In the video, a person is seen wearing gloves and holding a syringe. They are injecting something into the neck of a dog. The dog is lying down on a white surface and appears to be calm and relaxed. The person's movements are gentle and careful, indicating that they are likely a veterinarian or a trained professional. The syringe is clear, allowing us to see the liquid inside, and the person's hands are steady as they administer the injection. The dog's fur is a mix of white and black, and it seems to be a medium-sized breed. The background is blurred, but it appears to be a clinical or medical setting.
