While most backyard encounters with frogs are harmless, some species can be poisonous to dogs. Understanding the dangers and knowing what to do if your dog comes into contact with a toad is crucial for their safety.
Toad Poisoning in Dogs: A Serious Threat
The two main culprits for toad poisoning in dogs in North America are the cane toad (also called the giant or Bufo toad) and the Colorado River toad (also known as the Sonoran Desert toad). These toads secrete toxins from their skin glands as a defense mechanism when threatened. If your dog licks or eats one, they can become very sick.
Symptoms of Frog Poisoning:
Increased salivation
Foaming at the mouth
Vocalization (whimpering, yelping)
Pawing at the face or mouth
Disorientation, stumbling, or circling
Seizures
Difficulty breathing
If you notice any of these symptoms after your dog has been around frogs, take them to the vet immediately. Early intervention is crucial for a full recovery.
Are Backyard Frogs Poisonous to Dogs?
Not all frogs are poisonous to dogs. Many common backyard frog species, such as tree frogs, are unlikely to cause serious harm. However, they can still irritate your dog's mouth and eyes if licked or ingested. Signs of this irritation may include:
Excessive drooling
Pawing at the face
Mild vomiting
If you suspect your dog has licked a frog, flush their mouth with clean water for several minutes and contact your veterinarian for further advice.
Expert Insights From Spot
Curious canines often get themselves into trouble by ingesting unexpected things. Internal data from Spot Pet Insurance reveals that the average cost of treating a dog for toxic ingestion is $662, with nearly 5,000 claims processed. This highlights the importance of keeping your dog on a leash and out of reach of potentially harmful objects, including frogs depending on the species. If you suspect your dog has ingested something poisonous, contact your veterinarian immediately.

What Happens if My Dog Eats a Frog?
The consequences of your dog eating a frog depend on the type of frog and the amount of toxin they ingested.
Poisonous Toads (cane toad, Colorado River toad): If your dog eats a poisonous toad, they can become very sick and require immediate veterinary attention. The toxins can affect their nervous system, heart, and blood vessels, leading to seizures, difficulty breathing, and even death.
Non-Poisonous Frogs (Tree Frogs): While not deadly, non-poisonous frogs can still irritate your dog's mouth and eyes. They may experience excessive drooling, pawing at the face, and mild vomiting.
Remember: When in doubt, always err on the side of caution and consult your veterinarian if you suspect your dog has ingested a frog.
Are Garden Frogs Poisonous to Dogs?
Yes, certain garden frogs can be considered poisonous to dogs. Some of the most dangerous species include cane toads and Colorado River toads. The cane toad is a particular concern in Florida. If you live in Florida, we recommend that you supervise your dog when outside to make sure they don't come into contact with a cane toad.
How To Tell If a Frog is Poisonous
One way that you can see if a frog is poisonous is to look at visual cues. Poisonous frogs are often brightly colored and have patterns. If you see a frog with these features, use caution and bring your dog inside.
Another characteristic that can give you a clue as to whether or not a frog is poisonous is the dog's behavioral traits. Certain frogs may choose not to hide during the day. This may be a sign that the frog is relying on the toxins they secrete for protection rather than camouflage.
Which Frogs are Toxic to Touch?
In the United States, several amphibian species possess toxins that can be harmful upon contact or ingestion. Some examples include the pickerel frog and the Colorado River toad. While these species have toxic secretions, negative effects typically occur through ingestion or contact with their mucous membranes rather than simply skin contact.
Why is My Dog Foaming at the Mouth After Licking a Toad?
Certain types of toads excrete toxins when threatened, and while these toxins can make a dog feel sick, the more dangerous side effects often appear only when a dog has eaten or come into contact with the mucous membrane. If your dog is foaming at the mouth after licking a toad, it is likely a reaction to the toad's toxin - you should take your pet to the vet for treatment.
How Long Does it Take for a Dog to Get Sick After Licking a Toad?
The time it takes for a dog to get sick after licking a toad can vary, but symptoms often appear within 15 to 30 minutes. If you notice any symptoms, take your pet to the vet. It's best not to wait as symptoms can worsen with time.
Key Takeaways
Enjoying the outdoors with your dog is a great way to bond, but it's important to be aware of potential dangers. By familiarizing yourself with the types of frogs in your area and keeping an eye on your dog during walks, you can help prevent accidental poisoning and keep your furry friend safe. If you have any concerns about your dog's health after encountering a frog, don't hesitate to contact your veterinarian for professional advice.
