Police said his 21-year-old owner left the dog on a leash outside Green Corner Fish and Famers Market on the corner of Humbolt Street and Flushing Avenue. When she left the store around 9 p.m., all that was left was the leash.

“It’s heartbreaking, because they’re your kids too, they’re part of your family,” resident Arlene Bonner told CBS2.

“Why would somebody take someone’s dog?” wondered resident Jimmy Helvin.

“That’s the cruelest thing you can do to someone. I would die if someone did that to my dogs. It’s evil,” resident Lucia Stacey said.

The owner immediately notified police and put out a call on social media to help find Theo. According to the post, he has an underbite, cloudy eyes and lump on his thigh.

Flyers posted around the neighborhood say a large cash reward is being offered for the dog’s safe return with “no questions asked – we won’t press charges.”
