In the video, a man is seen lying on the floor of a hallway, and a dog is running around him. The man is wearing a black shirt and black pants, and the dog is brown and white. The man then stands up and starts running after the dog, who is running away from him. The man catches the dog and picks it up. The dog appears to be a small breed, possibly a terrier or a similar type of dog. The hallway is well-lit, and there are doors on either side of the hallway. The man and the dog seem to be playing together, and the man seems to be enjoying the interaction with the dog.
