My Dog Mattis (Unabridged‪)‬

My Dog Mattis is Mark Tappan's first book about his celebrity K9 dog Mattis. Mark and Mattis have been a team for over five years. Mark is a 15-year veteran with the police force, and Mattis is the most highly decorated dog in the department’s history. 

Mark has always seen dogs as a great bridge to connect law enforcement and the people they serve. They have grown their following on social media to millions. They are focused on using their platform to bring people together with fun and creative posts while giving insight into the special bond between a handler and K9. 

They appeared on the inaugural season of America’s Top Dog on A&E winning episode four, coming in a narrow second in the Champions Episode. That led to appearances on Entertainment Tonight, Good Morning America, Fox and Friends, and as studio hosts on LivePD.
