A dog that mouths a cane toad can be poisoned in minutes. Here's how to spot them, what to do in an emergency, and how to keep them out of the yard.
Of all the nuisance wildlife in South Florida, the cane toad — also called the bufo or marine toad — is the one that turns into a genuine pet emergency. Their skin glands secrete a toxin that can poison a dog within minutes of a lick or a bite, and they're drawn to exactly where dogs are: water bowls, pool decks, and porch lights after dark. In Palm Beach County they turn up in the warm, wet months in numbers that catch a lot of new residents off guard.
None of what follows is veterinary advice, and this article can't replace a call to your vet or an emergency clinic. Think of it as what a South Florida dog owner ought to know before it's 10 p.m. and your dog is foaming on the patio.
Why they're worse here after dark and after rain
Cane toads are most active at night and after a rain, which lines up badly with the last backyard trip of the evening. They sit under porch lights waiting for the insects the light attracts, they'll drink from a dog's water bowl, and they don't run — a curious dog can mouth one before you've even seen it in the grass. Puppies and small dogs are especially at risk because it takes less toxin relative to their body weight.
The wet-season surge is real. Heavy summer rains bring them out to breed and feed, and the standing water that collects around a South Florida yard gives them everywhere to do it. That's the stretch when the emergency-vet stories pile up.
If your dog mouths a toad — act now
This is general first aid, not a substitute for a vet, and you should be heading to one while you do it. The goal is to get the toxin out of the mouth before the dog swallows more of it.
- Rinse the dog's mouth sideways with a hose or faucet, pointing the water out of the mouth — not down the throat — for several minutes.
- Wipe the gums and the roof of the mouth with a wet cloth to pull off the sticky toxin.
- Watch for bright-red gums, heavy drooling, disorientation, stumbling, or seizures — all red flags.
- Call your vet or the nearest emergency clinic and get there right away, even if the dog seems to steady.
Keeping them out of the yard
Cane toads are non-native and can be removed year-round — there's no season protecting them. Reducing them around the house comes down to taking away what draws them: food, water, and the bugs the lights pull in. Do a few of these together and you make the yard a lot less inviting.
- Bring in pet food and water bowls at night, when the toads are hunting and drinking.
- Cut back standing water — birdbaths, plant saucers, pool overflow, clogged gutters — where they breed.
- Switch off or shield the outdoor lights that pull in the insects they eat.
- Have the resident toads collected after dusk, and add low barrier fencing around pet areas if the pressure is heavy.
Questions we hear
How do I tell a cane toad from a harmless native toad?
Cane toads are large — often 4 to 6 inches or more — with big triangular glands behind the eyes and a smooth head with no ridges. Native southern toads stay small and have distinct ridges and crests on the head. When in doubt, keep pets well away and don't handle it with bare hands.
Are cane toads only out at night?
They're most active at night and after rain, especially in the warm, wet summer months — which is when the pet-emergency calls spike. You can find them during the day in damp, shaded spots, but dusk through the overnight is when the yard risk is highest.
Is the toxin dangerous to people or just dogs?
The toxin can irritate skin and is dangerous if it gets in your eyes or mouth, so wear gloves and wash up if you ever handle one — but the serious poisonings we hear about are almost always dogs that mouthed a toad. For anything beyond mild skin contact, call a doctor or poison control; we're not a medical authority.
