A picture of a owner soothing his arthritic dog in a lake went viral last year. The dog, named Shoep, has now reached the age of 20, surpassing medical expectations. To celebrate his milestone, a picture was posted of him enjoying a birthday cake. The story of Shoep and his owner, John Unger, has inspired a charity called the Schoep Legacy Foundation, which has raised over $25,000 to help low-income families care for their aging dogs. The heartwarming story has attracted global attention and support from people around the world.
