File this one under the heading, "there are good people in the world."

In the picture below, and accompanying story, we learn that this dogs owner takes his arthritis suffering dog into Lake Superior every night as the only way that the dog can get some exercise, and also apparently the water eases the pain enough that the dog can fall asleep easily. 

It has gone viral, and athough there is no confirmation on the accuracy of the story, I want to believe it.   Great story of devotion if true.
