Petco is turning every one of its stores into a Halloween venue this month, and almost everything on the list costs nothing. The retailer's own earnings call confirmed "Halloween photo opportunities and even a costume party" for October, and its executives described the Petcoween program in a brand interview.
A store-level event calendar circulating among deal watchers fills in the dates — including a Petcoween costume contest on October 17 and free pet portraits on October 24. We verified what Petco has officially said and separated it from what is still reported-only.
That distinction matters here: petco.com's own event pages are bot-blocked and don't currently list the full calendar, so the specific dates below carry a caveat we explain in detail.
The headline freebies: free food samples most Saturdays, a free trick-or-treat treat for costumed pets from October 17-31, free Petcoween portraits, and a costume contest with prizes. With 1,377 U.S. stores on the map, there is very likely one near you.
Here is the full rundown — the confirmed facts, the reported calendar, the fine print that trips people up, and backup plans if your local store skips an event.

What Is the Petco Petcoween Event Series?
Petcoween is Petco's umbrella name for everything Halloween: a 300-plus-item seasonal product drop, store decorations, and — the part we care about — free in-store events. The name is official.
Petco's July 27 press release announcing the "Petcoween" collection is on Petco's corporate newsroom, with merchandising SVP Jenny Wolski calling Halloween "one of the biggest celebrations for pet parents."
The events side was confirmed at the executive level. On the September 2 earnings call, CEO Joel Anderson laid out the roadmap: "September brings Catco Month... Looking ahead to October, we will host Halloween photo opportunities and even a costume party." The full transcript is republished by AOL Money.
Petco's SVP of Brand also walked through the sequencing in a Future Commerce interview: Catember events run through October 4, "which will then transition to Petcoween, when Halloween costume contests, trick-or-treating, and other spooky soirees will be on the docket."
What we could not verify: the store-level dates and times listed below come from an event calendar shared by freebie trackers, and Petco's official pages were not reachable during our check (bot protection, not a dead site). Treat the calendar as high-probability but store-dependent — call your store to confirm before a long drive.
What's Free at Petco in October
Based on the reported store calendar, here is the full month laid out. Every event is walk-in, and none require a Petco Perks membership.
Date | Event | Time |
|---|---|---|
Every Saturday | Puppy playtime | 1-1:30 PM |
Oct 10 | Adoption meet-and-greet | Store hours |
Oct 11 | Wellness dog food sample | 2-4 PM |
Oct 17 | Petcoween party, costume contest | 2-4 PM |
Oct 17-31 | Trick-or-treat, free treat | All month window |
Oct 24 | Petcoween portraits, Hill's sample | All day + 2-4 PM |
Oct 25 | Champion dog food tasting | 2-4 PM |
Two everyday freebies run outside that table. Petco Zoo — the reptile, fish, and small-animal habitat section — is free to visit every day during store hours. And the Find Mews hide-and-seek game hides a cat somewhere in the store all month, with a "purr-ize" for kids who spot it.
The free samples deserve their own value note: fresh dog food sample days (Hill's on the reported calendar) are worth roughly $3-5 per pouch at pet-food prices, and a costume contest with prizes can offset the cost of a costume you were buying anyway. Petco's own Petcoween merch starts at $3 per the official release, so entering the contest does not require a $40 outfit.
The one date we could not confirm officially is October 17. The earnings call confirms "a costume party" in October, and the reported calendar pins it to October 17, 2-4 PM. If your store runs it on a different date, you will find out exactly one way: asking.
How to Claim the Free Petco Events Step by Step
Nothing here requires a code, app download, or RSVP. The process is deliberately low-friction, but four steps keep it smooth.
Locate your store via Petco's official site store finder and note its hours
Call or check the store page for the specific event you want — this is the step that de-risks the reported calendar
Bring vaccine proof for puppy playtime — the reported calendar explicitly requires it for pups 8 weeks to 6 months
Show up in the window — most sample events run 2-4 PM local; portraits run all day on October 24
Costume your pet for October 17-31 to trigger the trick-or-treat free treat
Check in with staff at each event so samples and treats are handed out to you
Membership is not required for any of the reported events. Petco did relaunch its free Petco Perks program this year — the earnings call credits it with easier point redemption — so joining at checkout is a sensible side-quest, not a gate.
Who Is Eligible?
Every event on the list is open to the general public. You do not need to be a Petco Perks member, an Autoship subscriber, or a customer at all. Any pet can join the costume contest and trick-or-treat window, and the puppy playtime has exactly two conditions: age (8 weeks to 6 months) and vaccination proof.
There is no purchase requirement anywhere on the reported calendar. The costume contest is the only event with a competitive element, and store-level judging means your odds are one-store, not one-million — a similar structure to the chain's Halloween contests going back decades.
One eligibility nuance: event participation can vary by store because these are store-level activations. Petco's corporate communications frame the program as chain-wide ("we will host..."), but a specific store can adjust dates around local staffing, adoption-partner schedules, or building constraints.
Important Fine Print to Know
This is the section that matters most, because the evidence here is layered. We split it into what is confirmed and what is reported, and we would rather you call one store than drive to one on a wrong assumption.
Confirmed officially: Petcoween exists; October includes Halloween photo opportunities and a costume party; the collection and campaign are live
Reported, unconfirmed officially: the specific date-time table above (Oct 17 contest, Oct 24 portraits, sample brands and slots)
Vaccine proof required for puppy playtime per the reported calendar
Trick-or-treat treat is in store — one treat per costumed pet, while supplies last
No third-party delivery angle — these are in-store-only activations
For context on how seriously Petco treats this program: the Q2 earnings call listed "community building retailtainment events" among the named sales drivers for Q3 and beyond, per the transcript carried by AOL. That is management telling investors these events will exist and be staffed — it is in their interest for your local store to run them.
Costume history, for the trivia-minded: Petco's Halloween costume contest tradition goes back to the 2000s, when the chain's "Howl-o-Ween" contest awarded winners an eight-pound bag of IAMS food and a $15 gift card with no purchase necessary. Twenty years later the mechanics barely changed — walk in, dress up, win pet swag.
Frequently Asked Questions
How do I find my local Petco's Petcoween event times?
The reliable path is the Petco website store finder plus a two-minute call to your store. Petco's corporate site confirms the Petcoween program exists, and its newsroom carries the seasonal releases, but the granular store calendar is distributed at store level. When we checked, petco.com's event pages were behind bot protection, which is exactly why the phone call beats the webpage this month.
Is the Petco costume contest really free to enter?
Yes. The reported calendar lists the October 17 Petcoween party and costume contest as a walk-in event with prizes and treats, 2-4 PM, and no purchase condition. That matches the chain's long contest tradition — the original Howl-o-Ween contest two decades ago was explicitly "no purchase is necessary." Costumes can be as simple as a $3 bandana from the official Petcoween collection; there is no entry fee at any price point.
Can my cat join the Petco events, or is it dogs only?
Cats are explicitly in scope. The Find Mews hide-and-seek game is a cat-themed store event running all month, and nothing on the reported calendar restricts the costume contest or trick-or-treat window to dogs. Small animals and reptiles get representation too — the free daily Petco Zoo habitat area is the chain's way of including everything from bearded dragons to guinea pigs. Only puppy playtime has a species-and-age gate, because it is a socialization event for young dogs.
What do I need to bring to Petco puppy playtime?
Two things: your puppy (8 weeks to 6 months old) and proof of vaccinations. The reported store calendar is explicit on both points, and the vaccine rule exists for good reason — a room full of young dogs is exactly where parvo and other exposures spread.
No RSVP is listed, no fee is mentioned, and Petco Perks membership is not required. If you arrive without records, staff will likely turn the pup away, so snap a photo of the vaccine certificate before you leave home.
When does Petco trick-or-treating start and end?
The reported window is October 17 through October 31, in store, during regular hours. Bring your pet in costume — or pick one up in the Petcoween aisle — and staff hand out a free treat. The window conveniently starts on contest day, so October 17 is the single highest-value visit of the month: costume contest, photo ops, and the first day of trick-or-treat treats all in one trip.
What if my Petco store does not run these events?
Petco frames October's events as a chain-wide commitment on its earnings call, but activation detail is local.
If your store skips an event, the backup plan is simple: PetSmart runs its own free Halloween month — we documented the PetSmart trick-or-treat and spooky-pet events including a free tote — and for the two-legged kids, the free LEGO witch build at Barnes & Noble covers the same weekend window.

About Petco
Petco Health and Wellness Company (NASDAQ: WOOF) operates 1,377 stores across the United States as of its most recent quarter, per its own earnings call. The San Diego-based retailer spans food, supplies, veterinary hospitals, grooming, and — increasingly — what management calls "retailtainment": in-store events like Petcoween, the Piggy Cup guinea-pig soccer tournament, and Feed the Sharks.
The company positions these events as community building with a sales tailwind. In the Q2 2026 call transcript, management said such events "benefit store traffic and provide an in-store selling opportunity" — transparent language for a free-events program that also, unsurprisingly, ends near the treat aisle.
Its seasonal drops, like the 300-item Petcoween collection, start at $3.
For the official word on October programming, the Petco newsroom and the main site are the primary channels; store-level calendars vary.
