A Halloween Party Where Dogs are Invited, too!
A dog-friendly, costumed gathering in support of shelter animals! Bowser’s Boo Bash is an autumnal soiree filled with frights, delights, and oodles of bewitching activities for both mortals and canines!
In 2025, Bowser’s Boo Bash raised a startling $141,965 to support Oregon Humane Society’s programs and services, including adoptions, subsidized veterinary care, and humane law enforcement. Animal-advocates from the mid-Valley, and beyond, gathered to snuggle kittens and puppies, hug a therapy llama, and cheer on a runway of costumed pups all while celebrating the bond between pets and the people who love them.
