It seems a dog somehow got on an ice floe and drifted for 75 miles in the Vistula River and the Baltic sea. The dog is currently being interviewed for former owners. I'm not kidding they are letting the dog see people who claim they have lost him, the shepherd has turned down two so far by not greeting them like a lost dog should greet an owner. The dog isn't a huge dog but has a thick coat. Poland has been experiencing an exceptionally cold winter thus causing extra ice floes, even in river, the dog wandered onto an ice floe and probably cursed in doggy and said "what have I done!"
