Oh please! History of Violence? Do we need to go through this again? Here is the muni's definition of a level-1-aggressive dog: "Level one behavior is established if an unrestrained animal is found to
menace or chase, and display threatening or aggressive behavior, or
otherwise threaten or endanger the safety of any person or domestic
animal". Source: http://www.muni.org/Departments/health/Admin/animal_control/Documents/Codified%20Title%2017%20(54%20page%20PDF).pdf

Read: All it has to do is display "threatening" behavior. To many people, apparently many posters here, this means getting barked at. So someone got barked at and filed a complaint about it, now the dog is "level-1-aggressive". Far, far from a history of violence. Stop blowing s*** far out of proportion.
