Ultra-photorealistic 5-second video. Use the first image as the exact starting frame. The dog must remain identical throughout the entire video. Preserve the exact face, eyes, fur texture, tri-color markings, body proportions, pose, lighting, camera angle and background. ACTION: A gentle feminine hand enters the frame from the side. The hand naturally picks up the open, unfastened collar lying on the ground in front of the dog. The dog remains calm and still. The hand lifts the collar and carefully places the open strap around the dog's neck. The hand fastens the buckle and secures the collar. The gold medallion naturally hangs from the collar and gently swings. The hand briefly adjusts the fit, then exits the frame. The video ends exactly matching the reference end image.
