The fear stages can present themselves differently...it might be a vacuum cleaner, or a bike, or a broom, etc.. Its a stage and it passes. Socialization is the key and the more you can socialize the better. My pup had a couple instances with people, but her fear of the vacuum was by far the worst one
That took some time, but she's good now. She also questioned the oscillating fan. Oddly enough she decided that she was bigger then the dust mop and could handle that.
