Robert’s Pizza & Dough Co. has made a name for itself by creating delicious pizzas with a family dough recipe that took 20 years to perfect. More recently, the famed Chicago pizzeria has been making headlines for hosting an annual pet parade.

This year’s Howl-o-Ween event—the third annual occasion—will take place October 28 from 2–4 p.m. local time and feature canines and humans alike decked out in Halloween garb to celebrate the season.

A professional pet photographer will be on site to capture the very best moments, and a winner will eventually be announced in three respective costume categories: cutest, scariest and most creative. Dog treats will be available for the pups, and there will be Halloween cocktails for the humans.

The Howl-o-Ween parade is just one of the ways Robert’s Pizza gets into the fall spirit. The restaurant, located in the Streeterville neighborhood, is rolling out a National Pizza Month fundraiser to support breast cancer awareness. Robert’s founder Robert Garvey is committing $1 from certain menu items sold all month long, with proceeds eventually donated to Real Men Wear Pink of Greater Chicagoland by the American Cancer Society.

Menu items include the Lia and Cup & Char, two of the restaurant’s most popular pies. The Lia is a classic cheese pie, featuring mozzarella and fresh tomato sauce. The Cup & Char is a classic pepperoni with Calabrian peppers, fresh mozzarella and tomato sauce. Whether a customer gets a pie to-go or dines in while soaking up Chicago’s final patio days, ordering one of these classic pizzas gives back to a great cause.

Also benefiting Real Men Wear Pink is Robert’s Tickled Pink Cocktail featuring tequila orange juice, lime and grenadine. Available all month long, $1 from every cocktail will be donated back to the organization.
