Japanese Barking Frogs?

Web Producer: Kerry Corum

You've heard people say that a dog's bark is worse than his bite, but what about a frog's bark?

Scientist in Japan have discovered an unusual frog that doesn't "croak", but instead barks like a dog.

The barking frog was discovered in central Japan. Scientist are unsure why the frog sounds so different that other types of frogs, but say the unusual sound is used to attract mates.

No word yet, if the frog can fetch as well.
