This is one of the many stories on the internet that will both break and warm your heart. In this clip, meet Hoshi. Hoshi is an American Eskimo dog who had both of his eyes removed after suffering from a painful eye disease. Six months before his surgery, his family adopted a Pomeranian named Zen and the two became fast friends. Now Zen acts as a guide dog while the pair travels the world hiking, camping and kayaking. The dogs’ owners say the pair has a special bond deeper than friendship. This is really amazing and tissues may require while watching.
