Dog Shop

PetSmart's dog Halloween costumes come in sizes from small breed to XXL, with styles ranging from classic pumpkins to playful food and character looks. Add treats, toys, and Halloween accessories to round out the look.

Choose from classic pumpkin costumes to a hot dog costume for your dog, sized from small breed up to XXL. Every costume should fit without restricting your dog's vision, hearing, or movement.

Our dog Halloween toys include squeaky and interactive options to keep your pup engaged. Pair the look with Halloween bandanas and harnesses to match the costume.

Reward your dog with Halloween-themed treats made for the season, good for training or just marking the occasion.

Start with fit: a good costume shouldn't restrict your dog's movement, breathing, or bathroom access, and it shouldn't have small parts they could chew off and swallow. Factor in temperament too, since some dogs happily wear a full outfit while others do better with just a bandana. If you'll be out after dark, look for a costume with reflective or bright detailing so drivers can see your dog.

There isn't a verified ranked list, but a few styles show up consistently every season: pumpkin and classic Halloween costumes, superhero and character costumes, and simple accessories like bandanas or hats for dogs who don't love a full outfit. Which one is right comes down to your dog's size and how much they tolerate wearing something new.
