Shep is an adult male shepherd dog with brown fur. He speaks with a German accent. He wears thin, square glasses.
He is seen wearing a pink collared button-down shirt, deep green pant-suit with jacket and dress pants, light pink and a blue paisley print scarf draped around his neck, deep green and white polka-dot necktie, and dark brown loafers.
Very little is known about Shep's personality.
He gets a call from Shep Von Trapp, who offers him the role of Oscar nominee announcer after Jimmy Fallon, the original host, was hit with a bus outside of Halloween in January. He was trying to take a selfie, and "broke his face." Not long before his surgery, Captain Peanutbutter talks him into doing it despite his melancholy. He says, he'll call Mr. Peanutbutter later.
Later, at the Oscars, Mr. Peanutbutter and Todd accidentally drop the phone after it rings. They leave the area to find it. After doing so, it is revealed it was Captain Peanutbutter calling, and he announces his surgery was a success—but before celebrating, Mr. Peanutbutter realizes that the red envelope containing the nominations handed to him by Shep Von Trapp was gone. They decide, after tricking and running away from Von Trapp, to make up the nominees by looking at the list of actors.
