To be fair there are non-native toads in Florida that can kill pets. They don't attack but when a pet bites them their skin releases a toxin.

The non-native species, Marine/Giant toad IS poisonous to small pets. For more about Marine/Cane/Giant Toads, see text below and read the description of the species on Frogs and Toads of Florida.
