Signs to Look Out For

June 5, 2025

Toads are a common and for the most part harmless feature of backyards around the world – however a certain number of species are equipped with natural defence systems against predators that can backfire for curious dogs who cross their path. Equipped with poisonous skin of various strengths, a dog who licks or happens to eat a toxic toad may be in serious trouble.

In the US, the Colorado River Toad and Giant Toad are the two most likely species to cause illness and death in dogs. In Australia, the introduced Cane Toad is a prevalent and serious problem for pet owners as its range extends across half the continent and lethal results are likely in untreated cases.

Signs of Poisoning

There are a number of signs of poisoning that may be apparent in your dog. Excessive drooping, frothy salivation, head shaking, pawing at the mouth and vomiting are common symptoms, with severity varying depending on the type of toad, the amount of toxin the dog was exposed to and the amount of time that passed before they were found by their owners. Other symptoms are cardiac arrhythmias, dyspnea (shortness of breath), cyanosis (blueish discolouration of skin) and seizures.

Treatment

If you suspect your dog has had a nasty encounter with a toad an immediate trip to the vet is essential. Time is one of the most crucial factors which will determine whether or not a dog will survive. An affected dog will likely have their mouth flushed and drugs used to control abnormal heart rhythms. A cool bath may also be used to reduce temperature and painkillers administered to reduce the dog’s suffering whilst it stabilises.

Remember

Whilst toads can be dangerous to dogs it is important not to overreact if you see a toad or frog in your garden as they are an important part of the ecosystem that are often completely harmless to your pet. Your local wildlife authority is the best source of information as to what species are in your area and if any are potentially harmful to your four-legged friend.
