The NATURE mini-series "Pets: Wild at Heart" shows how our pets' innate abilities and behaviors are rooted in their wild ancestry. Does your normally loving and well-behaved pet sometimes remind you of a wild animal? Submit your photo of your pet in their wildest pose! A few select submissions will be shared with NATURE's 250,000+ Facebook fans.

Don’t let this cute little chubby face fool ya – if you are a chipmunk, squirrel, bird or even a big, slobbering neighborhood dog, Beep Beep here is going to give you the ol’ “what fer” with her roaring voice and/or her needle sharp teeth. She may only weigh 15 lbs., but around our house she’s known as “The Baby-Faced Assassin”.
