Rooster (Secret Life of Pets 2)

Rooster is a farm-dwelling sheepdog who works on a farm in the countryside. This sheepdog is a character who is responsible, dutiful, hard-working, and serious though laid-back.
Rooster is first introduced growling at Max for accidentally drinking out of his water bowl. He then introduces himself.
When Max and Duke take a trip to the countryside so Max can try to rid his nervous tick, a terrifying turkey chases him. Rooster bays to catch their attention and save Max. Later that night, when Max compliments on how off-guard Rooster caught him, he advises him to get rid of the cone. Max nervously tries to protest about the cone being a 'medical device,' but Rooster ignores and shakes the cone off his head. "There, you're cured. Hallelujah..." he states after. In the Secret Life of Pets 2, Max develops empty nest anxiety for his owner's son, Liam, that leading so much to a nervous tick. So when Max visits the countryside, Rooster will seize the opportunity on guiding Max to ditch his neuroses, find his inner alpha, and give Liam a little more freedom.
Although Rooster does not have all duties and work with his country lifestyle. One of his likes as to rid of all the duties of a farm day is to sing to the moon on top of a car, on a starry night. As seen from the trailer sent from Universal Pictures Ireland, Max is in awe at Rooster's howling. Rooster requests to join him. Max does so and is even in more awe. He starts the chorus and him and Rooster howl in harmony at the full moon together.
