Why Dogs Pout Tongues in Summer: The Science Behind It

Because dogs do not sweat and cannot stop moving due to heat, their bodies are unable to regulate temperature on their own, and they lack the ability to care for themselves and stay hydrated. Dogs' sweat glands are located entirely on their tongues, so when you see a dog panting with its tongue out, it's a clear sign that it's overheated and needs water to cool down or rest to stop active movement. Shortnosed dogs are more susceptible to heat and less efficient at dissipating it compared to longnosed dogs.

Normal body temperature for dogs should range between 37.8°C and 39°C. When the temperature reaches 40.65°C, internal organs begin to sustain damage, and a temperature of 41°C or higher is considered highly dangerous. In hot environments or during humid, oppressive weather, a dog's body system can fail and lead to death within as little as 20 minutes. Therefore, heatstroke poses the greatest threat to a dog's health during summer or any闷热 weather conditions.

Heatstroke in Pets

It's important to recognize the signs of heatstroke in pets, whether they are dogs, cats, or rabbits. If your pet exhibits rapid breathing, restlessness, excessive barking, and drooling, these are early signs of heatstroke. As the condition worsens, you may notice difficulty breathing, head tilting, or drowsiness. Without proper intervention, pets can collapse, become unconscious, and ultimately die.

Signs of Heatstroke in Dogs

Dogs suffering from heatstroke may display openmouthed panting, with a gurgling sound in their lungs, drooling, and a lack of coordination while walking. They may appear weak, disoriented, and eventually collapse, leading to death.

When a dog shows signs of heatstroke, the owner should act quickly and not wait for veterinary assistance. The most crucial step is to lower the dog's body temperature as soon as possible. Use lukewarm water (not cold water, as it can slow down skin circulation and prolong cooling) to rinse the dog's body or place the dog in a cold water bath. Then, rush the dog to a veterinary clinic immediately. Since dogs may not drink water in this state, they will need intravenous fluids and other treatments to quickly replenish fluids and administer necessary medications.
