If you take a walk through Greenpoint, you may spot a sticker of a shepherd or dachshund on the back of a stop sign or along a streetlamp.

"Oh, I've never seen this before," said Stella Williams, as she admired a picture of a brown and white Maltese made into a sticker form, stuck against a recycle bin. "It is very cute."

Williams is one of the many Greenpoint residents who find stickers of smiling dogs in unexpected places - it's a mysterious trend taking over the borough.

The stickers are all thanks to Nick Padilla, a seventh-grade teacher who anonymously began placing stickers of pup pets around the neighborhood.

From the backs of stop signs to bar bathroom-tiled walls, Padilla said his only goal is to put a smile on someone's face and showcase a local canine companion.

"I just want people to see more dogs and have their dogs get the recognition they deserve," says Padilla.

After tragically having to put down his beloved dog Hobbs, a tiny but mighty Yorkie, Padilla said he wanted a way to remember him. So, he created small stickers of his furry friend and pasted them around the neighborhood.

After the stickers stared to get recognition, Padilla came to a sudden realization.

"The more I thought about how much I like seeing my dog in random places, maybe other people would want to see their dog in random places," Padilla said with a smile.

Padilla created an anonymous Reddit post requesting to have the community send him pictures of their pups - to beturned into a sticker and placed around the neighborhood. After just three weeks, several sticker requests started to roll in. Padilla eventually created an Instagram account, where he would then post a photograph of the pet, with a caption detailing fun facts about them.

"I've had a lot of people reach out who are excited about it - it's really cool to see," Padilla said. "There's something really special about bond with our dogs."

Padilla said he plans to continue to pursue his pup sticker project, and hopes to eventually raise enough money to help support local dog shelters.
