In the video, a brown dog is seen behind a metal cage, barking and growling at a person who is standing outside the cage. The person is wearing a white shirt and black pants, and is holding a leash attached to the dog's collar. The dog appears to be agitated and is showing its teeth as it barks and growls. The person seems to be trying to calm the dog down, but the dog continues to be aggressive. The background is not clearly visible, but it appears to be an indoor setting.
