Go to a clinic immediately if
- The pet collapses, struggles to breathe, has a seizure or becomes unresponsive
- Any neurologic change in a hot environment—confusion, staggering, seizure or altered awareness—needs immediate care
Possible signs
- Heavy panting, drooling, hot skin, vomiting, confusion or loss of coordination
- Bright-red or very pale gums, a racing heartbeat, profound weakness or collapse
What it is
Heatstroke develops when the body can no longer dissipate excess heat. Sustained high body temperature can injure the brain, kidneys, liver and clotting system, and complications may continue even if the pet appears to improve. Risk is higher in parked vehicles, hot or humid conditions, strenuous exercise, and in overweight, older or short-nosed pets.
What to expect at the veterinarian
The clinic will first assess the airway, breathing, circulation, body temperature and neurologic status. Cooling is continued in a controlled way to avoid overshooting into hypothermia. Blood and urine testing helps monitor kidney, liver, electrolyte and clotting injury; severe cases may need oxygen, intravenous fluids, treatment of complications and hospital monitoring. A single normal temperature does not rule out organ injury.
