Symptoms of Bufo Toad Poisoning in a Dog

Toads are plentiful and can pose a health hazard to dogs that may ingest them. Bufo toads are most commonly found in Florida and South Texas and are poisonous to dogs. Dogs that bite, lick or pick up Bufo toads may experience adverse health effects and may require immediate medical attention. Small dogs may be at a higher risk of death from toad poisoning than larger dogs.



Dogs that have been poisoned by the Bufo toad, will need immediate medical attention. There is no antidote for the toxins in the Bufo toad and veterinary treatment consists of supportive care, such as IV fluids and anti-arrhythmic drugs.

  1. Mouth Pain

    • Dogs who have been poisoned by the Bufo toad may exhibit symptoms of pain in the mouth. Drooling, foaming at the mouth and shaking the head may be the first symptoms the dog has come into contact with a toad. Toads can leave a slimy substance that can cause mouth pain once the dog has bitten the toad. Dog owners should check the inside of the dog's mouth, looking for red, swollen gums. Rinsing the dog's mouth with water and rubbing the gums may help soothe the pain in the mouth of the dog.

    Stomach Upset

    • Vomiting, diarrhea and retching are symptoms of poisoning in dogs by the Bufo toad. Dogs may also experience generalized weakness and do not move around much. Dogs that have been poisoned by the Bufo toad may become extremely sick. Terriers have been poisoned most often by Bufo toads and many of them die as a result. According to the University of Florida IFAS Extension's website, terriers have a natural inclination to hunt and attack smaller animals, making them more susceptible to toad poisoning than other breeds.

    Neurological Symptoms

    • Toad poisoning may produce neurological symptoms in dogs. Dogs often shake their head excessively, whimper and experience a loss of coordination, making it difficult to walk or stand. Serious cases of Bufo toad poisoning may lead to seizures, which can be fatal.

    Cardiovascular Symptoms

    • Dogs may experience serious cardiovascular symptoms following toad exposure and poisoning. Toxins on the toad can affect the dog's heart rate and can cause an irregular heartbeat. Dogs may also have a fever greater than 105 degrees F, which is known as hyperthermia.
