In the video, a person is holding a clear plastic cup in front of a dog. The dog is standing on a rug in a living room, and the person is holding the cup in such a way that the dog can see its reflection. The dog seems to be intrigued by its reflection and starts to sniff the cup. The person then moves the cup around, and the dog follows it with its eyes, trying to catch the reflection. The dog seems to be confused and curious about the reflection, and it follows the cup as the person moves it around. The living room is well-lit, and there are some furniture and other objects in the background. The dog is medium-sized with a white and grey coat, and it appears to be a Siberian Husky. The person holding the cup is wearing a blue shirt, and only their hand and arm are visible in the video.
