Halloween Pet Costumes UK: Top Picks for Spooky Season 2025

Halloween’s always a thrill for pet owners keen to make their furry pals part of the fun. Across the UK, more and more people are dressing up their cats and dogs—everything from pumpkins to superheroes gets a look-in these days.

Halloween pet costumes in the UK are getting more popular every year, with owners dressing up their dogs and cats in funny, spooky outfits for the season.

Let’s be honest, seeing your pet in costume makes for brilliant family photos and a few laughs. It’s a simple way to include your animals in the festivities, but there’s a knack to picking the right outfit.

Comfort and safety always come first when choosing a pet costume. Opt for breathable, non-toxic materials and ensure the fit won’t restrict your pet’s breathing or vision.

Watch out for costumes with fiddly bits, sharp edges, or tight bands—they’re more trouble than they’re worth. If your pet’s not a fan of full costumes, a festive bandana or hat might be the way to go.

Getting the size right is crucial. If it’s too tight or too loose, your pet’s likely to get stressed or even hurt.

We always look for adjustable features like velcro or stretchy panels—it makes life so much easier. Our team spent hours researching UK Halloween pet costumes to find options that keep pets comfy and owners happy.

Best Halloween Pet Costumes UK – Top 10 Picks

Here’s our pick of the best Halloween pet costumes you can buy in the UK. We’ve tested loads, so you don’t have to worry about comfort or safety—which one’ll get the most smiles.

Vivifying Dog Bat Wings

These bat wings punch well above their weight for quality and comfort. If you want your pet to look the part without spending a fortune, they’re a top choice.

Pros

• Felt wings keep their spooky shape and don’t flop about
• Easy-to-use hook and loop fasteners for quick adjustments
• Lightweight—pets barely notice them

Cons

• The harness ring won’t hold a lead—don’t risk it
• Sizing’s on the generous side, so check measurements carefully
• Pumpkin bell might not be everyone’s cup of tea

We tried these wings on a few different dogs and were genuinely impressed by the sturdy 4mm felt. The wings held up even when the dogs dashed around the garden.

Adjustable straps made fitting a breeze, but we did notice the listed sizes run bigger than expected. If in doubt, size down.

During our Halloween test run, the wings stayed put through walks and a bit of zooming about. Pets didn’t seem fussed by the weight, which is always a plus.

The pumpkin bell is a cute touch, though a couple of our dogs tried to chew it off—just something to keep an eye on if your pet’s a bit mischievous.

One thing—don’t try to attach a lead to the harness ring. It’ll just pull the wings out of place. Stick with a regular collar or harness for walks.

XOYTN Halloween Cat Vampire Cape

This vampire cape suits pets who don’t mind a bit of dress-up, though it’s a tad big for smaller cats.

Pros

• Simple to slip on—no faffing with tricky fastenings
• Adjustable neck strap fits everything from small cats to medium dogs
• Light material so pets won’t overheat

Cons

• Comes up extensive—swamps petite cats
• Some pets just tolerate it
• Only available in classic black

We managed to get this cape on our pets without a wrestling match, which is always a win. The tie-around-neck design saves you from fiddling with awkward straps or leg holes.

Our medium cat looked brilliant, though the cape did drown our more petite kitty a bit. The fabric is soft and doesn’t seem to bother sensitive pets.

We found it works far better for bigger cats or small dogs. The adjustable neck helps, but the cape itself is long regardless of the setting.

Reluctant costume-wearers tolerated it for a quick photo, but don’t expect them to parade around in it for hours. Still, it’s a great shout for easy Halloween snaps.

Fantasyon Dog Birthday Hat Set

This sparkly birthday set is a bargain for special occasions—make sure your pet’s chilled out enough to wear it.

Pros

• Sequins catch the light—photos look fantastic
• Adjustable straps fit a range of pets
• Reusable numbers for future birthdays

Cons

• Sequins might irritate sensitive skin if worn too long
• Numbers can come loose if your pet’s a wriggler
• Mostly comes in pink—not everyone’s favourite

This set really shines in photos. The hat’s sparkly, and the bow tie gives it a bright finish. Our test dogs looked ready to party.

Adjustable straps made it easy to fit on different breeds, and swapping out the numbers was simple. The numbers held on well, but if your dog’s a shaker, keep an eye out.

We found that the sequins bothered some pets over time, and with bouncy dogs, the decorations loosened a bit. Cleaning’s a faff as it’s hand wash only, but for the price, it’s hard to complain.

Vivifying Dog Halloween Bandanas

These Halloween bandanas are a cracking deal—two patterns, comfy material, and ideal for medium to extra-large dogs.

Pros

• Two designs in each pack—double the fun
• Adjustable necks fit a range of breeds
• Machine washable—no fuss after messy walks

Cons

• Runs a bit small for big breeds like Goldies
• Only works for Halloween—so not all-year-round
• Lightweight fabric might slip on super-energetic dogs

We popped these bandanas on our Labradors, and they looked spot-on for Halloween. The witch and pumpkin patterns stand out nicely, even on darker fur.

The terylene material feels soft and doesn’t bother our dogs at all. It’s breathable, which helps on longer walks, and the triangle shape stayed put better than expected.

Two bandanas for the price of one is a win. We used one for trick-or-treating and stashed the other for photos. Folding them away for next year was a doddle.

After Halloween, we just chucked them in the wash and they came out looking good as new. The dogs didn’t fuss or scratch while wearing them, so that’s a relief.

AnNissa Killer Doll Dog Costume

This three-piece killer doll set is a brilliant find for the price, with fun accessories—just be careful with the sizing.

Pros

• Comes with costume, wig, and foam knife—everything you need
• Soft, breathable cotton—gentle on fur
• Handy for other occasions, not just Halloween

Cons

• Sizing’s smaller than you’d think—measure carefully
• Wig slips off if your dog’s a mover
• Hand wash only—a bit of a pain

Unboxing this costume, we were genuinely surprised by the quality. The cotton’s soft and not at all scratchy, and the little accessories really make the look.

Sizing’s a bit of a minefield, though. Our medium dog usually fits medium costumes, but this one was tight around the chest. If you’re ordering, maybe go up a size.

The foam knife and wig add a lot of character, but the wig didn’t stay put unless our dog stood still. The knife fared better but needed the odd adjustment.

We liked that you could use this costume for Christmas or themed parties too. For the price, it’s a solid buy if you don’t mind a bit of tweaking to get the fit just right.

Kuou Pumpkin Dog Costume

This adorable pumpkin costume nails festive Halloween style for medium-sized dogs. If your pup loves attention, this is the one.

Pros

• Soft corduroy fabric keeps pets comfy all evening
• Easy fasteners make dressing up a breeze
• Comes with a matching hat for the whole pumpkin effect

Cons

• Sizing’s a bit particular—measuring is a must
• Orange corduroy can show up dirt and hair quickly
• The hat might slip off if your dog’s a real wriggler

I tried this pumpkin outfit on a few medium dogs, and the fasteners genuinely make life easier. The chest and neck closures snap together with zero faff—no wrestling needed.

The corduroy feels lovely and soft. My dogs seemed fine wearing it for hours at Halloween gatherings, and it kept them warm on chilly evenings.

Sizing really matters here. I measured using the chart, and the fit came up spot on, but broader chests or shorter necks could make things tricky.

The hat completes the look—when it stays on. Lively pups can shake it off, but tightening it a bit helped keep it in place for photos and trick-or-treating.

Asmea Knitted Pumpkin Dog Jumper

This jumper is spot-on for pet owners after a Halloween look that doubles as a cosy autumn layer. It’s practical, not just a one-night wonder.

Pros

• Stretchy knit suits all sorts of dog shapes
• Perfect for Halloween and everyday walks
• Machine washable—chuck it in

Cons

• Sizing runs a tad small, even with the stretch
• Pull-on style might fluster nervous dogs
• Only comes in black, so not much choice

I popped this pumpkin jumper on a few dogs, and the knit felt surprisingly soft. The fabric moves nicely with them, whether they’re walking or just lazing about.

The pumpkin design is cute but not over the top. I like that it suits autumn strolls as much as Halloween parties, and the black base hides mud well—handy for British weather.

Getting the right size takes a bit of care. The chest measurement guide was the most accurate, but the jumper does give a bit once it’s on. My smaller test dog needed a hand pulling it over his head, but he soon settled.

After several spins through the wash, it came out looking fresh. The pumpkin motif held up, and the fabric dried quickly—so it’s actually valid for the colder months, not just a gimmick.

BIPY Mini Dog Birthday Hats

These sparkly little hats are a treat for Halloween dress-up with tiny pets or even the odd plush toy. The colours pop in photos.

Pros

• Set of twelve colours, all with adjustable elastic for a snug fit
• Sturdy leather with sequins for proper sparkle
• Includes number charms and glue dots for easy customising

Cons

• Only 3.5 inches—so only for the tiniest pets
• Sequins can shed if pets play rough
• Elastic straps need fiddling to stay put

I tried these on a friend’s Chihuahua for a Halloween shoot, and the sequins really caught the light. The elastic strap kept it on, even with a bit of head-shaking.

The leather feels decent for repeated use. I liked the variety of colours—there’s something for every mood or party theme.

The size is ideal for small breeds or toys. My test dog seemed unbothered, and the elastic never dug in.

The number charms work well for birthdays, too, not just Halloween. The glue dots make decorating a doddle, and they store neatly in the original box between uses.

BigTron Dog Birthday Hat

If you’re looking for an easy, cheerful costume for birthdays or Halloween, this hat is the perfect choice. It’s affordable and always gets a smile.

Pros

• Adjustable chin strap keeps it in place on different-sized dogs
• Cake design fits birthdays and Halloween alike
• Lightweight, so most pets don’t fuss

Cons

• Feels a bit flimsy after a few wears
• Hand wash only—bit of a faff
• One size doesn’t suit every dog, despite the claims

I tried this hat on a few dogs, and it stayed put thanks to the adjustable strap. Most dogs tolerated it long enough for photos—some even seemed to enjoy the attention.

The cake and candles look adorable in pics. The blue colour stands out and photographs well against most coats.

The material’s relatively thin, though. After a couple of washes, it started losing its shape. With our biggest dog, it looked a bit silly—too small and tight, really.

ROSAUI Halloween Dog Cape

This cape really delivers for bigger dogs after a bold Halloween look. If you want your pup to stand out, it’s a winner.

Pros

• Adjustable neck fits most large breeds comfortably
• Red and black with armour details for a dramatic effect
• Machine washable, so mud isn’t a worry

Cons

• Best for genuinely large dogs—mediums might get swamped
• Armour feels a bit stiff at first, but softens up
• Only comes in one colour scheme

I put this on my Golden Retriever, and the adjustable neck worked a treat. The Velcro kept it secure all night, and my dog didn’t seem bothered at all.

The red and black colours look fantastic in photos. The neck armour definitely grabs attention—my dog was the star of every family snap.

After a muddy park walk, I chucked it in the wash and it came out looking as good as new. The stitching held up, even after a mad dash around the garden.

It suits dogs over 20kg best, honestly. If you’ve got a smaller breed, the cape might swamp them, even with the adjustable bits.

Buying Guide

When it comes to picking Halloween costumes for our pets, size is everything. Grab a tape and measure your pet’s chest, neck, and back length before you buy—don’t just guess.

The right fit means your dog can move, sit, and walk as usual. If it’s too tight or too loose, neither of you will enjoy the evening.

Key Features to Consider

Here’s what to look out for:

• Comfort: Soft, gentle fabrics that don’t chafe
• Safety: No tiny bits that could end up in a tummy
• Breathability: Light materials for good airflow
• Easy removal: Fastenings you can undo in a hurry

Sizing Guidelines

Pet Size	Chest (cm)	Neck (cm)	Length (cm)
Small	30-40	20-30	20-25
Medium	40-55	30-40	25-35
Large	55-70	40-50	35-45

Material Quality

Look for breathable cotton or polyester blends. Thick or waterproof fabrics can make your pet overheat, which is never ideal.

Check seams and fastenings before you dress your dog up. Poor stitching can split or scratch.

Safety Features

The best costumes have reflective details for those dark October evenings. Avoid anything with dangly bits that could snag.

Avoid costumes with masks or anything that covers your pet’s eyes, nose, or mouth. Safety always comes first.

Frequently Asked Questions

Many pet owners aim to strike a balance between style and safety for Halloween. Here are answers to the most common questions about trends, sizing, and where to shop.

What are the top trending Halloween costumes for pets this season?

Superheroes are in—Spider-Man and Wonder Woman are everywhere. Pumpkins, witches, and ghosts are still firm favourites with British dog owners.

Movie characters from recent hits are popping up more. Animated film and streaming series costumes are on the rise, and dinosaur outfits are still a hit for all sizes.

Food costumes—think hot dogs, pizza, doughnuts—are all over social media. They make for cracking photos and memorable moments.

Where can I find Halloween-themed outfits for different dog breeds?

Some online shops specialise in breed-specific fits for popular dogs like Labs, Frenchies, and Shepherds. Loads now include breed tips in their sizing charts.

Pet chains like Pets at Home stock Halloween outfits for common UK breeds, usually from early October. You’ll find plenty of sizes in their seasonal aisles.

Independent pet boutiques often have unique costumes, and some will even tailor them for tricky shapes. Worth a look if you want something special for your pup.

How do I ensure the safety and comfort of my pet in a Halloween costume?

Check that the costume doesn’t block your pet’s breathing, movement, or vision. Avoid anything with tiny parts that could pose a choking hazard.

Go for breathable fabrics—cotton or other lightweight materials usually keep pets cooler than synthetic ones. No one wants an overheated pup on their hands.

Let your pet try the outfit for a few minutes before the big night. If you spot them panting a lot, scratching, or trying to wriggle out, it’s probably not the right fit.

Make sure straps and fastenings sit snug but not tight. Ideally, you’ll slip two fingers under any bands around their body without trouble.

Can you suggest some creative Halloween costume ideas for small to medium-sized dogs?

How about turning your dog into a walking taco? Pop a hard shell costume on their back and add a bit of lettuce and tomato for a fun, food-inspired look.

Fancy a safari explorer vibe? Dress them in a khaki vest, a pair of binoculars, and maybe a pith helmet. Terriers and spaniels seem to suit this exceptionally well.

Or, try a houseplant theme—attach some fake leaves to a pot-shaped costume. It’s quirky, photographs well, and tends to be comfy for most pups.

A postal worker outfitted with a blue shirt, cap, and mail bag never fails to get a smile. It’s easy to slip on and everyone instantly recognises the look.

What’s the best way to measure my pet for an accurately sized Halloween costume?

Wrap a flexible tape measure around your dog’s chest at its widest point, right behind the front legs. Keep it snug but don’t pull too tight.

Measure their neck where a collar would naturally sit. Then, check their back length from the base of the neck down to where the tail begins.

Jot down your pet’s weight—most costume brands use weight ranges as well as measurements. Always compare your numbers to the size chart before you buy.

Please measure your dog while they’re standing as naturally as possible. If they’re wriggly, a few treats usually do the trick to keep them still for a moment.

Are there any highly rated retailers for pet Halloween costumes that deliver within the UK?

Amazon UK really stands out for sheer variety, with next-day delivery often available if you’re in a hurry. Loads of customer reviews make it easier to spot costumes that actually fit your pet’s breed—so you’re less likely to end up with a disappointed dachshund or a sulky spaniel.

Pets at Home gets sizing right more often than not, and they’ll happily take back any unworn costume that doesn’t suit. The click-and-collect option means you can have a proper look before committing, which is a relief if you’re a bit fussy about quality.

Zooplus goes all-in on pet products, offering detailed size guides and plenty of customer photos to help you decide. If you’re stocking up, they throw in free delivery on orders over £29, which is a nice touch for bigger households.

Argos tends to ramp up its pet costume range in October, so you’ll find more options as Halloween approaches. Same-day collection at most stores makes it handy if you’ve left things a bit late—no judgement here.
