In the video, a German Shepherd is sitting on a wooden deck, and a person's hand is seen holding a treat. The dog licks the treat from the person's hand, and then the person moves the treat away. The dog then licks the deck, and the person's hand moves the treat back towards the dog. The dog licks the treat again, and the person's hand moves the treat away again. This process repeats several times, with the dog licking the treat from the person's hand and then licking the deck. The dog appears to be well-trained and obedient, following the person's hand movements. The video captures the interaction between the dog and the person, showcasing the dog's obedience and training.
