Last week, a team of Coast Guard marine inspectors rescued a dog that had been trapped inside a shipping container, saving it from an export voyage and an uncertain fate. As PO2 Ryan McMahon and his team were walking through a container terminal at Port of Houston, they heard barking and scratching from a container stacked high above them. They got the terminal’s longshoremen to bring the container to the ground, and when they opened it up, a shaggy dog came out through the door.
