A frightened, shivering dog was rescued after floating at least 75 miles (120 kilometers) on an ice floe down Poland's Vistula River and into the Baltic Sea, officials said Thursday. Now his saviors just have to figure out who really owns him. So far rescuers say there's been no wagging tail of joy from the miracle dog they nicknamed “Baltic.” The thick-furred male dog was found adrift Monday 15 miles (24 kilometers) out in the Baltic Sea by the crew of the Baltica, a Polish ship of ocean scientists carrying out research. Too weak to shake off the frigid water, Baltic was dried and wrapped in blankets. After he warmed up, he was massaged, fed and soon got on his feet to seek company.
