My Dog’s Tongue is Cold: What It Means and What to Do

Have you ever noticed that your dog’s tongue feels cold sometimes? As dog owners, we often find ourselves curious about the quirks and habits of our furry companions. Understanding the reasons behind a cold tongue can help us become better caretakers and ensure our dogs’ overall well-being.

A dog’s cold tongue can be attributed to various factors, some harmless and others potentially concerning. For instance, panting allows dogs to regulate their body temperature, and the moisture on their tongue evaporates, causing it to feel cold.

However, more serious reasons might include hindered blood flow or underlying health issues. Recognizing these signs and knowing when to intervene is crucial in addressing your pet’s needs and keeping them happy and healthy.

Causes of a Cold Tongue in Dogs

A dog’s cold tongue can be caused by various factors ranging from low body temperature to exposure to a cold environment, and mouth health issues. In this section, we will discuss these primary causes in detail.

Low Body Temperature

A decreased body temperature in dogs may result in a colder tongue. Some reasons for low body temperature include:

  • Hypothyroidism: A condition where the dog’s thyroid gland is underactive, which can affect body temperature regulation.
  • Vasoconstriction: Narrowing of blood vessels, which can restrict blood flow to the tongue and make it feel colder.
  • Anemia: Low levels of oxygenated blood in the body can cause a decreased body temperature and a cold tongue sensation.
  • Licked Something Cold: While the causes of a chilly tongue listed above are concerning, it’s often that they’ve just had a drink of water or licked something cold.

We recommend calling or taking your dog to the vet if you feel the dog’s body temperature is too low. Dogs normally run a few degrees warmer than humans. A dog’s head should feel warmer than yours at all times.

Exposure to Cold Environment

A cold tongue in dogs can also be the result of exposure to a cold environment. This may happen if your dog:

  • Eats or drinks something cold, such as ice cubes or cold water.
  • Licks cold surfaces, like frosty windows or snow-covered ground.
  • Spends extended periods outdoors during winter or in air-conditioned rooms.

To prevent a cold tongue from environmental exposure, consider limiting your dog’s time in cold conditions, providing warm shelter, or offering treats and water at room temperature. Even the Great Pyrenees can only tolerate so much cold.

Mouth Health Issues

Oral health problems can also contribute to a cold tongue sensation in dogs. Some possible mouth health issues include:

  • Dry mouth syndrome: Decreased saliva production can lead to a dry and cold tongue.
  • Hypothalamic disease: Disorders affecting the hypothalamus can impact the regulation of body temperature and result in a colder tongue.
  • Medications: Some medications may cause a cold tongue sensation as a side effect.

Regular dental check-ups and cleaning can help maintain your dog’s oral health, along with monitoring for any medication side effects.

Remember to observe your dog’s physical condition and consult your veterinarian if you notice persistent cold tongue sensations or other unusual symptoms.

Signs and Symptoms to Watch


One symptom to watch for if your dog’s tongue is cold is excessive drooling. A cold tongue may be a sign of an underlying health issue which can cause an increased production of saliva. This drooling can also make your dog’s fur around their mouth appear wet or damp. Keep an eye out for any changes in your dog’s drooling habits, as this may warrant a visit to your veterinarian for a check-up.

Changes in Appetite

A cold tongue can also be linked to changes in your dog’s appetite. Some potential reasons that a dog’s appetite may change could be due to:

  • Dental problems, causing pain or difficulty in chewing
  • Gastrointestinal issues, which may lead to nausea and decreased appetite
  • Changes in your dog’s diet, resulting in a lessened interest in their food

Be observant of your dog’s eating habits, and note any significant alterations. These may signal a need for veterinary evaluation to determine the cause.

Increased Sleepiness

Another sign that may be associated with a cold tongue in dogs is increased sleepiness. It is not uncommon for dogs to exhibit lethargy or weakness when they are not feeling well, and this may manifest as sleeping more than usual. If you observe your dog sleeping more often or appearing listless, it is essential to monitor their condition closely and seek veterinary advice if the situation persists or worsens.

Seeking Veterinary Assistance

When to Visit the Vet

If your dog’s tongue is consistently cold without an apparent reason, it could be due to an underlying issue. In such cases, it is essential to seek veterinary assistance. Signs that warrant a visit to the vet include:

  • Persistent coldness: If the tongue remains cold even after ruling out environmental factors and temporary causes.Discoloration: A cold and discolored mouth could suggest a more serious medical condition.
  • Additional symptoms: If your dog exhibits other symptoms, such as lethargy, breathing difficulties, or changes in appetite or weight, it’s crucial to obtain a professional evaluation.

Potential Treatments

Upon visiting the vet, they may recommend several diagnostic tests to identify the underlying cause of your dog’s cold tongue. Some potential treatments for various possible conditions include:

  • Medications: Your vet might prescribe medications to help manage conditions such as hypothyroidism or hypothermia.
  • Fluid therapy: In cases of dehydration or hypovolemia, fluid therapy may be necessary to restore balance in your pet’s system.
  • Diet adjustments: Changing your dog’s diet can help manage some conditions, relieving symptoms or minimizing temperature regulation issues.

Remember to consult with a veterinarian if you’re unsure about your dog’s health or need guidance on addressing a cold tongue. Acting promptly will ensure that your companion receives appropriate care and enjoys optimal well-being.

Prevention and Care

Maintaining Oral Health

To ensure your dog’s overall health and prevent cold tongues, it’s essential to maintain proper oral hygiene. Regularly cleaning their teeth with a dog-safe toothpaste and toothbrush helps reduce plaque buildup and potential dental issues. Additionally, providing dental chews and toys designed to clean teeth can aid in maintaining oral health.

Regulating Temperature and Comfort

Another aspect of preventing a cold tongue in dogs is proper temperature regulation. In colder months, ensure your dog has a cozy and warm environment to rest in. During hot weather, provide a shaded area, fresh water, and avoid overexertion.

Comfort Measures

Consider the following measures to ensure your dog’s comfort, which can help prevent a cold tongue:

  • Make sure your dog always has access to fresh, room-temperature water.
  • Keep an eye on your dog’s behavior; if they seem to be excessively panting or experiencing breathing problems, consult your veterinarian.
  • Monitor your dog’s overall health, as underlying health issues may contribute to a cold tongue. Schedule regular check-ups with your veterinarian for early detection and treatment of any potential problems.
