A dog named Riley has proven to become one of Britney Spears’ biggest fans this week after a video of Riley singing was put on Snapchat. Riley was singing the Britney Spears song “Toxic” and nailed it! Viewers were amazed to hear Riley’s vocal chords (which were squeaky barks) sound just like the music in the song. The video went viral in the matter of seconds! Matthew Hardin (Riley\’s owner) took the video of Riley and is a very proud that his dog has become famous.
