, the coziest spot in the house is you, and reason #4 shows there's real science behind that.

The Laundry Diver thinks clean towels are fine, but the dirty laundry pile is the real prize. Worn clothes hold far more of your scent than freshly washed ones, which may explain why socks keep turning up in dog beds.

The Architect won't lie down until the blanket has been dug, spun, and rearranged. Dogs have scent glands in their paws, so all that digging may leave a little of their own scent behind, a quiet way of saying, "This spot is mine."

Reasons Yorkies Burrow:

#1 It's Their Terrier Instinct (Remember Smoky?)

You already know this one. Yorkies are terriers, and terriers dig.

But don't skip ahead just yet. Tucked inside the famous Smoky story is a small detail that helps explain why your Yorkie so often picks your blanket.

Yorkies were bred in 1800s England to chase rats through the cracks and crawl spaces of mills and mines. Breeders later made them much smaller, but the urge to squeeze into tight, dark places stayed.

And no Yorkie proved that better than Smoky.

During World War II, soldiers at a Philippine airfield had a problem. They needed a telegraph wire run through a pipe 70 feet long and just 8 inches wide.

So they tied a string to the 4-pound Yorkie's collar and sent her in. When she popped out the other end, they pulled the wire through with the string.

She did in minutes what would have been a dangerous three-day dig.

Now, that detail. As Smoky inched through the dark, she was following Corporal Bill Wynne's voice, calling to her from the other end.

Your Yorkie's burrowing has both of those pieces. There's the old tunneling instinct, and there's the pull toward you. That second one is a big deal, and it's coming up in reason #4.

Fun fact: The word "terrier" comes from terra, the Latin word for earth. These have always been dogs that go into the ground.

#2 A Tiny Dog Gets Cold Fast

Warmth is one of the biggest reasons Yorkies burrow.

Small bodies lose heat faster than big ones, so a 5-pound Yorkie cools off much sooner than a 70-pound Lab in the same chilly room.

On top of that, Yorkies have a single coat of silky hair with no woolly undercoat to hold in warmth. A short puppy cut means even less cover.

If your Yorkie heads under the covers more as the weather cools, here's how to help them stay warm:

• Let your own comfort be your guide. There's no official "right" temperature for a Yorkie's home. A good rule of thumb is that if you're reaching for a sweater, your Yorkie probably feels the chill too. Remember that many homes get cooler at night when the heat turns down.

• Try a light layer indoors. A Yorkie who shivers or stays buried all day may love a thin fleece pullover or other lightweight dog shirt. Pick one that's snug but not tight, with nothing to chew off, and take it off if they start to pant.

• Keep their bed off the cold floor. Tile and hardwood pull heat away from a little body. A raised bed or a thick rug underneath makes a real difference. Keep beds away from drafty doors, windows, and air conditioning vents.

• Bundle up for walks. Many vets suggest a sweater or coat for small dogs once it drops below about 45°F.

• Dry them off fast. Wet hair makes a Yorkie cold quickly. After a rainy walk or a bath, towel them well or use a hair dryer on its low setting.
  

#3 Snug Spaces Feel Safe

Wolves, the closest wild relatives of our dogs, raise their pups in dens dug into the ground. Pet dogs don't live in dens, but many still seem calmer in a small, enclosed space with something over them and a wall at their back.

Under a blanket, it's darker and quieter, and nothing can sneak up from behind.

This matters even more for a dog this small. To a Yorkie, the world is full of big feet, rolling vacuums, and visitors who move fast. A blanket gives them a spot small enough to feel in control of.

Many Yorkies do a little routine first: circling, scratching, and pushing the blanket around until it's just right. That's normal nesting behavior. They're fixing their bed exactly the way they like it.

#4 Your Blanket Smells Like You

Remember Smoky crawling toward her person's voice? Your Yorkie's version happens every day, and it runs on scent.

Does your Yorkie ignore their own bed and dive under your blanket, your pillow, or the shirt you just took off? They're picking your things on purpose.

Dogs take in the world through their noses. They have up to 300 million scent receptors, compared to about 6 million in people. To your Yorkie, your bedding is full of information, and most of it says "my person."

Researchers have even seen this in dogs' brains. A team at Emory University used MRI scans while dogs smelled different scents. The scent of a familiar person lit up a reward area of the brain more than the scent of strangers or other dogs.

So burrowing into your things can be a way to feel close to you, especially when you're out of the house. That's also why an old T-shirt in their bed can help a Yorkie who has a hard time being left alone.

#5 Hiding From Noise, Light, or Stress

Sometimes burrowing is simply a way of hiding.

Thunder, fireworks, a beeping smoke alarm, construction next door, or a house full of guests can all send a Yorkie under the covers.

Yorkies are alert little dogs that notice every sound. A blanket muffles some of it. It also blocks light, which helps if they're trying to nap in a bright room.

Gentle, steady pressure seems to calm some anxious dogs. That's the idea behind snug anxiety vests, and some research suggests they can lower heart rate in certain dogs, though they don't work for every dog. Being tucked in under a blanket may give a nervous Yorkie a similar snug feeling.

If your Yorkie only hides during storms or fireworks, letting them burrow is a kindness. Don't pull them out to "face" the noise. Give them a safe spot, stay calm yourself, and let them come out when they're ready.

If they seem stressed a lot of the time, look at what might be bothering them. Your vet can help, and so can a certified trainer or behaviorist.

#6 It's Just Plain Comfy (and Sometimes a Game)

Not every burrow has a deep reason. Blankets are soft, warm, and fun to push around, and plenty of Yorkies simply like it.

Some turn it into a game. They pop their head out, dive back under, or pounce on your hand when you wiggle it beneath the covers. For a terrier, it's a little hunting fun with no rats required.

And if you laughed or cuddled them the first time they did it, they may have learned that burrowing gets attention. Yorkies are quick studies when something pays off.

#3 Retire stringy blankets.

Loose threads and holes can snag tiny nails and teeth. Smooth fleece is a safer pick.

#4 Leave an exit at bedtime.

Tightly tucked sheets can be hard for a small dog to get out from under, so keep the end of the covers loose.

#5 Always check before you sit.

If there's one habit every owner of a tiny burrower should have, it's this one. A Yorkie under a blanket looks just like a lump of blanket, and small dogs do get sat on and stepped on this way. Pat the blanket or peek first, and teach kids and guests to do the same.

How to Give Your Yorkie a Great Burrowing Spot (and encourage them to stay warm in a doggie bed)

Since burrowing comes naturally, there's no need to stop it. The goal is to give your Yorkie a safe place to do it, ideally one that's all theirs.

These beds have a soft hood or flap your dog can crawl under, and they're made with burrowers in mind. Many Yorkies take to them right away. Look for one small enough to feel snug, so your Yorkie isn't swimming in extra space.

#1 A Covered "Cave" Bed

A small, lightweight fleece throw gives them something to dig at and arrange. Having two means one can always be in the wash.

#2 A Little of Your Scent

Tuck an old T-shirt you've worn into their bed. It costs nothing, and it can make their spot feel almost as good as yours.

#3 The Right Location

Pick a quiet spot away from drafts, blasting heat vents, and busy walkways, but not so far off that they feel left out. Most Yorkies want to be in the same room as their people.

#4 A Warm Welcome

Even with a cozy bed, their own blanket, and your T-shirt inside, some Yorkies need a little coaxing. Try warming their blanket in the dryer for a few minutes, checking that it's cozy and not hot. Hide a treat in the folds, then sit beside the bed with them for a while. Most dogs come around once their new spot feels like theirs.

Puppy vs. Senior Yorkies: How Burrowing Changes With Age

A Yorkie's love of blankets often shifts over the years. Knowing why can help you give your dog just what they need at each stage.

#1 Puppies: Born to Pile Up

For their first few weeks, newborn puppies can't control their own body temperature, so they pile together with their littermates to stay warm. That urge to snuggle into something soft often comes home with them.

Curious puppies don't stop at blankets, though. They'll squeeze behind the couch, under the bed, or into gaps behind appliances, and sometimes they get stuck. Block off tight spots like these until your puppy is older. Watch for chewing, too, since swallowed pieces of fabric can cause real trouble.

#2 Seniors: Warmth for Stiff Joints

Many older Yorkies burrow more than they used to. On top of being tiny dogs that chill easily, seniors often have stiff, achy joints that feel better with warmth, and some have a harder time staying warm than they did when they were young.

A cave bed with a low entrance lets them crawl in without jumping or climbing, and a thick, supportive cushion is easier on their joints. Keep it on the floor where they spend their day, so there are no stairs to manage.

If your senior's eyesight or hearing is fading, they may not notice you coming. Softly say their name or gently touch their shoulder before you lift the blanket, so you don't startle them awake.

Notice the opposite too. If a senior Yorkshire Terrier who always loved burrowing suddenly stops, crawling in may have started to hurt. And if they seem cold all the time, the signs in the next section are worth a look.

The Rare Times Burrowing Means Something More

In almost every case, burrowing is just a Yorkie being a Yorkie. Once in a while, though, a sudden change in hiding habits can be a dog's way of saying they don't feel well.

Call your vet if your Yorkie:

• Suddenly hides a lot when they never used to
• Hides and also won't eat, drink, or play
• Shivers even when the room is warm
• Seems weak, wobbly, or unusually sleepy
• Cries, pants, or flinches when picked up or touched
• Is losing weight, or their coat looks thin or dull

Dogs that are hurting or feeling sick often go off alone to hide.

A dog who always seems cold may have a medical reason, such as an underactive thyroid (hypothyroidism), which can make dogs sensitive to cold.

Yorkies, especially puppies, are also prone to low blood sugar (hypoglycemia). Shivering, weakness, and acting dazed are warning signs, and it can become serious quickly. If your Yorkie puppy is shaky and limp, call your vet right away.

A love of blankets on its own isn't a sign of illness. You know your dog best, and a sudden change is worth a phone call.

Quick, Last Thoughts

If you've been wondering why your Yorkie disappears under the covers, hopefully you can rest easy now. Whether they're staying warm, following an old terrier instinct, or simply snuggling into your scent, it's one of the sweetest, most natural things a Yorkie does.

Give them a cozy spot of their own, keep things safe and fun, and enjoy those little lumps moving under the blankets. After all, a Yorkie who tucks in close to you is a Yorkie who feels right at home.
