Sergeant Mark Tappan and his K9 companion, Mattis, have a highly engaged and devoted fan base of over five million social media followers. This down-to-earth duo never anticipated winning A&E's Top Dog , fulfilling countless on-going media requests, and interacting with an ever-increasing social media fan base. Although, it's Mark and Mattis' special bond and likeability as a team that has their audience clamoring for more. K9 Mattis is one of the most decorated police K9s of all time with over 200 arrests and over 2 million in cash seized and even has a Purple Heart.
