In the video, a person wearing gloves is seen holding a syringe and injecting a substance into the mouth of a small dog. The dog appears to be a small breed with long, shaggy fur. The person's hand is steady as they administer the injection, and the dog remains still throughout the process. The syringe is clear, allowing us to see the liquid inside, and the dog's mouth is open to facilitate the injection. The background is blurred, but it appears to be a clinical setting, possibly a veterinary office. The person's movements are precise and careful, indicating that they are likely a professional.
