In the video, we see a close-up of a dog's open mouth as a person wearing gloves examines its teeth. The person uses a tool to inspect the dog's teeth, and we can see the dog's tongue and teeth clearly. The person's hands are covered in gloves, and the background is blurred, but we can see the dog's fur and part of its body. The person appears to be a veterinarian or a dentist, and the dog seems to be calm during the examination.
