 Saved by her big brother from a vicious dog attack in Michigan, eight-year-old Nicholas and little sister Lillian were in their grandparents' backyard in Saginaw when the pit bull next door, who had escaped before, got in. Nicholas heard Lillian scream when the dog was on her face. He jumped on the pit bull, pulled it off, kept kicking till their grandpa came running. Mama Rebecca Chitwood says bites on her six-year-old's neck came three centimeters from severing the artery.
