Jennifer Salome's 2008 silver Altima was stolen from the Lukoil gas station at Berlin and Burnt Mill roads in Voorhees last night at around 11:00.
Her 6-year-old Shih Tzu Lex was curled up in the front passenger seat of the car when she ran inside the store at the Lukoil.
During the two minutes she was inside, a woman drove off in Jennifer's car with the dog.
"He's really calm. He has the sense that if there is something wrong, he'll pick up on it," Jennifer said. "My best guess is she didn't realize he was there until she started driving off."
The store owner provided Jennifer with surveillance video that shows the suspect getting into the car, which was parked in front of the door, and driving away.
The suspect appears to be tall and thin with blonde hair in a messy bun, a dark hoodie and green sweatpants.
The car has PA Plates number GZV1776 and a University of Delaware license plate frame.
What is not known is whether she got onto I-295 once she left the lot.
At this point, Jennifer's far less concerned about the car, which is insured, than her beloved pet.
And she's hoping someone will turn Lex into the police or an animal shelter and soon, before she has to explain to her 14-month-old son why his beloved playmate "Doggie" isn't at home.
"'Doggie' was actually one of the first words he said. The two of them play around and now when he asks, 'Where's Doggie?' what am I going to say to him?" Jennifer said.
Jennifer says Lex is very low-key. He weighs about 13 pounds.
If anyone has seen him or the car, they should call Voorhees police.
