Bufo

a genus of toads of the family Bufonidae; these amphibians carry toxins in parotid glands in their skin. Dogs or cats which mouth them are poisoned. There are a number of toxins including the cardiotoxic bufogenins, bufotoxin, bufotenins, catecholamines and serotonin. The toxicity of each species depends on the mix and concentration of toxins. Species include B. alvarius, B. canorus, B. exsul, B. ictericus, B. koynayensis, B. marinus, B. regularis, B. vulgaris.

Bufo marinus
the giant tropical toad. Introduced into many areas such as Australia and Hawaii to control insect pests. Absorption of the toxins through the oral mucosa of dogs, and less often cats, results in varying degrees of salivation, pulmonary edema, cardiac arrhythmias, cyanosis and seizures which may culminate in death of the animal.
Bufo regularis
African toad.
Bufo vulgaris
causes excess salivation and distress if caught by a dog. Called also common toad.
