Courage Wolf is an image macro series derived from the original Advice Dog series. In contrast to Advice Dog, who might unknowingly lead you to do something you'll regret, Courage Wolf will help you achieve greatness with often extreme, overwhelming advices.
Entitled “Snarling Gray Wolf,” the original photograph was taken by nature photographer Jeff Vanuga in Montana and uploaded to Corbis Images. The exact date of upload remains unknown, but Google Insights data shows that the meme began to gain traction beginning sometime in December 2008. According to various accounts including MemeBase and Encyclopedia Dramatica, the Courage Wolf macro series was reportedly picked up by 4chan's /b/ (random) board, the birthplace of Advice Dog macro series.
