🐶 12 Fascinating Dog Tongue Facts Every Pet Owner Should Know (2025 Edition) 🐾

By Dr Duncan Houston BVSc

The canine tongue is more than just a tool for slobbery kisses—it's a multifunctional organ essential to your dog's health and communication. Let's delve into 12 intriguing facts about dog tongues that every pet owner should be aware of in 2025.

1. 🐕 Dogs Pant to Cool Down

Unlike humans, dogs don't sweat through their skin. Instead, they rely on panting to regulate their body temperature. When a dog pants, moisture evaporates from their tongue, mouth, and upper respiratory tract, helping to dissipate heat and cool their body.

2. 👃 Smell Over Taste

Dogs have approximately 1,700 taste buds, significantly fewer than humans, who have around 10,000. Consequently, dogs depend more on their acute sense of smell than taste when deciding what to eat or lick. This reliance explains why they might be attracted to areas with strong scents, like our faces or feet.

3. 🌡️ Warm Tongue Indicator

A dog's normal body temperature ranges between 101.0 to 102.5°F (38.3 to 39.2°C), making their tongues feel warm to the touch. However, if your dog's tongue feels unusually hot, it could indicate a fever or overheating, and you should consult your veterinarian.

4. 🎨 Tongue Color Variations

While most dogs have pink tongues, certain breeds like the Chow Chow and Shar-Pei possess blue-black tongues. If your dog's tongue suddenly changes color to pale, blue, or purple, it may signal health issues such as oxygen deprivation or anemia, necessitating immediate veterinary attention.

5. 😌 Licking Releases Endorphins

Licking can be a self-soothing behavior for dogs. The act releases endorphins, which are natural feel-good chemicals in the brain, helping to reduce stress and promote relaxation. However, excessive licking may indicate anxiety or other underlying issues.

6. 🧼 Myth: Dog Mouths Are Cleaner Than Humans'

Contrary to popular belief, a dog's mouth isn't cleaner than a human's. Both species harbor over 600 types of bacteria in their mouths. While most are harmless, some can cause infections, especially if transmitted through bites or open wounds.

7. 🩹 Saliva and Wound Healing

Historically, dog saliva was believed to have healing properties. While it contains proteins that can inhibit infection, allowing your dog to lick wounds isn't advisable, as their saliva also contains bacteria that can lead to infections.

8. 🤧 Allergies to Dog Saliva

Some individuals are allergic to proteins found in dog saliva, leading to reactions like rashes, hives, or respiratory issues upon contact. It's essential to identify and manage such allergies appropriately.

9. 🐱 Smooth vs. Rough Tongues

Unlike cats, which have rough tongues to aid in grooming, dogs have smooth tongues. This difference is due to the presence of papillae in cats, which act like tiny hooks, whereas dogs lack these structures.

10. 👅 Macroglossia: Oversized Tongues

Macroglossia is a rare condition where a dog has an abnormally large tongue, which can interfere with eating and breathing. It's often congenital and may require medical intervention.

11. 🗣️ Communication Tool

Dogs use their tongues for more than just eating and drinking. Licking can be a form of communication, expressing affection, submission, or even signaling health issues. Observing your dog's licking behavior can provide insights into their emotional state.

12. 🧠 Neurological Indicators

Changes in tongue movement or appearance can indicate neurological problems. For instance, difficulty moving the tongue might suggest nerve damage or other neurological conditions, warranting a veterinary evaluation.
