There are stickers popping up in Buffalo but they're for a good reason and they have to do with keeping mail carriers safe.

According to WIVB, a new initiative was started by a mail carrier in Corfu and it spread to Buffalo and even other parts of the United States.

If there's a dog that's deemed problematic, the mailbox of that dog's home gets an orange sticker. The house before it gets a yellow sticker to warn the mail carriers of the upcoming dog that lives at the house next door.

You can see the sticker below.

Postcards were also sent to Buffalo homeowners to let them know about the initiative and what they can do to help.

There's other ways to help keep mail carriers safe, such has shoveling snow on sidewalks and keeping potential hazards out of the way.
