My Dog Licked a Toad: What To Do

Sudden, dramatic foaming at the mouth after a dog mouths a toad is the classic sign, and in some parts of the world it is a genuine emergency.

In most of the world a dog and a toad is a comedy. In Queensland, Florida, Hawaii or the Arizona desert it is an emergency, and often a fast one.

Cane toads and Colorado River toads carry potent toxin in glands on their skin and behind the head. A dog does not need to swallow one. Mouthing it is enough, because the toxin goes straight through the soft tissue of the mouth into the bloodstream. Drinking from a bowl a toad has been sitting in has done it.

What to do, in this order

1. Rinse the mouth out with running water, immediately. Tilt the head downwards so the water runs out of the mouth rather than back into the throat, and aim the flow sideways across the gums and tongue. Keep going for several seconds and wipe the gums if you can.
2. Then ring your vet or a poison line and go.

In the US, the Pet Poison Helpline or the ASPCA Animal Poison Control Center.

The rinse matters because the toxin is still sitting on the gums and being absorbed while you decide what to do. Thirty seconds of running water genuinely changes the dose.

The one way to rinse it wrong

Do not tip water down the throat of a dog that cannot hold its head up or swallow properly. That is how water ends up in the lungs, and a dog with aspiration pneumonia on top of toad toxin is in a far worse position.

The safe technique is always the same: head angled down, water directed across and out, never back and in. If your dog is too affected to hold its own head up, skip the rinse and drive.

Do not try to make your dog sick unless a vet has told you to.

What it looks like

• Sudden, dramatic drooling, usually the first thing you notice
• Brick-red gums, a distinctive and telling sign
• A dog that feels hot
• An irregular or racing heartbeat
• Difficulty breathing
• Seizures

The drooling with red gums is the combination that should have you moving. It comes on quickly, which is why the rinse and the phone call happen in the same minute rather than one after the other.

Do not talk yourself out of it

The most common reason owners delay is that the dog only had the toad in its mouth for a second and spat it straight out. That is still an exposure, and with these species it can still be a serious one. Treat mouthing exactly as you would treat swallowing.

Where and when

Cane toads and Colorado River toads are found in specific places: parts of Arizona, California, Florida, Texas, Hawaii, Australia and other tropical regions. If you are not in one of those, this is not your problem.

If you are, the risk is heavily weighted towards dawn, dusk and the hours after rain, when the toads are active and moving.

Two habits cover most of it. Bring water bowls indoors overnight rather than leaving them out for a toad to sit in, and keep your dog on a lead for the last garden trip of the evening and the first of the morning. Those two outings are when almost all of these cases happen.

Say which toad, if you can

If you saw it, say roughly how big it was and where you are. The seriously dangerous species are regional and large, and a vet in Queensland or Arizona will make a very different assessment from one in a place where the local toads are relatively harmless.

If you did not see it, say so. Nobody expects an identification.

Making the garden less interesting

Toads come for the same things everything else does: water and insects.

Bring water bowls in overnight rather than leaving them out. Turn off outside lights that pull insects in, since the insects pull the toads in after them. Keep the grass short and clear away log piles and damp hiding places near the door the dog uses. Fine mesh along the bottom of a fence keeps most of them out of a garden entirely.

And for the dogs that have learned toads are worth chasing, a lead for the last outing of the evening in the wet season is the simplest answer there is.
