A possible mountain lion attack involving a dog was reported on the evening of March 25 to the San Mateo County Sheriff's Office. This is the second reported mountain lion attack since March 17.

Around 9 p.m. in the area of Alpine Road and Interstate Highway 280 near Portola Valley last week, the Sheriff's Office received a report that a medium-sized domestic dog was possibly attacked outside and carried off by a mountain lion.

At around 9:45 p.m. March 17, a Woodside resident, who lives near Raymundo and Marva Oaks drives, scared off a mountain lion attacking her dog. This attack was not far from Huddart Park.

The most recent attack wasn't witnessed, but a mountain lion was seen leaving the area around the time the dog was noticed to be missing, according to the Sheriff's Office.

Deputies were not able to locate the mountain lion or the dog.
