My goofy girl runs for cover as soon as the Vaccum is turned on... However the broom is a different story

She grabs, growls, and won't let go .... It is very funny..
I watched the dog wisper, and he had a few dogs that were always going nuts with the broom. What he did was have the broom and step forward towards the dog... He made a swoosh sound, and the dog would back down. He said it is a dominance thing. I decided to give it a try, sure enough it worked! I could not believe it !
Suzi backed off and just laid there . No more broom attack. It was so easy. I did not even have to make a sound. She tried it about twice, then quit going after the broom in one training.
