This is another way Kito wins the strange dog contest--when we lived in our apartment, he HATED the vacuum--he would bark, and try to attack and bite it--he had to be locked up sometimes when we ran it!! Since we moved into the house, he could care less about it--you can run it right up next to him, and he won't move--usually I'll just go around him!! The dustbuster really freaks him out though--he can't handle it--weirdo!!
