• Collect Photos: Ask pet parents to share their costumed pet pics via email, social media hashtags, or a shared album.
• Set Up Categories: Funniest Costume, Spookiest Look, Best Duo (human + pet), and Most Creative DIY are always crowd-pleasers.
• Use SignUp for the Event: Create a SignUp to recruit judges, schedule a viewing party for finalists, or organize volunteers to tally votes. Share it with one link and let everyone sign up at their own pace.
• Vote & Celebrate: Let the community join the fun. Host an in-person reveal, share winners online, and hand out treat baskets, ribbons, or gift cards.
• Bonus: Turn It Into a Fundraiser: Charge a small entry fee or ask for donations to benefit a local animal shelter or school club. A great way to add community impact to the fun.
