VIDEOS: All in a day's work. D.C. firefighters shared photos and video of a puppy they rescued Sunday off the Long Bridge railroad tracks over the Potomac River. It's unclear how the puppy got stuck on the railroad bridge abutment, or who owns the dog. The pooch is now in custody of U.S. Park police. More photos and video from the scene show firefighters also stood by in a boat in case the dog in case it "wanted to take a swim."
