Daisy is scared of nothing except thunder.
Gatsby is scared of cooking smells. When ever we cook meals that are a little smokey he runs up stairs and hides in the Yorkie Club House (a space behind a futon that us humans can't easily get to) to shiver in seclusion.
Aggression is another issue. Gastby is aggressive towards anything new outside. He will bark at garbage waiting to be picked up, Christmas or Halloween decorations (those with motorized action are the worst), any litter moving in the breeze. Daisy is not aggressive towards anything except the vacuum cleaner when its running; she attacks it so fiercely that we have to put her in lockdown when we vacuum unless one of us can hold her.
