1. Free Petcoween Party & Costume Contest
Petco’s current October 2026 in-store events calendar includes a Petcoween Party & Costume Contest for pet parents who want a seasonal activity with their dog or other pet. The event combines a costume contest with free treats, prizes, and a Halloween photo opportunity. Petco describes the event as part of its free October in-store programming and specifically notes that participation varies by location. That means the core promotion is national, but your nearest store may handle attendance, prize quantities, or event logistics differently.
2. When Is the Petcoween Event?
The Petcoween Party is scheduled for Saturday, October 17, 2026 from 2 PM to 4 PM. Petco says the costume contest begins at 2 PM, so participants who want to enter should arrive before the start rather than showing up near the end of the two-hour window. Stores may have limited event supplies, prize quantities, or staffing. If you are planning around the contest, it is smart to arrive early enough to check in and ask a staff member where the event area is located.
3. What Freebies Are Included?
Petco’s official event listing mentions three free elements: treats, prizes, and a scary-cute Halloween photo opportunity. The listing does not promise a specific treat brand, prize value, number of prizes, or professional photographer. Treat and prize details may therefore differ from one participating store to another. If your pet has food allergies or dietary restrictions, ask what treat is being offered before accepting it. The photo opportunity may be a themed backdrop or event area rather than a formal portrait session.
4. How the Costume Contest Works
The official listing says the costume contest starts at 2 PM and invites customers to bring their best-dressed pet. Petco does not publish one universal judging rubric on the national event page, so individual stores may determine how winners are selected and how prizes are awarded. Keep your pet’s comfort in mind when choosing a costume. Avoid clothing that restricts breathing, movement, vision, hearing, or bathroom access. A simple bandana, cape, or lightweight accessory may be a better choice for pets that are not comfortable in full costumes.
5. Which Petco Stores Are Participating?
Petco repeatedly notes that participation varies for its October events. Use the button above to open the current in-store events page and use the Find a Store option to locate your nearest Petco. If the event is important to you, call ahead and ask whether that store is hosting the October 17 Petcoween Party, whether registration is required, and whether there are any local rules for entering the costume contest. A quick confirmation can help avoid a wasted trip if a location is not participating.
6. Is a Purchase Required?
The Petcoween Party is presented by Petco as part of its free October fun in store, and the national event page does not state that a purchase is required to attend the party, receive a free treat, use the photo opportunity, or enter the costume contest. However, free items and prizes may be limited while supplies last. Petco also sells Halloween costumes and treats during the season, but those paid products are separate from the free event activities.
7. Tips for a Safe Halloween Pet Event
Before attending, make sure your pet is comfortable in public settings and around other animals and people. Keep dogs leashed and use a secure carrier or appropriate restraint for other pets. Bring water, waste bags, and any item that helps your pet stay calm. Avoid candy and human Halloween treats because common ingredients such as chocolate and xylitol can be dangerous to pets. If your pet becomes stressed, overwhelmed, or reactive, it is better to leave early than force them to stay for the contest or photo opportunity.
8. Final Thoughts
The free Petco Petcoween Party is a fun Halloween freebie for pet owners who want a seasonal outing without paying an event admission fee. The key details are October 17, 2026 from 2–4 PM, with the costume contest beginning at 2 PM, plus free treats, prizes, and a Halloween photo opportunity. Because participation varies by store, verify the event with your local Petco before heading out and arrive early if you plan to enter the costume contest.
