1. If there is a cane toad in your pet’s mouth, remove it, washing your hands thoroughly with soapy water afterwards.
  2. It is vital to seek immediately veterinary attention as medication is often required to counter the effects of the venom on the heart.
  3. Gently rinse the mouth out with water (using a syringe) – pointing the syringe across rather than towards the back of the mouth so the animal does not aspirate water.
  4. Using a damp cloth, wipe the mouth and gums as the venom is very sticky.
  5. If you witness your pet swallowing a cane toad, your veterinarian may instruct you to induce vomiting, however, do not induce vomiting unless instructed to.Vomiting should never be induced in an animal that is seizuring.
