In the middle of the night, little infant Harper stopped breathing entirely. The family pup, Duke, knew just what to do.

When military working dog Layka loses a leg while saving the life of her handler, Army Ranger Trent McDonald, he vows to get her home safely.

At the Christmas parade in 2020, Abby collapsed from an episode of POTS (Postural Orthostatic Tachycardia Syndrome). Picaso, a shelter dog walking in the parade, pulled his handler into the crowd to save her. Then, she saved him.

In his twenties, before he became a nationally-renowned dog trainer, Matt Beisner was a jobless, self-loathing alcoholic with a rap sheet. And he was scared of dogs. When he went to the shelter one day and unexpectedly adopted a Jindo pup with a rap sheet of his own, Matt's life began to change. As Matt got clean and sober, he and Renge rode out some heartbreaking lows and euphoric highs, and Renge taught Matt how to slow down, live with kindness, and listen to what a dog's trying to say. Because dogs will tell us everything we need to know about life, if we just pay attention.
