SAN DIEGO » A Chihuahua that vanished from its San Diego home has been reunited with its owners — five years after it went missing.

Dawn Danielson, director of San Diego’s animal services department, told City News Service on Thursday that the plucky canine, named Cookie, was found wandering the streets in the Golden Hill area near downtown San Diego on Saturday.

Cookie had disappeared from the South Bay area, several miles away.

Danielson says Cookie was reunited with her owners — thanks to a microchip implanted in the dog that stored its owners’ information.

It is not known what Cookie has been up to for the last five years.
