Los Angeles police officials were notified Monday of a pit bull attack that left a 2-month-old baby seriously injured at a home in Woodland Hills.

Sgt. Zoltan Mako, watch commander of LAPD’s Topanga Division, said officers were notified by the Los Angeles County Department of Children and Family Services at about 5 p.m. of the attack that occurred earlier that day.

The baby boy had been taken to Northridge Medical Center and was in critical condition. However, Mako said he was expected to survive.

The pit bull was initially penned in at the home in the 22600 block of Clarendon Street, Mako said. However, when a delivery person came to the door and a parent answered, the dog managed to get loose and maul the child, he said.

The boy sustained facial injuries and broken bones, Mako said.

Los Angeles Animal Services visited the home Monday night, he said.

This dog was under quarantine at West Valley Animal Shelter in Chatsworth on Tuesday, according to Ashley Rodriguez, a spokeswoman with Los Angeles Animal Services. After the quarantine period is over, which is determined by the Los Angeles County Department of Public Health, Animal Services will reach out to the dog owner to determine the outcome for the animal.

Topanga Division detectives investigated the incident, Mako said.
