Directed by Cody Cameron, the film theatrically premiered in Russia on October 21, 2010 and was released direct-to-video in the United States and Canada on January 25, 2011.

One spring morning several years after the events of the second film, Boog awakens after hibernation and plans an annual guys' trip to spend time with his best friends.

Meanwhile, Mr. Weenie and his friends, including a reformed Fifi and a newcomer named Nate, spot Boog on a TV commercial for the circus.

The next morning, Ursa begins to enjoy her new life in the forest and ultimately becomes Boog's mate and the honorary aunt of Elliot and Giselle's kids.

Elsewhere, Mr. Weenie and the pets travel to Devils Tower with Bob and Bobbie as they've been currently searching for aliens, and the circus begins its long journey back to Russia.

[4] DVD Verdict gave the film a negative review, saying: "This tiresomely predictable tale exemplifies everything that's wrong about straight-to-DVD animated sequels to big-budget mainstream films: the plot is utterly predictable and rehashes a lot of beats from the original effort, the major voice actors have been replaced by poor substitutes and the quality of the animation has dropped dramatically (most of the visuals are on the level of a video game or one of those cheap CGI Saturday morning TV shows)".

Shaffer of IGN gave the film a slightly positive review saying the animation is fine, and the kids are bound to enjoy it, but Open Season 3 boasts a dull story that feels like it's on autopilot.
