I think bullfrogs are poisonous.they can harm anyone.based from my experience huh!they killed my puppy!!!!!!!!?

Though most toads are bitter tasting and usually result in profuse drooling in any pet that tries to take a taste, only a couple of species of toads are truly poisonous. The poisonous secretions from these toads can affect animals who come in contact with them, causing a host of clinical signs.
