In the video, a person is seen holding a rock in their hand and placing it in the mouth of a dog. The dog appears to be a Labrador Retriever and is sitting on a wooden bench. The person then proceeds to rub the rock back and forth across the dog's teeth. The dog seems to be enjoying the experience as it closes its eyes and smiles. The person continues to rub the rock on the dog's teeth, and the dog remains calm and content throughout the video. The setting appears to be outdoors, possibly in a park or a backyard. The video is shot in daylight, and the focus is primarily on the interaction between the person and the dog.
