The dog is angry.

A man in a yellow shirt sings into a microphone on a stage before a large crowd, then turns and reaches out to the audience, who are raising their hands. The scene cuts to a small dog being held up to a horse's face, with the dog barking and the horse leaning in. The scene returns to the man on stage, now singing with his eyes closed and hand on his chest. The final scene shows a man in a white shirt falling backward in slow motion against a bright sky.
