What is Sticking Out His Tongue?

When dogs are sticking out their tongues, this generally refers to the organ, called the tongue, being frequently found sticking outside the mouth, beyond the teeth and gums.  There are several reasons why your dog is sticking out his tongue:

  • Panting
  • Hanging tongue syndrome
  • Tonguing
  • Oral cancers and other masses
  • Severe dental disease

Why Sticking Out His Tongue Occurs in Dogs

Your canine family member’s tongue is quite an interesting organ which performs many important functions for him.  Not only does it pull food and water into his mouth, but it also “smells” for him and investigates his surroundings.  Here are some reasons why your dog may be sticking out his tongue:


Panting is a cooling mechanism used by your pet.  It is defined as rapid, shallow breaths which accelerate the evaporation of water from his tongue, inside his mouth and upper respiratory tract.  The evaporation of the water aids in your dog’s ability to regulate his temperature.

Hanging Tongue Syndrome

This is a condition which is genetic in some breeds having the “smooshed” face which causes their oral cavities to be too small to accommodate the tongue.  The tongue also hangs out due to an abnormal jawbone that can’t support the tongue or due to missing teeth which create a gap through which the tongue can slip.


This is similar to the Flehmen response which is exhibited in other mammals.  This involves using the tongue to “taste the air” in a response to sniffing after a female.  Other mammals will curl the lips and raise their heads when performing this action.  

Oral Cancers and Other Masses

The tongue is prime target for oral tumors, most of which are malignant.  The tongue can also have tiny bumps or warts which are called papillomatosis, being caused by the papilloma virus which are not usually malignant.

Severe Dental Disease

Inflammation of the tongue (glossitis), inflammation of the soft mouth tissues (stomatitis) inflammation of the gums (gingivitis) and inflammation of the lips (cheilitis) can cause the tongue to stick out.  Other inflammations of the mouth and tongue can include:

  • Foreign body ingestion
  • Exposure to toxic plants or chemicals
  • Bacterial or viral infections
  • Immune -mediated diseases
  • Metabolic disease
  • Nutritional disorders

What to do if your Dog is Sticking Out His Tongue

If your dog is panting and his tongue is sticking out, this is normal.  However, if the panting being done by your pet seems excessive and there isn’t a justifiable reason for it, then an examination should be done.  You can examine your dog’s mouth to a limited degree at home but your veterinary professional can do a much more thorough examination. 

An examination by your vet is especially important if you note any growths or masses inside your pet’s mouth, or if you note any missing teeth or red and inflamed gums. These conditions will need to be treated sooner rather than later in an appropriate manner according to the conditions and diagnosis found by your vet. 

Your vet will treat infections with appropriate medications and metabolic and immune-mediated disorders and nutritional disorders with medications, supplements and dietary regimens which he deems appropriate for the condition found in your pet.  Cancers, papillomatosis, and other masses will be treated according to current medical recommendations as needed.

Prevention of Sticking Out His Tongue

There really aren’t any things that you can do if the reason your pet is sticking out his tongue is genetic.  However, if the cause is panting, you can adjust your pet’s exercise and play regimen to allow sufficient rest and appropriate temperatures to keep him from becoming overheated.  If the cause is dental disease in any stage, getting your pet’s oral health treated and maintained is the step that’s needed to prevent your dog from sticking out his tongue from that inflammation.  Being more watchful of where your pet exercises and attempting to control what he eats or investigates can prevent the inflammation from toxic plants and chemicals.  

Prevention of cancerous tumors and the papillomatosis is not something you have any control over but by keeping up with your regular and routine veterinary examinations will help to identify any suspicious lesions in your dog’s mouth.  Your at home examinations will also help to catch those masses and conditions earlier for more aggressive and appropriate treatment earlier in the process.

Cost of Sticking Out His Tongue

There are costs involved in treatment of the various reasons which are abnormal that are causing your dog’s tongue to stick out.  For example, tongue cancer treatment costs can range from $3,000 to $15,000 and treatments for the various immune deficiency disease costs can range from $1,00 to $4,000.

There are a few causes for a tongue to hang out and my be related to panting, hanging tongue syndrome (neurological injury), congenital disorders (should have presented before now) among other causes; if Kingston is having difficulty defecating he may be in pain which may cause panting and a tongue to hang. However, you should visit your Veterinarian to be on the safe side. Regards Dr Callum Turner DVM

Tongue sticks out

Hi. My pupper has started to stick out his tongue while he sleeps. It sticks out a few cms. Even when he wakes up his tongue is still out (even when he walks around the house it’s still out). It started happening a few months ago. He doesn’t do it all the time, just some of the time. I don’t know if it’s simply old age or something more. He lives a very active healthy lifestyle (walks twice daily and fresh meat)

Without seeing Silky, I can't determine why he might be doing that, but sometimes dogs will have that behavior if they have mouth pain or dental disease. It would be best to have him examined by a veterinarian, as they can look at his mouth, assess his health, and determine if he is fine, or if he needs medical attention. I hope that all goes well for him.

Tongue sticking out

My Maltese, 6 years old, has begun sticking his tongue out more than usual, especially when he is sleep. He also seems to have congestion and some wheezing, like an allergy, which has been a problem for several years. I gave him Claritin, but it does not seem to work very well, as usual. My vet checked out his mouth but he appears healthy with no sign of lost teeth, masse, infection, etc. He eats, drinks and plays normally! Also, he loves to lick everything and uses his tongue more than other dogs! I am just trying to figure out what else to do?!

Since i cannot examine Max, or see him, it is hard for me to comment on what might be going on with him. Since your veterinarian saw him, it would be a good idea to follow up with them to see what the next step might be to figure out what is happening, and if it is anything to worry about.

My dog Mauxe keeps on sticking his tongue in and out frequently and there's a minimal amount of saliva that keeps on dropping. He also does some gasping. But he only does this when he was taken for a walk outside. Is it normal? Or we have something to be concerned of?

my puppy is doing the same thing ... she seems healthy enough ...I don't know what the problem is .. will keep you posted.

Hi! My dog is walking around sticking his tongue in and out, over & over. When he does this, you can hear his tummy making a growling or popping sort of noise and he goes to the door. Once he's outside, he runs down and starts eating copious amounts of grass. Ths has been happening off and on all day today. I'm just wondering if it needs immediate attention and what you think. Thanks so much for all you do. I look forward to hearing from you & Merry Christmas!!
Oh and the weird part is that he still has an appetite.

Thank you for contacting us about Wheeler. It sounds from your description like he is nauseous, for some reason. If he is still displaying this behavior, or is vomiting, it would be a good idea to take him to your veterinarian today, partly because this may develop into more serious signs, and you don't want to have to go to the emergency over Christmas for something that could have been resolved easily! I hope that he does well.

Hi, I have dog name Runnie. He started to take his tongue out alot then normally. And he is starting to sneeze alot like if he had allergy. Is this something normal?
