Why Do Dogs Stick Out Their Tongues in Hot Weather?

If you’re a pet parent, you’ve likely noticed your dog panting with their tongue out during summer. But why do dogs stick out their tongues in hot weather? The answer lies in their unique biology and survival mechanisms.

Dogs Can’t Sweat Like Humans

Unlike humans, dogs don’t have sweat glands all over their bodies. Their primary sweat glands are located on their paw pads, which aren’t enough to regulate body temperature. Instead, dogs rely on their tongues to cool down. When temperatures rise, dogs stick out their tongues and pant rapidly, allowing moisture to evaporate from their tongues, mouth, and respiratory tract. This evaporation process helps release excess heat and maintain a safe body temperature.

A Dog’s Normal Body Temperature vs. Danger Zones

Dogs have a higher normal body temperature than humans—typically between 38°C to 39.2°C (100.5°F to 102.5°F). However, when their body temperature reaches 40.6°C (105°F), organs begin to suffer damage. At 41°C (106°F), the risk of fatal heatstroke skyrockets. Panting is their critical defense against overheating.

When Panting Isn’t Enough: Preventing Dog Heatstroke

Even with panting, dogs are highly vulnerable to heatstroke in hot or humid conditions. Brachycephalic breeds (e.g., Bulldogs, Pugs) and thick-coated dogs (e.g., Huskies) are especially at risk. Here’s how to protect your furry friend:

1. Provide Shade and Water: Always ensure access to fresh water and cool, shaded areas.
2. Avoid Midday Heat: Walk dogs early morning or evening when temperatures are lower.
3. Use Cooling Products: Invest in cooling mats, elevated dog beds, or portable water bowls for outdoor activities.
4. Never Leave Dogs in Cars: Even with windows cracked, car interiors can become lethal in minutes.

Emergency Steps for Dog Heatstroke

If your dog shows signs of heatstroke (excessive panting, drooling, lethargy, or collapse):

• Cool Them Immediately: Use room-temperature water—never ice-cold—to wet their body, paws, and tongue.
• Visit a Vet ASAP: Heatstroke can cause organ failure. A veterinarian can provide IV fluids and critical care.

FAQs: Why Do Dogs Pant in Summer?

Q: Do dogs sweat through their tongues?
A: No—dogs cool down by evaporating saliva from their tongues and respiratory tract during panting.

Q: How long can dogs pant safely?
A: Occasional panting is normal. However, continuous heavy panting or distress signals overheating.

Q: Can I shave my dog to keep them cool?
A: Consult a vet first. Some breeds’ coats protect against both heat and UV rays.
