In the video, a dog is seen walking through a hallway with red cups arranged in a pattern on the floor. The dog sniffs and interacts with the cups as it moves through them. The hallway is long and narrow, with a white door at the end. The cups are arranged in a way that creates a path for the dog to walk through. The dog appears to be a medium-sized breed with a fluffy coat. The cups are all red with no visible markings or logos. The lighting in the hallway is bright, and the walls are painted a light color. There are no other objects or people visible in the video.
