Debbie Parkhurst, 45, of Calvert told the Cecil Whig she was eating an apple at her home Friday when a piece lodged in her throat. She attempted to perform the Heimlich maneuver on herself but it didn't work. After she began beating on her chest, she said Toby, her dog, noticed she was in trouble and got involved.
"The next think I know, Toby's up on his hind feet and he's got his front paws on my shoulders," she recalled. "He pushed me to the ground, and once I was on my back, he began jumping up and down on my chest."
