Immediate action is necessary to save a small animal from Bufo poisoning. If your babies every contact one, and you believe that they have gotten ahold of the toxin, you MUST use the garden hose to flush out their mouth and nose right away. You'll half drown the poor thing, but you'll be saving it's life. You can do a search online for Bufo toads to find the exact method you should use with the hose. There's a technique to it, but I don't know what it is. Everyone that lives where these nasty critters live should know how to save their dog if they get poisoned. Even getting to the vet immediately isn't always going to save the dog/cat
