Certain species of toads can be very poisonous to pets, including the Colorado River toad (Bufo alvarius) and the Marine toad (Bufo marinus). These toads are typically only found in certain parts of North American, including the region between Arizona and California and Florida, Texas, Hawaii, and other tropical areas (respectively). The Marine toad is considered to be more poisonous, and most dogs poisoned by these toads will die if untreated. Even just mouthing or holding the toad in the mouth can result in poisoning and death. Dogs can even be poisoned by drinking the water out of container that a toad sat in.

Poisoning is due to the bufotenines, bufagins and sterols contained within toads. Ingestion can result in severe, immediate drooling, followed by difficulty breathing, walking drunk, seizures, abnormal heart rhythms, and even death.

If you suspect your pet mouthed, licked or ingested a toad, rinse the mouth out immediately and call your veterinarian or Pet Poison Helpline for immediate life-saving advice.
