ECOVIEWS: Why do dogs that eat toads foam at the mouth? The Tuscaloosa News © J.D.

I have received a version of the following question from people in several states, most recently Alabama, South Carolina and Tennessee.
Q. We see or hear various frogs and toads in our neighborhood almost year round. This summer, our dog has managed to lick a couple and immediately started foaming at the mouth and shaking his head. The next day he did the same thing, as if he had not learned a lesson. Are there any particular species we need to be vigilant about avoiding for our dog s health? I have heard of a toad in Florida that can kill a dog.
ECOVIEWS: That snake in the yard might actually be a legless lizard The Tuscaloosa News © Parker Gibbons The eastern glass lizard, which has no legs, looks like a snake but has ear openings and can blink its eyes. [Photo courtesy Parker Gibbons]
Q. We found a snake in our yard in Charleston, South Carolina, but have been unable to identify it from pictures in a field guide or on the web. Is it an exotic species?
A. I get this query every year and send the same response: “Great find. Actually, what you found was not a snake, but one of the legless lizards or glass lizards.” Unlike snakes, they have eyelids that can blink and ear openings. Unlike most lizards they have no legs. They are sometimes called glass snakes because of their obvious resemblance to a snake.
