Let me set the scene. It is October 30th. You have a party tomorrow, a dog who sheds like it is a full-time job, and a shopping cart with nothing in it. Sound familiar?
Three measurements, five safety rules. One page, print it before you shop.
Dressing up your dog is officially a whole thing now, and the pet costume aisle has gotten genuinely good in the last couple of years. The problem is that a lot of dog Halloween costumes are still junk. They rip in ten minutes, they are sized for a hamster, or your dog hates them so much she does the frozen-statue thing and refuses to walk.
So I did the digging. Every costume below is a real Amazon listing that I checked myself — star rating, review count and available sizes, all read off the live product page. I broke them into small, medium and large so you are not squinting at a size chart at midnight.
Dressing up yourself too? I have a companion post with 10 budget-friendly Halloween costumes under $30 for the humans in the house.
Let us get your dog dressed.
Want all fifteen in one place? I saved every costume in this guide to a single Amazon list, so you can scroll them side by side instead of opening fifteen tabs. See the full Pet Halloween Costumes list →

How to Pick a Dog Costume That Actually Fits
Do not skip this part. Sizing is where most bad dog Halloween costumes reviews come from, and it is almost always fixable.
Costume sizing is not the same as dog food sizing. A “large” costume is often built for a 30-pound dog, not your 80-pound lab. Grab a soft measuring tape and get three numbers before you buy anything:
- Neck: around the base of the neck, where the collar sits
- Chest: around the widest part, just behind the front legs
- Back length: from the base of the neck to the base of the tail
Then compare those to the brand’s own size chart — not the breed name in the title. Two golden retrievers can be twelve pounds apart. And when you are between sizes, size up. A slightly baggy costume is comfortable. A tight one is coming off in the driveway.
Quick reference for this post: small = under 20 lbs (Chihuahua, Yorkie, dachshund, mini poodle), medium = 20–50 lbs (beagle, corgi, border collie, cocker spaniel), large = 50 lbs and up (lab, golden, German shepherd, husky, boxer).
Best Dog Halloween Costumes for Small Dogs (Under 20 lbs)
Small dogs get the widest selection of dog Halloween costumes, and honestly the best photo ops. These five have real staying power in the reviews.
1. Fitwarm Halloween Pumpkin Dog Dress
4.6 stars · 5,064 ratings · around $15 · sizes XXS–L
The pumpkin is the single most popular pet costume in America, and this is the version that keeps earning five stars. It is a soft stretch dress rather than a stiff outfit, which is exactly why dogs tolerate it — no bulky headpiece, no velcro digging into anyone. Over 5,000 people rated it and it is still sitting at 4.6, which tells you the size chart is honest.
Best for: the classic Halloween look with zero drama.
2. Fitwarm Halloween Ghost Dog Dress
4.7 stars · 2,486 ratings · around $15 · sizes XXS–L
A 4.7-star average on a costume is genuinely rare, and this little ghost dress earned it. Same soft, stretchy Fitwarm build as the pumpkin, just spookier. Reviewers keep mentioning that it washes well and does not lose its shape, which matters if you are the kind of person who breaks the Halloween bin out every year.
Best for: tiny dogs who hate anything structured.
3. Fitwarm “Little Miss Bootiful” Halloween Dog Dress
4.7 stars · 3,018 ratings · around $17 · sizes XXS–L
If your feed needs one good caption-ready photo, this is the one. Black and hot pink, cheeky slogan, and a 4.7 average across 3,000+ ratings. It also reads as a cute fall outfit rather than a full costume, so you get more than one wear out of it.
Best for: small girl dogs and Instagram.
4. NACOCO Cowboy Rider Dog Costume
4.5 stars · 5,597 ratings · around $18 · sizes XS–XL
You have seen this one — the tiny cowboy strapped to your dog’s back, hat and all. It looks like the dog is being ridden into town. Nearly 5,600 ratings at 4.5 stars, and it works on a Chihuahua as well as on a beagle. Fair warning: some dogs need a minute to get used to something sitting on their back, so do a test run before the party.
Best for: the biggest laugh for the smallest effort.
5. SCENEREAL Bumblebee Bandana, Tutu and Leg Sleeves Set
4.6 stars · 1,324 ratings · around $18 · small to medium
Bee costumes land in the most-popular list every single year, and this one is smart about it: instead of one rigid bodysuit you get a bandana, a tutu and little leg sleeves. You can use all of it for the full look or just the bandana if your dog is being difficult, which makes it one of the few costumes with a built-in plan B.
Best for: dogs who will tolerate some costume, but maybe not all of it.
Best Dog Halloween Costumes for Medium Dogs (20–50 lbs)
Medium dogs are the sweet spot for dog Halloween costumes — most brands actually stock these sizes, and the fit tends to be more forgiving than at either extreme.
6. Kuoser Dog Tuxedo and Bandana Set
4.7 stars · 5,382 ratings · around $28 · sizes S–XXL
Not strictly a Halloween costume, but hear me out. A 4.7-star average across 5,300+ ratings is the highest in this entire round-up, and a dapper little tux works for Halloween, weddings, birthdays and Christmas cards. It has a built-in D-ring so you can clip a leash straight to it, which is a detail cheap costumes never bother with.
Best for: the most wears per dollar of anything on this list.
7. Fitwarm Halloween Bat Dog Pajamas
4.6 stars · 4,758 ratings · around $15 · sizes XS–XXL
Bat costumes rank in the top five most popular pet costumes every year, and this one is done as pajamas — full-body, soft and lightweight. Because it runs all the way to XXL it is a rare costume that genuinely covers medium dogs instead of pretending to.
Best for: cool-weather trick-or-treating.
8. California Costumes UPS Pal Dog Costume
4.2 stars · 6,653 ratings · around $19 · multiple sizes
The most-reviewed costume in this entire post — 6,600+ people have bought and rated it. It is the delivery-driver bit, complete with a little parcel, and it lands every time precisely because your dog already has strong opinions about the actual UPS truck. The 4.2 average is honest: it is a novelty costume, not a garment, and it fits like one.
Best for: the joke that writes itself.
9. Rubie’s Hot Dog Pet Costume
4.5 stars · 481 ratings · around $27 · sizes up to large
Hot dog sits second only to pumpkin in popularity every year, and it is best on a long-bodied dog — a dachshund or a corgi turns the whole thing into a sight gag. Rubie’s has been making licensed costumes for decades and it shows in the bun: it holds its shape instead of collapsing into a sad pool noodle.
Best for: long dogs and people who like a classic.
10. CuteBone Dinosaur Dog Pajamas
4.5 stars · 504 ratings · around $14 · stretchy, multiple sizes
Dinosaur is one of the fastest-growing searches in the pet costume category, and the pajama build is the reason this one works: stretchy fabric with a spiky ridge down the back, so your dog gets the full dino silhouette without a rigid shell strapped to them. It is also the cheapest full-body costume here.
Best for: dogs who will not tolerate anything stiff.
Best Dog Costumes for Large Dogs (50 lbs and Up)
This is where the search gets hard. Most dog Halloween costumes stop at “large,” which is nowhere near big enough for a shepherd or a lab. These five all go to XL or beyond and still have the reviews to back them up.
11. Puoyis Bat Wings Costume
4.3 stars · 8,594 ratings · around $6 · dogs and cats
The most-reviewed product in this post by a mile, and the cheapest. It is a wing harness that clips over the shoulders rather than a full-body suit, which means no overheating and no fighting your dog into sleeves. For a big dog who runs hot, that difference is the whole ballgame.
Best for: big dogs who hate full costumes.
12. EXPAWLORER “Bad to the Bone” Skeleton Dog Hoodie
4.5 stars · 2,476 ratings · around $18 · sizes up to 2XL
A proper skeleton hoodie that goes all the way to 2XL, fleece-lined, with a leash hole cut into it. Because it is a real sweatshirt it doubles as a cold-weather layer once Halloween is over, which is a nice trick if you hate single-use purchases.
Best for: cold-climate dogs and October walks.
13. Rubie’s DC Comics Wonder Woman Pet Costume
4.4 stars · 4,623 ratings · around $19 · sizes S–XXXL
This one earns its spot on sizing alone: it runs all the way to XXXL, which almost nothing else does. Licensed Rubie’s quality, 4,600+ ratings, and it is a dress-and-cape setup that goes on over the head in seconds — no wrestling four legs into four holes.
Best for: giant breeds — Great Danes, mastiffs, big shepherds.
14. Rubie’s Toy Story Rex Pet Costume
4.3 stars · 1,257 ratings · around $36 · sizes M–XXXL
Officially licensed Rex, sized medium through XXXL. This is the version that actually fits a big dog instead of stopping at 20 pounds. It is the priciest pick here, but it is a full character costume rather than a printed shirt, and it is the one that wins costume contests.
Best for: big dogs, big energy, big costume-contest ambitions.
15. Wiz BBQT Big Dog Vampire Cape
4.6 stars · 207 ratings · around $10 · built for XL breeds
Made specifically for Great Danes, German shepherds and other genuinely large dogs — the listing names them, which is rarer than it should be. A cape is also the most forgiving thing you can put on a big dog: it drapes rather than fits, so there is almost no way to size it wrong. Smallest review count in this post at 207, so it is newer than the rest, but the 4.6 average is holding.
Best for: enormous dogs and last-minute panic.
Three measurements, five safety rules. One page, print it before you shop.
Dog Costume Safety: Five Rules I Never Break
- Do a dress rehearsal. Put the costume on for five minutes a few days early, with treats. If your dog freezes, tucks their tail, or tries to shake it off, that is a no — and that is fine.
- Never leave a costumed dog unsupervised. Straps snag, dogs chew, and a costume left on alone is a hazard.
- Check for chokeable parts. Buttons, googly eyes, bells and dangling bits get eaten. Cut them off if you have a chewer.
- Watch for overheating. A full-body costume plus a warm night plus an excited dog is a bad combination. Short sessions only.
- Keep vision, hearing and movement clear. Nothing over the eyes, nothing pinning the ears, nothing that changes how they walk.
None of that is me being precious about it — the ASPCA says the same thing: try the costume on before the big night, make sure it does not limit movement, sight or breathing, and check it for small or dangling pieces that could be chewed off.
And if your dog is genuinely miserable in clothes? A Halloween bandana and a good treat is a complete costume. Nobody is grading you.
Dog Halloween Costume FAQ
What size dog costume should I buy?
Measure your dog’s neck, chest and back length, then match those numbers to the specific brand’s size chart. Never buy by breed name or by weight alone — costume sizing varies wildly between brands. When you are between two sizes, always go up.
Are dog Halloween costumes safe?
They are safe when they fit properly, do not restrict vision or movement, have no small parts your dog can swallow, and are only worn while you are supervising. Take the costume off if your dog is panting heavily, freezing in place, or trying to get out of it.
What is the most popular dog Halloween costume?
Pumpkin takes the top spot most years, followed by hot dog, bat, bumblebee and spider. Superhero and ghost costumes round out the top tier.
Where can I find dog costumes for large dogs?
Look for listings that explicitly offer XL, XXL or XXXL — Rubie’s sizes up further than most, and the Wonder Woman costume above goes to XXXL. Cape and wing styles also work better on big dogs than fitted full-body suits, because they drape rather than needing an exact fit.
How much should I spend on a dog costume?
Most quality dog Halloween costumes land between $10 and $28. Licensed character costumes for large dogs run $25 to $40. Anything under $8 is usually thin fabric that will not survive a second season — the exception is accessories like wings and capes, which are simple enough to be cheap and still good.
When should I buy a dog Halloween costume?
Late September to the first week of October. Buy earlier than you think you need to, because the popular sizes go first — extra-small and extra-large both sell out well before Halloween, and those are exactly the two hardest sizes to substitute. Ordering early also leaves room to exchange it if the fit is wrong, which is the single most common reason a costume never gets worn. If you are shopping the week of Halloween, stick to capes, bandanas and wing harnesses, since those adjust rather than needing an exact fit.
The Bottom Line
Of all the dog Halloween costumes above, here is the safest bet in each category. Small dogs, grab the Fitwarm pumpkin dress. Medium dogs, the Kuoser tuxedo is the highest-rated thing here and you will use it all year. Large dogs, the bat wings are cheap, comfortable and nearly impossible to size wrong.
Measure your dog tonight, order this week, and do a five-minute dress rehearsal before the big day. Future you — the one not panic-shopping on October 30th — will be very grateful.
