Dog Day

A man in a police uniform holds a black dog, then the scene cuts to a man in a white hoodie sitting on a chair with a small black dog, followed by a man in a black suit sitting with a large black dog standing beside him, then a man in a dark room flexing while a dog stands in front of him, then a man in a yellow shirt sitting barefoot with shoes in his hands, and finally a man sitting shirtless with a brown dog standing on his lap; the setting changes from an indoor room with lockers to an outdoor area with trees and a chair, then to a dimly lit room, and finally to a concrete patio.
