A stray dog that narrowly escaped being put down is helping to save lives after Hurricane Harvey. Rocket, a lively border collie mix from Sacramento, was put on a euthanasia list in 2012, after the shelter holding the pooch deemed him too unpredictable for adoption. But National Disaster Search Dog Foundation volunteer Andrea Bergquist saw something special in Rocket's energy and saved him. Now the professionally trained canine is sniffing out storm survivors amid the wreckage in Houston. "It is truly amazing to see how far Rocket has come," Bergquist said. Christina Colizza
