The autumn afternoon in Dallas was warm, filled with the gentle rustle of falling leaves and the sound of children playing at the park. Little Lily ran across the grass in her pink puffer jacket, holding a bright yellow flying disc.

Officer Miller: Keep your eye on K-9 Duke! He’s tracking something fast!

Officer Davis: Hold on, Miller! Where is he heading?

The massive German Shepherd darted across the lawn with terrifying speed, his eyes locked on the edge of the tree line where Lily was playing.

Lily: Look how high this frisbee goes, Mommy!

Officer Miller: STOP! Duke, release!

Officer Davis: He isn't stopping! Get over there now!

Before anyone could react, the heavy tactical dog leaped through the air and slammed into six-year-old Lily, tackling her hard onto the leaf-covered ground.

Sarah: NO! NO! Get off her! Somebody help my baby!

Mark: MOVE THE DOG! CALL 911 RIGHT NOW!

Officer Miller: STAY BACK! THIS IS TEXAS POLICE!

Sarah: He's killing her! Get him off!

Officer Miller: Don't move an inch! Look under the bush where her toy landed!

Mark: What are you talking about? Your dog just attacked our daughter!

Officer Miller: Good boy, Duke... Good boy.

The parents stood frozen in absolute terror, completely unaware of the deadly threat that had been inches from their child's face.
