Leave the heat and enclosed vehicle
Move the pet to a ventilated, shaded, quiet place, stop activity and call a clinic. Flat-faced, overweight, young, senior, cardiopulmonary or thick-coated pets may deteriorate faster, but any pet can overheat; never leave one waiting in a parked car.

Escalate for breathing, awareness or circulation changes
Labored breathing, blue or pale gums, reduced responsiveness, vomiting, diarrhea, inability to stand, seizures or collapse require emergency contact. A brief reduction in panting does not prove safety; record when the pet left the heat, whether it drank and how the state changed.

Follow clinic cooling advice; avoid risky extremes
Ask the clinic for local first-aid instructions. While waiting for professional advice, keep ventilation and stop activity. Do not treat ice-water immersion, alcohol rubbing, forced water or human medicine as a universal plan; trauma, cardiopulmonary disease or toxin exposure may also be present.

Review the time, activity and environment
After care, record weather, humidity, activity length, shade, ventilation, water access, time in a car and relevant health conditions. Plan cooler activity, shade, airflow and water next time according to veterinary advice; one uneventful outing does not prove future safety.
