If the ingestion is recent, the veterinarian operating the endoscope may be able to identify the toad and retrieve it. Some pets with toad toxicity develop low blood pressure, which can lead to kidney failure if it is prolonged. In areas where toads are common, owners should keep their pets leashed and under close supervision when outside. Toads and frogs are known to carry roundworms, tapeworms, and other parasites. This means if a dog (or cat) eats an American toad, it is not only at risk of poisoning but are toads poisonous to humans vet-approved safety facts and faq may also consume parasites and develop a parasitic infection. Do not wait for your pet to develop poisoning symptoms before you contact your vet.
- This chemical defense makes toads unpalatable or harmful, encouraging predators to release them.
- Severity depends on patient state of health, extent of exposure, length of time since exposure, and species of toad.
- More severe symptoms can include difficulty breathing, rapid heartbeat, nausea, vomiting, and even seizures.
- But they will often progress to shock and neurologic signs within 30 minutes to several hours, eventually resulting in death.
- Even if it’s not a cane or Colorado River toad, these same measures may be needed for small dogs and puppies no matter what the toad species.
Keeping pet food and water bowls indoors or cleaning them daily helps prevent toads from being attracted to the area. It is not recommended to keep poisonous toads as pets, as their toxins can pose a risk to both humans and other animals in the household. Toads are fascinating creatures that can be found in various habitats around the world. While many toads are harmless, there are some species that are poisonous and can pose a danger to humans and animals alike. In order to enjoy observing these amphibians in the wild, it is important to know how to tell if a toad is poisonous.
Interestingly, many dogs who experience toad envenomation don’t learn from the encounter and may go after a toad again, making owner vigilance crucial. If you suspect your dog has encountered a toad, acting quickly is crucial, as toad venom can rapidly progress and become life-threatening. Even if you were wearing gloves, it is still a good idea to go the extra mile by washing your hands. As earlier mentioned, American toads secrete a toxin and may carry bacteria that can be harmful, so it’s best to protect yourself. The production of bufotoxins begins with the synthesis of precursors in the liver of the toad. These precursors are then transported to the parotoid glands, where they are converted into active toxins.

Bufotoxins are potent chemicals produced by American toads and other toad species. These toxins serve as a defense mechanism to deter predators, as they can cause nausea, dizziness, and other harmful effects in potential threats. When a toad is threatened, it secretes bufotoxins through its parotoid glands, which can then be absorbed through the skin or mouth of the predator. Ingestion of true toad secretions can cause a range of symptoms, including nausea, vomiting, diarrhea, abdominal pain, and even heart arrhythmias. The initial signs will be similar to mildly toxic toads—drooling, pawing at the face, vomiting.
These bufotoxins are a type of steroidal alkaloid and can have different chemical structures depending on the species. Some common bufotoxins found in true toads include bufotenine, bufotenidine, and bufadienolides. These secretions are not venom injected through a bite or sting; instead, they release when the toad feels threatened, often under mechanical pressure from a predator’s mouth. The compounds can cause irritation to mucous membranes and various systemic effects. This chemical defense makes toads unpalatable or harmful, encouraging predators to release them. Toads, particularly the Cane Toad and the Colorado River Toad, secrete toxins that can be harmful or even deadly to dogs if ingested.
Symptoms of cane toad poisoning in humans can vary depending on the severity of exposure. More severe symptoms can include difficulty breathing, rapid heartbeat, nausea, vomiting, and even seizures. If you suspect cane toad poisoning, it is important to seek medical help immediately. Cane toads, also known as Bufo marinus, are large amphibians native to South and Central America.

Any brightly colored, rough-skinned newt or salamander likely contains TTX. Another trend is the rise in toad-related injuries among children and pets. In recent years, there have been numerous reports of children and pets becoming ill or even dying after coming into contact with poisonous toads.
Toads That Are Poisonous to Pets
- This toxin may cause irritation and general discomfort, but is not lethal to humans.
- People in certain parts of the world—China and Southeast Asia in particular—where toad secretions have been used as folk medicine and as an aphrodisiac are also at high risk.
- In the United States, the Colorado River toad (Incilius alvarius) is another species known for its toxic secretions.
- If you remove toads but do not fix the source of the problem, you’ll just have more toads later.
- A thorough physical exam, patient history, and an established veterinary-patient-client relationship is required to provide specific medical advice.
The toxins secreted by American toads are not fatal to humans, but they can cause mild to moderate irritation. The two primary compounds found in the secretions are bufotoxin and bufotenine. These substances can cause discomfort to humans, but they are generally not life-threatening. If you hadn’t thought about amphibians—frogs, newts, toads, and salamanders—you won’t forget about them after reading this article. These fascinating animals are equipped with defense mechanisms deserving are toads poisonous to humans of much caution and fear.
The Trouble with Toads: Getting to the Bottom of This Toxic Threat
To start with, it’s important to understand that not all true toads produce toxins. The ability to produce toxins is mainly found in the family Bufonidae, which includes species like the common toad (Bufo bufo) and the American toad (Anaxyrus americanus). These toads possess specialized glands known as parotoid glands, located on the back of their heads. These glands are responsible for producing and storing the toxic substances.
“During these times, toads can commonly be found in grassy yards, small dirt holes, or manmade structures like sprinkler boxes,” Wheeler said. With careful monitoring and preventive measures, the risk of a dangerous toad encounter can be significantly reduced. Dogs are naturally curious creatures, often using their noses and mouths to explore the world around them.
Are American Toads Poisonous to Humans, Dogs, or Cats?
While the symptoms are generally not life-threatening, they can cause discomfort and warrant medical attention if they persist. The Colorado River toad has an unusual mix of toxins, dominated by 5-MeO-DMT and bufotenin. If your pet licked the toad, you (or your vet) should wash out the mouth thoroughly for 5 minutes, with the hose pointed toward their nose. The veterinarian may keep the ECG on your pet for the duration of their hospitalization.
Their toxin is only harmful when ingested (such as when you pick up an American toad with your bare hands, then rub your eyes before washing your hands). While they may seem harmless and even cute to some, it’s important to consider their toxic nature. The toxin produced by true toads is a complex mixture of chemicals known as bufotoxins.
