Paws down, snout up and ready for landing; Bert, an explosive detection dog from Coast Guard Maritime Safety and Security Team Galveston, and his handler, Petty Officer 2nd Class Chandler Nuttal, approached the deck of the training boat. They hovered over it, almost effortlessly, along with a whirlwind of freezing-cold saltwater. The confidence of Nuttal and his fury friend Bert, a 5-year-old German shepherd was evident as they were lowered more than 30 feet out of a Houston-based Coast Guard rescue helicopter to the deck of the boat.
