The reason a dog’s tongue might feel cold is important, as it indicates the special biological characteristics that make our canine friends so unique. This blog post will examine several causes of your dog’s cold tongue while also examining the uniqueness of canine physiology and the functions of a dog’s tongue in overall health and well-being. So take a seat and continue reading as we solve the puzzle of your dog’s nice greeting.

Why Is My Dog's Tongue Cold

Role of the dog’s tongue in thermoregulation

Dogs use their tongues for many things, for example, digesting food and spotting tastes, drinking water, and even barking to communicate. However, keeping the body at an accurate temperature is one of its most important jobs. Dogs don’t sweat the same way as humans; thus, they require different cooling mechanisms. Canines rely on their tongues and panting as the major way of thermoregulation.

Tongue Anatomy

A dog’s tongue is made up of a set of muscles called lingual muscles that permit flexibility and motion. In order to ingest food and water more effectively, these allow dogs to orient their muzzles in different directions. The papillae, which are microscopic bumps that cover the organ and are useful for grooming fur, further enhance this rough texture. Furthermore, numerous blood vessels are close to the surface, rendering it highly vascularized. During panting, therefore, blood flows near its surface, allowing efficient heat exchange and cooling.

Normal vs. Abnormal Tongue Temperature in Dogs

One of the correct methods to gauge your dog’s general health is to learn their tongue temperature. Let’s explore the difference:

Normal Tongue Temperature

Dogs have a natural ability to control their body temperature. A healthy dog’s tongue will usually feel slightly cold to the touch because panting is their natural cooling mechanism. But the definition of “normal” might change depending on the dog in question, their activity level, their surroundings, and even their breed. With few exceptions, a cool tongue for a quiet dog that is not active, will range within normal limits. If the dog is healthy, happy and active its temperature should be in the range of 100.5-102.5 degrees Fahrenheit or 38-39.2°C . However, always keep an eye on any changes in behavior or physical state and consult a vet if you’re concerned about anything.

Abnormal Tongue Temperature

Conversely, hypothermia, or a decrease in body temperature, may be indicated in dogs through cold tongues. Frost bites for long durations, and poor thermoregulation within a dog can bring forth these conditions. Furthermore, a hot or warm tongue in your dog could also suggest the presence of fever, thirstiness, heat exhaustion, open wounds, and irritations. Therefore, it is important to monitor the body temperature of your dog closely; if it does not increase to normal, then take your dog immediately to the veterinary office.

Is it Bad That My Dog’s Tongue is Cold?

A cold tongue on a dog is usually nothing to worry about—it means the dog is able to keep its body temperature stable. It is possible for a cold tongue to be a sign of a problem sometimes, though. If your dog has a cold tongue and other symptoms like feeling tired, changing the way he eats or drinks, or breathing a lot, this could be a sign of a deeper health problem. In addition, if your dog’s tongue feels cold when you touch it in a cool place, it could mean his blood flow is poor or he has another heart problem. Always pay attention to the situation and any other signs your dog may show. If you are concerned about your pet’s wellbeing or observe significant modifications in their thermoregulation, consult your veterinarian.

12 Reasons Why My Dog’s Tongue Is Cold?

We now know that a dog’s tongue can feel cold because of the way their bodies naturally cool themselves. Let us explore some causes of a cold tongue in dogs.


Instead of sweating like humans do when they feel hot, dogs pant, hence reducing their body temperatures this way. Saliva evaporates over the tongue during this process, causing cool blood to circulate through the mouth. The cool blood then flows back to the dog’s heart, where it lowers its body temperature. It’s a very effective method for helping dogs regulate their body temperature when exercising or in hot weather, keeping their internal systems running at a safe temperature.

Recent Meal

When a dog eats or chews something cold, like ice chips or dog-safe frozen treats, it can temporarily cool down its tongue. This is similar to what happens when people take icy drinks or popsicles and sometimes experience a momentary chill on their palates after eating them. In dogs, the consumption of cold items can result in a noticeable drop in tongue temperature due to the direct transfer of cold to the tongue’s tissue. While this is generally harmless, and the tongue should return to its normal temperature shortly, continuous or frequent consumption of extremely cold items should be monitored as it could lead to discomfort or more serious issues like tooth sensitivity or gastrointestinal upset.

Drinking cold water

Dogs also drink water to regulate their body temperature; sometimes, it can be quite cold. The cool water they consume directly cools the tongue and blood vessels close to its surface. This then lowers the overall body temperature as well. In another case, you may notice that after a long walk or exercise session, your dog goes straight to their water bowl for a drink. This behavior is not only due to thirst but also to cooling off.


You might not believe it, but the type of your dog can affect how hot its tongue is. Because of their genes, some dogs may have naturally cold mouths. Siberian Huskies and Malamutes are some breeds of dogs which have tongues that feel colder than others because they have two coats to keep them warm when it gets cold. This makes them sweat less, and their tongues feel colder. Because of the way their bodies are built, these breeds naturally have lips that are colder.

They Were Licking Something Cold

At times, the dog’s tongue may be cold because it licks something cold such as an ice cube, frozen toy, frozen food, ice cream or even a cold surface. Dogs also love to explore their environment with their mouth although during rainy seasons having a walk with your dog makes their tongue feel more colder than normal. The same goes for winter weather; licking snow or ice may result in a cold tongue. Unless it is present along with additional illness symptoms, there is no cause for concern.


Another conceivable cause of a dog’s cold tongue is vasoconstriction. Vasoconstriction means the narrowing of blood vessels, which restricts blood flow to the surface of the skin. When it gets colder or it is stressed and tensed, a dog’s body, in its bid to save heat and keep up with body temperature, pulls away from their tongue by constricting vessels as part of the ‘fight or flight’ response. Such conditions can make you notice that your pet’s tongue is much colder than normal.

They’re Under Stress

Stress or anxiety could also lead to vasoconstriction in dogs, resulting in cold tongues. This is because stress causes a “fight-or-flight” reaction that diverts blood away from unessential places like the mouth to where it’s most needed—the heart and lungs, for instance. If your dog has experienced a stressful event recently or appears particularly anxious, their cool tongue could indicate their bodies are reacting to this situation.


In other cases, a cold tongue may be indicative of dehydration. Dogs face challenges when trying to regulate their own body temperatures during periods of dehydration, especially if they are exposed to hot weather or have just finished running around doing intense exercises. Other signs include tiredness and no appetite at all. In case you think your dog may be dried out, offer it some water and monitor its drinking habits closely. If you are worried about your dog’s level of hydration, speak with a vet.

Environmental Factors

The temperature of your dog’s tongue may also depend on its environment. If it is lying on a cool surface or in shaded areas, the tongue would be cold because heat from their bodies had been lost to these objects near them. In a similar manner, if they have been subjected to extreme temperatures, like staying outside for a long time during hot or cold weather, their tongues will be colder if the body uses homeostatic mechanisms to release heat as a means of cooling itself down in an extremely hot environment. It is normal for your dog’s tongue temperature to vary depending on where he or she is.

Unusual Sleeping Positions

Sometimes, a dog’s sleeping habits make his or her tongue feel cold. For example, gravity can play a part here; it makes it hard for warm blood to reach the tongue in case the dog likes sleeping with its belly up and back down on the ground. When dogs faces point up and away from the ground, blood moves towards the lower parts of the body, making tongues cooler than usual. What you should note, though, is that this is normal and usually doesn’t indicate any health problems. A cool tongue while napping could just mean that if your dog keeps his or her tongue warm enough during their waking hours, then nothing much might be wrong.

Underlying Health Conditions

Some other cases may show that a cold tongue is not normal, and sometimes, it may indicate an underlying health issue. This can result from conditions such as hypothyroidism, diabetes or Addison’s disease among other illnesses which impair the regulation of body temperatures by dogs. If your pet’s tongue is consistently colder than usual while exhibiting the symptoms listed above, you should consider what is wrong with it, such as a change in habits or refusal to accept food. It is good, however, to take your animal to a veterinary doctor for examination and diagnosis, where necessary.


A dog’s age can also have an effect on the temperature of their tongues. In older dogs, the metabolic rate slows down, and they don’t have much movement involved in their body functions, so they might find it hard to maintain proper body temperature, leading them to have a cooler mouth, such as increased sleeping time or less active periods. However, you should check your senior dog’s overall health and speak with a veterinarian if you observe any unusual changes in their tongue temperature.

What to Do About My Dog Having a Cold Tongue

  • Observe and Record: Keep a log of when your dog’s tongue feels cold, and note any accompanying symptoms or behaviors. This can help identify patterns or triggers.
  • Assess the environment: Check if the dog’s surroundings contribute to a colder tongue, such as lying on cold surfaces or recent weather changes.
  • Evaluate Diet and Hydration: Ensure your dog has access to fresh water at all times and assess if they’ve ingested cold food or treats that could temporarily lower tongue temperature.
  • Monitor Stress Levels: Observe your dog for signs of anxiety or stress, which may call for changing its environment or routine so that it can relax.
  • Check for Signs of Dehydration: Look out for other symptoms of dehydration in your dog and provide plenty of water to drink. If unsure, talk to your veterinarian.
  • Consult your veterinarian: To rule out any underlying medical conditions, make an appointment to see your veterinarian if you have a persistent cold tongue or other concerning symptoms.
  • Consider Your Dog’s Age: Keep in mind that older dogs may have naturally cooler tongues, though it’s important to observe any other potential signs of age-related issues.
  • Offer Comfort: If your dog seems comfortable and there are no concerning health changes, provide them with a warm and cozy space, especially during the colder months.


To sum up, several things can cause a cold tongue in dogs, including stress, environmental conditions, diet and hydration, age, and sleeping positions. It’s generally not a big deal, but it’s important to watch your dog’s health as well as its actions for other symptoms that are worrying. Seek the advice of the veterinarian if you have any worries or if there are changes in your dog’s tongue temperature that persist. Generally speaking, this is just another weird thing about our four-legged friends and does not count for anything serious most of the time. So watch out for their tongues’ temperature, but also consider ensuring their general good health. Show them plenty of love and care, and they’ll give you a happy lick in return.
