Why do dogs sleep with their tongue out?

Dogs are very much like us in the way they sleep. I’m sure you’ve seen dogs sleeping with their tongues out before. You know what I mean: the dog is lying on its side, snoring loudly and drooling slightly onto its paws or belly. Why do dogs sleep with their tongue out? And what might this mean for your pet?

Why Do Dogs Sleep with Their Tongue Out?

Dogs with hanging tongues may also be panting and relaxing, but there are other reasons why dogs sleep with their tongue out.


Panting is a dog’s way of cooling down when the temperature is too hot. It’s also an indication that your dog may be anxious or stressed, which can lead to panting if their body temperature rises too much.

Panting doesn’t mean you should give up on your dog; it just means they feel uncomfortable or anxious. If you see this behavior in your pet, try giving them some space and reassurance (like playing with them). This will help calm their nerves and ensure they don’t overheat again in the future!

It might be a sign of heatstroke.

The tongue is a heat exchange organ. When your dog’s tongue sticks out, it could signify heatstroke. If you notice that your dog’s tongue is dry and stiff, it’s likely that he has been drinking too much or not enough water.

The tongue can act as a cooling mechanism by producing saliva, which helps keep the mouth cooler than its surroundings (which will help prevent them from overheating). However, if you see any other symptoms like swelling around the mouth or bright red coloration, call your vet immediately!

They are relaxed

Dogs are very relaxed when they sleep with their tongue out. They are comfortable, happy and not stressed out or anxious. Dogs do not have pain or anger issues when they sleep with their tongue out, so it’s safe to assume that they don’t feel like getting up anytime soon, either!

In addition, dogs usually sleep in positions that help them keep cool (like on top of you), which means the airflow coming through your body is going over them instead of against them, which could cause discomfort if there is any heat in their fur coat itself.

Hanging Tongue Syndrome

Hanging tongue syndrome is a condition in which the dog’s tongue hangs out of its mouth, even when it is not panting. It can cause serious health problems and should be treated immediately by a veterinarian.

The most common cause for hanging tongue in dogs is a short muzzle. Dogs with short muzzles may have difficulty closing their mouths completely because their tongues are often too long to fit comfortably inside them. This makes it easier for them to swallow large objects like sticks or rocks that could become lodged in their throats if they were swallowed whole rather than broken down into smaller pieces first through chewing them up into smaller pieces before eating them again!

Notice that your dog has started showing signs such as drooling excessively. This could indicate that they have picked up some bug outdoors during playtime activities inside their home environment.”


It’s important to note that dogs don’t always sleep with their tongues sticking out because they’re thirsty. Sometimes, it’s a sign of dehydration. This can be caused by a lack of water intake or heatstroke when your dog has been overexposed to the sun and is unable to sweat properly.

Dental Issues

If your dog is drooling, it could signify dental pain. Dental issues can cause drooling in dogs, especially if the condition is severe enough to cause discomfort.

Other medical problems may also cause your dog to drool: for example, he may have an infection or other health issue related to his mouth that causes pain when he eats and drinks.


Anxiety is a common cause of dogs sleeping with their tongues out. It can be caused by many things, including fear, stress and excitement. Tongue hanging can also happen in dogs who are not anxious—it’s something they do while they sleep!

So how do you tell if your dog is anxious? The best way to know for sure is by observing them closely when they’re sleeping: if the tongue seems to hang out farther than usual or droop down below their lower jaw, then this could mean that something is bothering them emotionally (such as fear).

If this happens regularly throughout the night, then it could indicate that your pet may need some extra attention from you; however, it’s important not to assume anything about what might be going on inside their mind based on these symptoms alone because sometimes other factors come into play too (like boredom).

What to do about your dog sleeping with its tongue out

If your dog is panting and has its tongue out, it may be trying to cool down. That’s normal for dogs that are hot or anxious. If the panting continues for a few days and you don’t see any other symptoms of heatstroke or heart problems, check with your vet about getting them checked out.

If your dog is dehydrated (lacks water), make sure they drink plenty before going outside again. Dehydration can cause serious health problems like seizures and brain damage if left untreated.

If there are dental issues with your pet, such as tartar buildup on their teeth or plaque buildup inside their mouth, which causes pain when eating certain foods (such as rawhide chews), talk to them about whether they should see a dentist so that they can get those cleaned up too!

Frequently Asked Questions

Why do senior dogs sleep with their tongues out?
The tongue is a muscle that can become tired, and some dogs may have dental problems. They may be dehydrated and need to drink more water. They might also be experiencing anxiety or pain because of their age or illness.

Most senior dogs will sleep with their tongues out when they sleep on their belly in what’s called cephalic position (which means facing up), but not all do this; some only do it with certain breeds such as collies or golden retrievers who are prone to snoring at night!

Why does my dog always have her tongue out?
When your dog has her tongue out, she’s doing one of two things: panting or relaxed. If your dog is panting and hot, she needs to cool down. She might be dehydrated, making her more likely to pant excessively to regulate her body temperature.

If you suspect that there’s something wrong with your dog’s dental health (or if you’re just curious about why dogs sleep with their tongues out), consult a vet for an examination before trying any home remedies. A healthy mouth can help prevent uncomfortable symptoms like gasping for breath when resting or drooling excessively at night.

What causes hanging tongue syndrome?
The cause of hanging tongue syndrome is unknown, but multiple factors are likely involved. While it’s not painful or contagious, this condition can be severe if left untreated. If your dog has been diagnosed with this condition and you want to know more about what causes it and how to treat it effectively.

The good news is that hanging tongue syndrome doesn’t affect their health in any way—it just looks funny! And while they may have some trouble eating certain foods (like ice cream), most dogs seem happy living life as an “alternative” poodle!

What does it mean when a dog’s tongue hangs out the side of its mouth?
It’s not a disease, but rather, it’s a condition. Hanging tongue syndrome is caused by a congenital disability that affects the bone structure in your dog’s jaw and neck. Dogs with hanging tongue syndrome can also have dental problems or neurological disorders.

Is hanging tongue syndrome hereditary?
While hanging tongue syndrome is not a genetic disorder, it can be caused by a brain tumor or neurological disease. These conditions are passed down from generation to generation in dogs with these traits.

Dogs that sleep with their tongues hanging out tend to have offspring who also do so this happens because of genetics. Most of the time, though, there’ll be no symptoms other than an abnormal appearance when they’re awake and alert; however, if your pet does exhibit signs such as seizures or aggression during sleep cycles (which happen during periods when we dream), then it’s best if you visit a vet immediately before any further damage occurs.


We hope you better understand why dogs sleep with their tongues out and why your dog might be doing this. While it may not seem like a big deal, it’s a symptom of something much more severe, so if you notice this behavior again or feel like your dog might be in pain, please get in touch with your veterinarian!
