ALBANY, N.Y. — An online petition drive is under way to reunite a former Marine corporal with the combat dog she was injured with in Iraq. U.S. Sen. Charles Schumer says Cpl. Megan Leavey of Rockland County was injured along with military dog Rex while trying to disarm an explosive in Iraq in 2006. Leavey earned a Purple Heart and a Combat Valor Medal and spent a year recovering with Rex.
