Extra Features:

• Commentary features director Ben Leonberg and producer Kari Fischer.
• Behind-the-Scenes (9:54, HD) is a fascinating look at the creation of "Good Boy." What's presented here is a mix of BTS footage and numerous scenes from the endeavor, watching director Ben Leonberg and producer Kari Fischer create a creepy picture basically by themselves, laboring to pull off some difficult visual ideas and work with their dog, Indy. Since vocal performances were added after the shoot, the raw footage here humorously inspects the push to "direct" Indy, who needed special commands and coaching to pull reactions and movement out of him. Also highlighted is visual effect shots and Leonberg's messy transformation into "The Shape."
• Making Of (4:33, HD) is hosted by director Ben Leonberg (joined by his star, Indy), who summarizes the herculean effort to create a suspense movie with his dog. The shoot carried on for over three years, forcing the helmer to go slowly and carefully with his shots, hoping to gets something special out of his canine star. BTS clips are provided to understand the labor involved (one eight-month-long stretch of production only produced five minutes of usable footage), and Leonberg also goes into film school mode, exploring his use of "The Kuleshov Effect" to help trigger audience interest in Indy's performance.
• Development Diary & Short Films (5:30, HD) examines the early stages of brainstorming on "Good Boy," putting co-writers Ben Leonberg and Alex Cannon to work trying to figure out how to tell a story from a dog's POV. Three short films are included, each exploring how to handle Indy's behavioral quirks and camera presence, ranging from test shoots to a mini-movie, pushing Leonberg to best understand the canine's abilities and selling points, including his unwavering stare.
• A Theatrical Trailer has not been included on this release.
