Heat stroke is a life-threatening state of hyperthermia (body temperature > 105°F) where the body cannot cool itself. It leads to multi-organ failure, brain swelling, and blood clotting disorders. It is most common in flat-faced (brachycephalic) breeds.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately. This is a life-threatening emergency.
Report Case / Get HelpCaused by environmental exposure (hot cars, exercise in humidity), not an infection.
Early: Excessive panting, red gums. Advanced: Collapse, vomiting, bloody diarrhea. End: Seizures, coma, cardiac arrest.
Diagnosis is based on history of heat exposure and temperature. Blood work reveals organ damage (kidney/liver) and clotting issues (DIC).
Immediate active cooling (tepid water, fans) is vital. Hospitalization for IV fluids (shock support), plasma transfusions, and oxygen is typically required.
Never leave pets in cars. Avoid exercise during peak heat. Provide shade and water. Be extra careful with Bulldogs/Pugs.
Guarded. Survival depends on how quickly temperature is normalized and if secondary organ failure occurs.
