A man and his dog are walking naturally in a park in Tehran. The man holds the dog's leash in a relaxed grip, and the collar sits comfortably around the dog's neck. The leash hangs naturally, with a slight curve as the dog moves beside him. The park is filled with greenery, tall trees, and winding paths. Sunlight filters through the leaves, casting soft shadows on the ground. In the background, the Tehran skyline is visible, with Milad Tower standing tall, slightly blurred in the distance. The scene blends urban life with nature, creating a peaceful and realistic atmosphere.
