What kind of first aid measures should be taken in case of heat stress?

The appropriate first aid measure in cases of heat stress involves using ice packs and maintaining a calm environment. Applying ice packs to areas such as the groin, armpits, and neck can effectively lower the dog's body temperature. Keeping calm is crucial, as stress can exacerbate the situation, making it more difficult for the dog to recover. It's important to focus on gradual cooling rather than inducing shock to the system, which can happen if a dog is encouraged to run or is exposed to sudden extreme temperature changes.

Using water directly on the dog may help in cooling, but it can also be less controlled than using ice packs, which target heat effectively at specific body points. Lastly, providing food with electrolytes is not a priority in an acute situation of heat stress; instead, immediate cooling measures should come first to prevent further complications.
