Missing dog rescued after being buried for three days
(CNN) -- He might be an old dog, but he's a fighter. A 12-year-old German shepherd in Missouri barely survived after being buried in a sinkhole for 72 hours. The hunt for Maverick started February 4 after he wandered from his home in Parkville, north of Kansas City. "He had on his invisible fence collar," said owner Lisa Van Valkenburgh. "But that didn't stop him from walking out of bounds."
