A snake bit my dog on a walk — what are the right first moves?
Keep the dog still, carry it if you can, skip tourniquets and suction entirely, and get to a veterinary hospital immediately — movement and time are what spread venom.
Most bites land on the face or forelegs as the dog investigates. In Korea the season runs from spring through early autumn, and even a bite from a snake you cannot identify is handled the same way: calm, carry, hospital.
What helps and what harms
Helpful: keeping the dog as still as possible, carrying it to the car, keeping the bitten part below heart level if practical, removing the collar or harness near a swelling bite, and photographing the snake only from a safe distance. Harmful: tourniquets, cutting the wound, sucking venom, ice, and rubbing alcohol — each of these concentrates tissue damage or wastes minutes without slowing the venom. Swelling, oozing puncture marks, drooling, weakness, and trembling can build over the first hours.
Venom load and the body’s response vary so much between snakes and individual dogs that early mildness proves nothing about the night ahead. Treat every suspected bite as an emergency: call the nearest veterinary hospital while you drive, describe the bite site and time, and let the team decide on antivenom and monitoring.
