Hot on the heels of September’s “Catember” giveaways, Petco is rolling out even more freebies for pets and their humans in October. This month, you can take your pet trick-or-treating in-store for a free snack through Oct. 31.

No rewards membership is needed for trick-or-treating, and no purchase is required to join in. If you’re always looking for ways to stretch your pet budget, these are worth adding to your calendar. (We’re tracking freebie deals at lots of other stores too, plus getting ready for free pet photos with Santa.)

Petco is offering two in-store freebies during the month of October.

There are two main events to know about this month:

  • Free Trick-or-Treating at Petco (Available to Everyone) : From Oct. 25 - 31, bring your pet in costume and get a free treat from the Treat Bar.

  • Howl-o-ween Scratch & Win (Membership Required) : Every shopper with a membership who visits on Oct. 25 gets a scratch-off card, with prizes ranging from 10% - 40% off. Ten lucky winners will even walk away with a completely free transaction, up to $499. A free Vital Care Core membership is required for this one.

Get free treats for pets in costume when you visit Petco between Oct. 25 and Oct. 31.

Petco Free In-store events in October 2025

As confirmed on Petco's website, you can visit any Petco location Saturday, Oct. 25 through Friday, Oct. 31, your pet will get a free treat from the Treat Bar just for showing up in a costume (I've assembled a few costume deals at the end of this post).

No rewards membership is required for the in-store trick-or-treating event, but it was required for the Howl-o-Ween giveaway.

The free treats they're giving out Oct. 25 - 31 are simpler than most Petco promotions. You don't need to be a Petco rewards member, you don't need to buy anything, and you don't need to bring proof of anything. Just visit in-store during the events to claim your pet's freebie.

But for the Howl-o-Ween Scratch & Win giveaway, you needed to be a rewards member.

Get 50% off select Petco Halloween costumes and accessories through Oct. 31.
