Pamela Anderson’s pet dog has gone missing.

The actress’ Chihuahua Luca was being looked after by her parents in Malibu, while Pamela films new movie “Blonde and Blonder” in Vancouver, Canada, when it disappeared.

The pooch was being walked on a private beach on Sunday afternoon (Nov 19, 2006) when it suddenly vanished.

Pammy is distraught about her missing mutt and is convinced Luca has been “dog-knapped.”

The former “Baywatch” star - who is an ardent animal rights campaigner - wrote on her personal website: “My little Chihuahua Luca went missing off a beach in Malibu on Sunday afternoon.”

“I think somebody took him. I was returning home from Vancouver and spoke to my parents at 3.30 p.m..”

“They were on a private beach with him, which he knows very well.”

“He normally runs on the beach but has been on medication and could have been groggy and not himself.”

“There was a construction crew and an odd person walking along the beach on the public pathways. I need him back.”
