Back at the Barnyard - Season 2 - Eps 22: Man's Best Fiend
Duke wants a playmate, but no other animal wants to play with him, so the animals convince the farmer to get Duke a playmate. Unfortunately for Duke, the farmer brings Duke's arch-rival Baxter back to the farm, and Baxter causes trouble with the farmer while blaming everything on Duke, getting Duke in trouble and being put in the barn with the other animals. They try to stop Baxter but the farmer scolds them for hurting him. So they dress Otis as a bear so that Baxter pushes the farmer to it and get Baxter in trouble. The plan works but Duke accidentally attacks a real bear instead because Otis was late on cue.

Synopsis
What do farm animals really do when the humans aren't looking? Just ask Otis, a carefree "party cow" who inherited the job of keeping the barn... and it's residents... in order. But instead of responsibility, Otis is driven by an insatiable need for fun, fun, fun. Along with his barnyard friends Pip, Pig and Freddy, Otis will stop at nothing in his pursuit of a good time... which usually means a few close calls with humans and other threats to what really goes on behind closed barndoors.
