Your 3-year-old Bulldog, Tank, collapsed at the dog park on a 35°C day. He's panting heavily, gums are brick-red, and he's weak. Someone has a thermometer—his rectal temp is 41.5°C. Normal is 38–39°C. Is this heatstroke?
Warning: Heatstroke is life-threatening. Core temp > 41°C causes DIC, renal failure, and cerebral edema. Brachycephalic breeds (Bulldog, Pug, Boxer) are at highest risk. Cool immediately and seek emergency care.
Move to shade. Apply cool (not ice) water to groin, armpits, paws. Use fans. Stop cooling when temp reaches 39.5°C—overcooling causes rebound hypothermia. The Triage/Emergency Specialist advises: Heatstroke—cool actively, transport to emergency. The Vital Signs Reference shows normal canine temp 38–39.2°C.
IV fluids, active cooling, monitoring for DIC and renal failure. The Emergency Drug Calculator provides drug reference. Prognosis depends on temp and duration. Brachycephalic breeds have poor heat dissipation—avoid exercise in heat.
Use Vital Signs Reference, Triage/Emergency Specialist, and Emergency Drug Calculator for heatstroke guidance.
- Temp > 41°C = heatstroke—cool immediately.
- Brachycephalic breeds are at highest risk.
- Cool water, fans—stop at 39.5°C to avoid overcooling.
- No ice baths—can cause vasoconstriction and shock.
- DIC and renal failure can develop 24–72 hours later—monitor.
