We look forward to welcoming you back to the museum this fall for free exhibitions and programs including:

Join us for a morning of dress-up, art activities, and furry fun at Hirshhorn Howl-o-Ween, our annual costumed celebration for dogs and their whole family. The one time of the year when Hirshhorn visitors can share art encounters with their well-behaved pets, Hirshhorn Howl-o-Ween invites dog owners and dog lovers of all ages to the Museum’s Plaza for a pre-Halloween party, featuring:

  • Breakfast snacks, coffee, mimosa bar, and dog-friendly treats.
  • Halloween-themed art making for humans and peanut butter “paw-traits” for dogs
  • A seasonal family photo booth

The event highlight is our canine costume parade and contest, where a celebrity panel of judges awards prizes for best costume in categories including:

Pup-ular Choice
Best in show! This dog is sporting the all-around favorite look that lets their personality shine through.

Dynamic Duo
Show off the bond you have with your canine companion through coordinated costumes. This pair makes us all want to be part of their pack.

Art Unleashed
It’s time you teach your dog to appreciate modern and contemporary art. This dog’s art-inspired costume deserves a spot in a museum. Extra points for Hirshhorn-specific references!

All proceeds from the event go to support the Hirshhorn’s education programs.
