Fine print
- Participation varies by store; Petco doesn't list which stores take part.
- Buying a costume in store is optional; a costume from home works.
- The page doesn't say how many treats per dog or whether supplies are limited.
- Petco's page lists the date without a year; it is the October 2026 events page (image names say october2026, footer ©2026).
- Release date: Petco gives none. 2026-10-17 is the day we read the event live on Petco's page.
