Back at the Barnyard (2007)

Season 2: Episode 33

Duke is excited when his sister Stamps comes to visit, but is shocked when he realizes that Stamps is engaged to his arch-enemy, Baxter. However, the animals learn that Baxter is after Duke and Stamps' uncle's priceless dog bone collection. When they try to frame Baxter for chewing up a couch at his bachelor party (so that Stamps will dump him because she hates couch-chewers), Duke beats him to it and now scolded in front of Freddy and Peck. So at the altar, Duke tells Stamps about Baxter going after the dog bone collection, she dumps Baxter and he is launched in the field.
