The summer season continuing in the Northern Hemisphere has faced Europe and the United States with an unusual and dangerous heat wave. These extreme temperatures not only create a challenging situation for humans but also pose serious risks to the health and safety of pets. Especially our four-legged friends, dogs, perceive and experience temperature in a very different way than humans due to their body structure. While humans can regulate their body temperature through sweating, dogs have a much more limited thermoregulation mechanism, relying largely on mouth breathing and the few areas where their collars are located. Therefore, there is always the possibility of unknowingly putting them into life-threatening heat stress without the owner realizing the danger.
Heat stress or heat stroke in dogs poses a life-threatening danger and symptoms can progress rapidly. Initially, excessive panting during non-excessive exercise, excessive drooling, and restlessness may be seen, but as the condition worsens, symptoms such as rapid pulse, difficulty breathing, weakness, and vomiting appear. It should not only be considered that dogs struggle to maintain their body temperature, but also thermal burns occurring while walking on hot floors. Asphalt and concrete surfaces can heat up much more than the air temperature due to the sun's effect and can cause serious damage to the animal's sensitive paw pads. Under these conditions, while it may seem like a suitable walking environment for humans with their shoes, the ground temperature for dogs may have reached an unbearable level.
Experts and veterinarians recommend the 'five-second rule' as a simple but effective way to test whether the temperature is dangerous. According to this rule, press the back of your hand or palm against the ground for five seconds before taking your dog out; if the ground feels too hot for you or you cannot tolerate it within this time, the ground is definitely too hot for your dog's bare paws. This method provides a reliable reference point for understanding the thermal condition of the ground, independent of the outdoor temperature. Looking only at the air temperature can be misleading, because ground surfaces exposed to the sun can reach temperatures tens of degrees higher than the air temperature, making walking impossible.
Planning safe walking times is one of the most basic strategies pet owners should follow during hot summer months. Walks should be avoided during the hours when the sun's rays are steepest and the temperature peaks, usually in the afternoon and early evening. Instead, very early morning hours when the ground and air are cooler, or evening hours after sunset should be preferred. Also, the walk duration should be kept as short as possible, the dog should be prevented from staying constantly in the sun, and clean, cool water should definitely be given during breaks. The dog's fur structure, age, and weight are also factors affecting heat tolerance, so each animal's endurance to heat may vary; therefore, their behavior needs to be monitored carefully.
In conclusion, extreme heat events increasing on a global scale are redefining the responsibilities of pet ownership. The physiological limitations of dogs debunk the idea that they can adapt to human activities in all conditions and force owners to show vital care. The best approach for their welfare is to cancel the walk if there is any doubt, or to minimize the duration even if no vital risk is seen. Under these challenging conditions brought by climate change, protecting our loyal friends depends on keeping them away from heat stress and thirst in a cool and safe environment, and avoiding hot grounds that are much harsher than we perceive.
