Roxie hates the vacuum! If I even bump into it while I am in the laundry room (which is upstairs, and she is downstairs) she will freak out and start barking.
She will chase it around and bite the hose on the side while I am actually using it. She actually ripped all the rubber off the sides of the hand vac I have!
Yesterday I was vacuuming upstairs, and she actually came up to chase it around and attack it. Silly dog.
