ENCINO -- A man in his 70s is hospitalized after he was attacked by two neighborhood pit bulls while walking in Encino.

The man was walking on the sidewalk when two pit bulls escaped from a yard in the area of 17938 Burbank Boulevard at 9:36 p.m. Sunday and attacked him, said Lt. Jeff Perkins of the Los Angeles Police Department's West Valley Station.

He appeared to have tried to fight off the dogs by raising his hands, sustaining bite marks on both arms, Perkins said.

The man was knocked to the ground, and a couple of drivers came to his aid, scaring off the dogs with their car horns and nudging one with a car bumper, Perkins said.

"They helped scare the dogs off."

The man, in his 70s, was bitten several times on his arms and was taken to a hospital in Woodland Hills in stable condition, Perkins said.

The Los Angeles Department of Animal Regulations is investigating the attack.

They say the dogs had escaped from the backyard of a nearby home; the owners were away and the house sitter had not realized the dogs were missing.
