Denise Long holds her grandson, Booker West, 1, as he pets Zoey, held by Monty Long in the backyard of their home near Masonville, Colo. in July 2007. Zoey is a Chihuahua, but when a rattlesnake lunged at her owners' 1-year-old grandson, she was a real bulldog. "She got in between Booker and the snake, and that's when I heard her yipe," said Monty Long, the boy's grandfather said Thursday, July 19, 2007.
