Why are snake bites so dangerous?

Venom can cause swelling, tissue destruction, bleeding problems and even paralysis. Cats and small dogs receive a proportionally larger dose. Dogs are most often bitten on the face or front legs while investigating.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Symptoms of snake-bites poisoning

  • One or two small puncture wounds, pain, swelling spreading over minutes–hours
  • Panting, restlessness, drooling
  • Weakness, shaking, wobbly walk
  • Bruising or bleeding from the wound or gums
  • Collapse, difficulty breathing, paralysis (severe)

What to do right now

  1. Keep your pet calm and still — movement spreads venom faster.
  2. Do NOT cut, suck, or apply a tourniquet. These make things worse.
  3. Remove the collar if the face/neck is swelling, and carry small pets.
  4. Get to the nearest emergency vet with antivenom; call ahead so they can prepare.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
