What are the initial steps to take if a working dog shows signs of heat stroke during outdoor operation?

• A. Move to shade and remove excess gear, cool the body with wet towels or water, provide fresh water, monitor core temperature, seek veterinary care, and transport for evaluation.
• B. Increase exercise to cool down the dog.
• C. Move to sun and continue the mission.
• D. Administer medication and wait for it to pass.

Answer: (A)

When heat stroke is suspected in a working dog, the priority is to reduce heat load quickly and start cooling while arranging veterinary care. Begin by moving the dog to shade to cut down environmental heat and remove any excess gear to lessen insulation. Start cooling immediately with cool (not ice-cold) water or damp towels over the body, and use a fan to help evaporation. Continue cooling until the core temperature is approaching about 39–39.5°C (102–103°F). Offer fresh water if the dog can drink, but don’t force fluids if the dog is vomiting or cannot swallow. If you can, monitor the core temperature with a rectal thermometer and relay the readings to the veterinary team. Seek veterinary care and arrange transport for evaluation as soon as possible, since heat stroke can cause organ damage even if outward signs improve.
