The agency will seek to have any dogs involved in the attack destroyed, Mayeda said. The others will be licensed, spayed or neutered as required and three of them — the legal limit — will be returned to the owner while the rest will be placed for adoption if they are friendly, Mayeda said.
However, there still was a chance that the attacking animals were strays.
"In these areas, you might have a situation where people dump animals out in rural areas," said John Mlynar, a spokesman for the nearby city of Palmdale.
People living near the site of the attack said stray dogs constantly roam the area and have attacked people before.
"It's really scary," Diane Huffman, of Littlerock, told KABC-TV. "I don't know what to think. I really think I'm going to be getting a gun to protect myself."
The jogger's death was the latest of at least five deadly dog attacks in California in the past two years.
Last month, Claudia Gallardo, 38, of Stockton, was mauled to death by a pit bull in the front yard of a home where the dog lived.
In February, Elsie Grace, 91, of Hemet, was killed by a pair of pit bulls at a motel.
In June 2011, two pit bulls escaped from their yard and mauled a neighbor in her San Diego backyard. Emako Mendoza, 75, suffered arm and leg amputations before dying months later. The dog's two owners were convicted of involuntary manslaughter.
In June 2012, an 8-month-old boy, Tyzhel Latella McWilliams, was mauled to death by a pit bull at a home in Lemon Grove, near San Diego.
Anyone who spots an aggressive dog, even behind a fence, can contact Los Angeles County animal control officers to investigate, Mayeda said.
If behavior problems are found, the owner will be cited for violations or encouraged to seek dog training.
"They'll be put on notice that there are people concerned about their animals," she said.
