10.37.010 - Purpose of this Chapter.

Within the County of Los Angeles there are potentially dangerous and vicious dogs that have become a serious and widespread threat to the safety and welfare of the citizens of the County, which should be abated. The provisions of this chapter set forth the procedures by which the Department can find a dog to be a potentially dangerous dog or a vicious dog and the consequences of such a finding. This chapter is intended to supplement rather than supplant any other remedy available under state statute or County ordinance.
