This was a toy I had when I was little. It runs on three AAA batteries. When you press the button on its head or speak to it nearby, it makes cute movements and barks. I've confirmed it works, but it sometimes takes a while to start moving if it's not in good condition. Currently, it takes a few minutes. It hasn't been used for a long time, so there's almost no dirt, but the motor makes a noise. It moves, but please understand that it's a junk item. For those who enjoy maintenance and want to have fun with it. Please note that AAA batteries are not included.
