Here's a detailed description of the video: A small, gray and tan Yorkshire Terrier is standing on its hind legs, trying to reach a plastic bag held by a person. The person is standing on a sandy beach, wearing blue jeans, a light-colored shirt, and black sneakers. The dog is balancing on a colorful blanket spread on the sand. The person is holding the bag above the dog's head, seemingly teasing it. Another person is sitting on the blanket, partially visible. The beach has some grass and trees in the background under a bright sunlight.
