Los Angeles County's supervisors voted unanimously Tuesday to strengthen the county's regulations on vicious dogs in the wake of a dog attack that killed a woman in the Antelope Valley town of Littlerock in May.
The new rules expand the definition of a "potentially dangerous dog" to include those that have attacked livestock. Previously, the law covered only dogs that had attacked people or pets.
Attacks on livestock "are often a precursor of attacks on pets or people," county animal control Director Marcia Mayeda wrote in a report to the board.
Owners of dogs that are declared potentially dangerous can be ordered to adhere to conditions such as buying homeowners insurance, putting their animals through obedience training, keeping them on the property unless muzzled and leashed, and keeping them in a secure yard or pen.
In the wake of the fatal attack in Littlerock, the supervisors also approved additional funding to add animal control officers and a communications center in the Antelope Valley.
