Buddy, the incredibly cute puppy, has been stolen from Pets Paradise Melbourne Central in a brazen daylight robbery.
Pets Paradise staff told police a man, woman and small child were in the store when Buddy - who had a price tag of $1200 - was taken on Sunday afternoon.
The woman distracted a staff member while the man opened an enclosure to grab the 12-week-old black and white Cavalier shih-tzu cross puppy.
The couple then left the store without paying for Buddy.
Pets Paradise employee Thao Vo said she is incredibly sad and worried about Buddy's welfare.
"I'm desperate to know if she's alright," Miss Vo told Fairfax Media.
Sergeant Jennifer Locke said the dognapping is the latest in a spate of blatant thefts across Melbourne.
"It's disturbing that not only are they taking something that doesn't belong to them, and that they haven't paid for, but that they've done so with a young child with them," Sergeant Locke said.
Investigators are now combing through CCTV footage downloaded from the store's security camera.
The man is described as white and aged in his late 20s. He was wearing sunglasses, grey shorts and a white singlet.
The woman is also white, aged in her mid to late 20s. She has brown hair, and was wearing jeans with a white singlet and a number of long necklaces around her neck.
The window-front enclosure Buddy called home remains empty.
