Why Does My Dog Sleep With His Tongue Out [3 Reasons & Solutions]

Seeing a dog with his tongue out is pretty common during the daytime. That’s why it’s pretty normal to be worried. After all, most dogs sleep with their tongues closed. 

Why does my dog sleep with his tongue out? 

The most prominent reason is the lack of teeth. Other than that, your dog probably has a longer tongue. By keeping it out, your dog can breathe more naturally. Last but not the least, your dog is probably feeling too hot and panting. 

Anyways, that was just a short answer. This matter requires further elaboration and I’m glad to do that for you. 

For now, let’s not roam around any longer and get right into it!

Dogs Sleeping With Tongues Out: 3 Reasons Why!

Dogs have several reasons to sleep with their tongues out. It can either be a syndrome or just a technique to regulate heat. 

Like dogs, other animals like cats also let their tongue out during the daytime. But overall, dogs like to do it way more than cats. 

Dogs also like to sleep on their owner’s head from time to time. 

Since there are multiple reasons I’ve decided to list them one after another. This will reduce the total time and effort needed to understand all of them.

Simply sit back, relax and go through all the points one by one. I’ve got the rest covered!

Reason 1: Your Dog Doesn’t Have All The Teeth

How old is your dog? Have you rescued your dog from the wild? These are questions that are of relevance. 

Wild dogs that you have rescued may have missing teeth. It’s pretty common and there’s nothing alarming about it. 

Some dog breeds often have their teeth pulled for health reasons. If your dog is missing some teeth, the tongue will come out! 

Because dogs can’t control their tongue while they’re sleeping or unconscious. 

This is mostly okay. Except if the tongue starts getting too dry. Dry tongues can get cracks quite easily. 

Solution: Use An Moisturizing Ointment

Dry tongues are quite easy to treat. All you need is some water to moisturize the tongue out.

But tongue moisturizers can be a good way to treat dry tongues with cracks. These ointments are extremely efficient for your dog. 

There are some other alternatives that you can use. If you have access to olive oil,  apply it to the dog’s tongue. Other than that, wet foods are also a great way to treat cracks.

It can be difficult choosing proper wet food for your dog. That’s why I’m recommending some great wet dog foods for you:

Product 1
Product 2

These foods will certainly keep your dog tongues wet. Choose whichever you like more and grab it for your dog! 

If you don’t want to do any, simply treat your dog with some wet tuna

Reason 2: Your Dog Has A Long Tongue

Yes, you’ve read that right. Some dogs have longer tongues than others. It doesn’t only depend on different dog breeds. 

Different dogs of the same breed can have tongues of different lengths. 

We’re going to hit you with a strong word now. There’s a term called “Brachycephalic”. The origin of this word is Greek. This word is used to describe animals with shorter heads.. 

Simply put, Brachycephalic animals have a head smaller than the optimal head/body ratio. Many dog breeds are Brachycephalic and Pugs are great examples. 

Dogs with a shorter head will have a bigger tongue. This is pretty self-explanatory. These dogs usually have trouble breathing because of a bigger tongue. 

That’s why they naturally tend to breathe with their mouths open. This causes their tongue to fall out and they also start doing it subconsciously while sleeping. 

Solution: Look Out for Your Dog

If that’s the case, there’s nothing else to do for you. Simply keep a lookout for your dog tongues. Make sure they aren’t too dry or cracked and it’ll be just fine. 

By the way, your dog can also have a dry mouth problem. Treating a dry mouth is different but it’s doable by yourself. 

Reason 3: Your Dog Is Feeling Hot

Have you checked your room temperature recently? Has it been really hot recently? Because dogs don’t sweat like humans or other animals. 

When dogs get really hot, they start panting. The tongue becomes a medium to let those heat out. Like tongues, they also release some heat through their cute paws.

If it’s been hot recently, your dog is probably panting in its sleep. Fortunately, there are significant differences.

Panting and breathing aren’t the same at all. Panting is heavier than breathing. It’s also much more rapid compared to normal breathing. 

Solution: Reduce the Room Temperature

Dogs can handle heat better than us. They also get way hotter due to less skin evaporation. But too much heat can cause heat strokes. 

The best way to deal with this is to reduce the room temperature. Air conditioners work just fine. You can also get a table fan for your dog and place it accordingly. 

This will cool off your dog and it’ll stop panting. 

Providing some sort of cool water is another way to do it. You can also provide it in many forms of food. 

For example, you can provide some watermelons to your dog as a refreshment.  

Other than that, you can also try cooling collars or cooling mats. They’re super effective when it comes to cooling your dog!


Question: How do you tell if your dog is having a nightmare or seizure?

Answer: Dogs love to dream! And it’s super easy to tell apart if the dream is good or not. If you see your dog kicking or twitching multiple times, it’s probably a nightmare. But dogs that have a seizure move more violently and are super rigid. 

Question: Do dogs cry in their sleep?

Answer: If your dog is crying in its sleep, it’s most likely because of dreams. Dogs can often dream of something sad and they may cry because of it. They can also bark, growl or whimper sometimes. 

Question: Why does my dog put his paws on me?

Answer: Dogs putting paws on you means they’re saying they love you. It’s a sign of affection and care. If you’re stroking your dog’s head, it’ll react by putting its paw on you!

Final Thoughts

And that’s a wrap-up on “why does my dog sleep with his tongue out”. I hope my words were able to clear some of your confusion. 

There’s also one other reason I totally forgot to mention. Dogs also sleep with their tongues out when they feel too relaxed. And that is why you also need to be relaxed and not worry too much! 

Just enjoy time with your lovely dog!
