Alpharetta K-9 who survived three-story fall advances in TV competition

An Alpharetta police K-9 has something to bark about.

Police K-9 Mattis and his handler Sgt. Mark Tappan won the episode of A&E's new competition show "America's Top Dog" that aired Wednesday.

Tappan has been with the department since July 5, 2006 and is now the leader of their K-9 team. Mattis is about six years old.

The Alpharetta Department of Public Safety congratulated the pair on Facebook after the winning episode aired.

“My goal was to make my family, friends, Department and community proud and show off how amazing my best friend is,” Tappan told The Atlanta Journal-Constitution.

And that best friend has had quite the comeback: Mattis was injured in 2016 after bounding over a 30-foot retention wall while running down a suspect.

The show is hosted by sports broadcaster Curt Menefee, K-9 school owner and former Secret Service member Nick White and sideline reporter Jamie Little.

Each week’s winning team gets $10,000 and an additional $5,000 to donate to the animal charity of their choice. Tappan said he has chosen the Georgia Police K9 Foundation. In the last week, top competitors come back to the finale course to earn the title of “America’s Top Dog” and an extra $25,000.

As Tappan put it: “Mattis makes me look better than I am.”
