The final episode of Secret Life of Dogs airs Thursday, July 26 at 8:00 pm.

They may be our best friend, but how much do you actually know about dogs, their physiology, thoughts, and lives? The Secret Life of Dog examines that inner life, getting under the fur of our closest companion. And if you want to dig deeper, here are various segments from other PBS shows further exploring our canine friends.
