PetSmart is having its annual "Howl-o-Ween Costume Party" at all store locations on Thursday, October 25, from 6 to 8pm.

This year, PetSmart will provide creative pet costumes and accessories, along with a special grooming package. Customers can also bring their own costumes.

An in-store parade will take place at 6:45. Pet parents can purchase a photo package to capture the memory, including an exclusive glow-in-the-dark photo frame, for $6.95, or $4.95 with a Pet Perks savings card.

It wouldn't be "trick or treat" without offering treats in exchange for tricks. Accredited dog trainers will also be on hand to offer treats to teach dogs some new tricks, such as "high-fives" and "waving goodbye".

PetSmart is also offering a variety of new and creative pet costumes, ranging from Darth Vader, Batman, a frog, a little devil, among others. You can see the whole line at PetSmart's Halloween Shop.
