In 2026, Americans spent $920 million on pet Halloween costumes; 23% of Halloween participants buy costumes for their pets, and that share keeps rising every year

But more interesting than how much was spent is what was bought, because the direction of pet costumes in 2026 clearly flipped: pets went from props dressed in costumes to active members taking part in the family's Halloween

Here is a breakdown of the most noteworthy trends in 2026

Classics always win, but the way they win has changed

First, an answer you may have already guessed: pumpkins are still number one

The official NRF 2026 ranking is very clear: pumpkin first, hot dog second, ghost third, then bat, bee and spider tied, cat, superhero, Batman and dog tied, witch, lion and vampire tied, and finally Chucky, devil, dragon and Scooby-Doo tied

Pumpkins took 11.6% of the share, hot dogs 5.9%, ghosts 2.8%; these numbers don't look big, but across the tens of millions of pet-owning households in the US, every percentage point means hundreds of thousands of pets in pumpkin costumes walking the streets

But the classics of 2026 are no longer the classics of ten years ago

Petco's fall collection this year has more than 300 products, most priced under $20, with prices starting at just $3; Petco's senior vice president Jenny Wolski said something key: today's families want to include their pets in the celebration, with products that reflect each pet's unique personality while putting calm and safety first

To put it another way: classics are still winning because they don't hassle the pet; a pumpkin cape just sticks on with velcro, no pulling over the head, no leg straps, no mask; for a dog wearing clothes for the first time, it's the lowest-friction introduction

PetSmart's 2026 collection confirms the same logic; in their Thrills & Chills line, pumpkin, bat, devil and angel, glowing skeleton tracksuit, dragon and dinosaur —— these are all slip-on-and-go styles, with no complicated multi-layer structure and no accessories that need to be tied on

Trend one: IP collaborations became a whole-family business

The biggest structural shift in pet costumes in 2026 is that IP collaborations no longer only make clothes for people, but also make pet versions at the same time

KPop Demon Hunters is the most representative example this year

The movie became a global hit on Netflix in 2025, won the Oscar for best animated feature, and a sequel is confirmed; for Halloween 2026, Disguise (JAKKS Pacific's costume division) launched a full KPop Demon Hunters costume line —— covering adults, kids, toddlers and pets

What's the core item of the pet version? Rumi's purple braided wig

Not a full costume, just a wig. Put Rumi's signature purple braided wig on your cat or dog, and they've "joined HUNTR/X". The clever part of this design is that it lowers the barrier to "pet participation" to the absolute minimum. You don't need to put a dog in a full K-pop idol stage outfit; you just put a wig on it, take a photo, and take it off. The whole process takes less than thirty seconds.

There are also glowing temporary tattoos —— Rumi and Jinu's demon marks, which can be replicated with glow-in-the-dark tattoo stickers. Stick them on your pet (or on yourself), and when you take a photo with the lights off, the whole vibe of the photo changes.

Wednesday Addams is another IP that the pet market takes seriously. Rubies' officially licensed pet version Wednesday costume includes a classic black dress (with white collar and cuffs) and a braided wig with a chin strap —— between $22 and $32. The wig is secured with a chin strap, so it won't fly off when the pet shakes its head. This detail shows the designer really considered the "actual experience of pets wearing clothes".

Trend 2: Matching human and pet apparel goes from niche to mainstream

This is the most notable consumer behavior change of 2026.

In Petco's collection this year, "matching human and pet apparel" is listed as a separate category. Specific products include little devil hoodies (pet version + human version) and skeleton hoodies (pet version + human version).

PetSmart is also pushing in the same direction. Their collection includes pink cowboy hats and bandana sets —— one for the pet, one for the owner.

Why does this matter?

Because "matching human and pet apparel" solves a very practical photo problem: when you and your dog are standing together in matching outfits, the narrative logic of the photo is completely different. Before, you were holding a dog in a pumpkin costume and taking a photo saying "my dog is so cute". Now, you and your dog are both wearing skeleton hoodies standing at the door, and the photo says "we're a team".

And the consumer logic of this trend is very smooth: you were already going to buy yourself a Halloween costume, so spending a few extra dollars to buy a matching one for your pet has extremely low marginal cost but extremely high emotional return.

Trend 3: No longer just for cats and dogs —— small animals and reptiles have a place too

An underrated but very real change in 2026 is that pet costumes are no longer just for cats and dogs.

Petco's 2026 collection explicitly lists a devil costume for bearded dragons and a ghost costume for guinea pigs. PetSmart's collection covers pumpkin, spider, scorpion, and snake styles for dogs, cats, small pets and reptiles.

This isn't weird, it's a direct reflection of changing pet owner demographics, bearded dragons and guinea pigs aren't niche in American pet households, especially among younger pet owners who increasingly choose small pets that don't need walks or large spaces, when these people see products saying my pet can join Halloween too, their buying impulse is the same as dog owners

Trend four: funny styles continue to dominate social media

If you've scrolled through pet Halloween content, you've probably seen these things:

Hot dog costume, this is one of the most photogenic pet costumes of 2026, a dachshund in a hot dog costume is comedy in itself, that's why the hot dog has held the number two spot on the NRF ranking from 2024 to 2026

Banana costume, PetSmart made it a style for cats, dogs, and small animals, a yellow curved shell goes over the pet, plus a green banana stem hat, simple, easy to understand, instantly recognizable, this zero-explanation-cost costume spreads most efficiently on social media

Pink cowboy, PetSmart's pink cowboy hat and bandana set hits the intersection of two 2026 trends: the rise of pink at Halloween, and sweet-cool style rewriting traditional Halloween aesthetics

Pet wigs, one of Amazon's best-selling pet products is a 6-pack pet wig set for $29.99, adjustable straps fit cats and dogs, the logic is the same as Rumi's wig in KPop Demon Hunters: it doesn't cover the whole body, doesn't restrict movement, and you just take it off after photos, and a wig's funny factor is higher than a full-body costume —— a cat in an afro wig is ten times funnier than a cat in a full pumpkin costume

But there's one thing no trend can avoid: whether pets are actually comfortable

In 2026, all major retailers are saying the same thing when they launch pet costume lines

Petco's official statement says: putting calm and safety first

This isn't PR talk, it's a real response to consumer behavior, in recent years, videos of pets having breakdowns in clothes have increased on social media, and consumers are starting to realize one thing: not all pets are suited to wearing clothes, and freezing after being dressed isn't being good, it's stress

The healthiest trend of 2026 isn't buying more, it's buying better

The test is simple: after putting it on, can the pet walk normally, can it wag its tail, can it sit, can it stand up on its own, if it starts walking backwards, freezing in place, shaking its body wildly, or trying to paw off the clothes —— take it off, it's not needing time to adjust, it's saying I'm not comfortable

If the costume test fails completely, a Halloween-themed bandana or bow tie is already enough participation, PetSmart's line includes Halloween-themed dog bandanas, a few dollars each, with very high pet acceptance

One sentence to sum up 2026 pet Halloween costumes

Classic picks (pumpkin, hot dog, ghost) are still the sales backbone, because they don't hassle pets. IP collabs (KPop Demon Hunters, Wednesday) turn pets into part of a whole-family look. Matching pet-and-owner costumes went from niche to mainstream, because the photo logic shifted from my pet is so cute to we're a crew. Small animals and reptiles are no longer overlooked

And behind all these trends, one principle never changes: a costume is only good if the pet feels comfortable in it
