Small Dog Halloween Costumes: Sizing, Fit, and Picks
Small dog Halloween costumes sized by chest girth: how to measure for XS and S, eight Chewy-stocked picks with sizes stocked and wear-time ratings, and safety rules for small dogs.

The best small dog Halloween costumes are the ones sized by chest girth, not by the weight printed on the package. A 7-pound Chihuahua and a 7-pound Yorkie can need different sizes, and a costume that is one size too big on a toy breed slides sideways, drags at the back and pushes a hood over the eyes within minutes.
This guide covers small dog Halloween costumes for dogs under about 20 pounds: how to measure for XS and S, which eight Chewy-stocked costumes fit narrow chests and short backs, which sizes each one is actually stocked in, how long a small dog can comfortably wear one, and when a hat or bandana is the smarter choice.

Small Dog Halloween Costumes at a Glance
- 1Measure chest girth first; weight is only a rough guide for small dogs
- 2Frisco Hotdog is the best full suit for long, short-legged backs in XS
- 3Keep costume sessions short and remove the costume at the first stress signs
- 4A mane leaves the body uncovered but still requires comfortable headwear fit.
- 5A dog that dislikes a body costume may also dislike a hat; dressing up is optional.
- 6Use the exact product's measurements rather than XS/S weight assumptions.
What should you dress your dog in for Halloween? For small dogs, compare a mane, hat or body costume using the exact product chart and your dog's response to the complete outfit. Check the face, legs and tail for clearance. Lower weight or less body coverage does not establish which construction your dog will accept.
How we chose these picks:
- Small-dog sizing: each costume is stocked in XS, S or an XS/S accessory size suited to toy and small breeds under about 20 pounds.
- Fit on small frames: we favored designs that fasten under the chest, leave the face open and are unlikely to slip over the eyes or drag behind a short back.
- Safety: no small detachable trim, nothing tight at the throat, in line with AVMA and ASPCA costume guidance.
- Availability: every pick was stocked at Chewy when we reviewed the listings.
- Method: this is expert analysis of Chewy product listings, construction and published size charts; we did not test these costumes hands-on.
The table compares construction, catalog size labels and the main fit check for each costume. It does not predict how long an individual dog will tolerate wearing one.
| Costume | Construction | Recorded catalog labels | Sizing check (XS/S) | Design choice | Main fit check |
|---|---|---|---|---|---|
| Frisco Hotdog Dog & Cat Costume | Bun body piece | XS, L, XXL | Chest girth vs Chewy chart | Food costume with a bun body piece | Body wrap and leg clearance |
| Frisco Lion Mane Dog & Cat Costume | Mane only | XS, S, M, L, XL | Fits by neck | Mane without body coverage | Mane stays clear of eyes and ears |
| Pumpkin Dog & Cat Costume Frisco | Stuffed body and separate cap | S, M, L | Chest girth vs Chewy chart | Round pumpkin silhouette | Body length, closures and separate cap |
| Bumble Bee Dog & Cat Costume Frisco | Body with back wings and separate antenna headpiece | S, M, L, XXL | Chest girth vs Chewy chart | Striped bee with wings | Body fastening, wings and headwear |
| Frisco Octopus Dog & Cat Costume | Headpiece with tentacles, earholes and chin strap | S, XXL | Chin circumference vs the exact Chewy chart | Octopus headpiece | Chin strap, earholes and tentacles stay clear of the face and mouth |
| Frisco Duck Dog & Cat Costume | Yellow bodice and separate headpiece | S, L | Chest girth vs Chewy chart | Two-piece duck character | Body piece and headwear fit separately |
| Rubie's Costume Company Pooh Dog Costume | Hooded shirt | Small (Rubie's chart) | Check Rubie's chart | Pooh character outfit | Body length, openings and headwear |
| Frisco Pumpkin Dog & Cat Hat Costume | Plush headpiece | XS/S | Fits by neck | Pumpkin headwear without a body suit | Comfortable fastening and clear eyes and ears |
Each brand prints its own size chart, so measure your dog and compare those numbers against the chart on each Chewy listing before you order.
The table records labels found in the retained catalog sample. It is not a complete size range or a live stock list: the Hotdog and Octopus product pages list sizes beyond that sample. Check the selected product's current options and exact chart before ordering.
How to Size an XS or S Dog Costume
Small dogs should be sized by chest girth rather than weight because weight hides body shape. A deep-chested toy breed and a fine-boned one at the same weight can differ noticeably around the ribs, and on a dog this small that difference can mean a full size.
How to measure a small dog for a costume:
- Use a soft fabric tape measure, not a metal one, and stand your dog squarely on all four feet.
- Measure over the coat as it normally lies; do not flatten the fur.
- Chest girth: wrap the tape around the widest part of the ribcage, just behind the front legs. This is the number that decides the size.
- Neck girth: measure around the base of the neck where a collar sits. This matters most for hats, manes and hoods.
- Back length: measure along the spine from the base of the neck, at the collar line, to the base of the tail. A costume longer than this drags or bunches over the tail.
- Measure chest girth, neck girth and back length using the exact product chart's instructions. Do not add an allowance unless that chart directs you to.
XS and S are not standard weight bands. A dog under 7 pounds does not automatically need XS, and an 8–15-pound dog does not automatically need S. Compare every required measurement with the selected product's chart, including for accessories.
| Check | How to choose |
|---|---|
| XS or S body costume | Compare chest, neck and back measurements with the exact chart. |
| Combined XS/S label | Check the stated measurement range; do not infer a weight range. |
| Headwear | Check its specified measurements and clearance around the face. |
| Measurements span sizes | Choose another cut if no size accommodates them all. |
If no size accommodates every required measurement, choose another cut. On a narrow chest, check that the body piece stays centered as your dog walks and turns, with its fastenings in the intended positions. Do not use pins or an improvised fold to compensate for excess length.
What dog costume is easiest for dogs to wear? Choose a style your dog accepts and can move normally in. A mane or hat leaves the body uncovered but needs its own face-clearance check. A bun or tabard needs secure body fastenings; a hooded suit needs clear vision and correctly placed openings. No construction is easiest for every small dog.
Rubie's Costume Company sizing runs on its own chart, so a Rubie's Small and a Frisco S are not interchangeable. Measure once, write the three numbers down and check each brand's chart separately.
The Best Small Dog Halloween Costumes
What are some good Halloween costumes for small dogs? The direct answer: costumes that fasten under the chest, leave the face open and stay light, like a lion mane, a hotdog bun or a pumpkin hat. These eight selected products appeared in the retained catalog. Each entry identifies the product and its recorded size labels, with fit checks for narrow chests, short backs and face clearance. Confirm the current selection for the desired variant before ordering.
For a dated pet-costume popularity benchmark, the National Retail Federation's annual Halloween survey reported pumpkin first at 11 percent in its 2023 survey, followed by hot dog at 7 percent, bat at 4 percent and bumblebee at 3 percent. These are historical pet-costume figures, not a current small-dog ranking. The Pumpkin, Hotdog, Bumble Bee and pumpkin hat below offer several of those familiar looks. Check each one's measurements and keep decorative wings or legs clear of the feet and mouth. For a roundup across dog sizes, see our guide to the best dog Halloween costumes.
Frisco Hotdog Dog & Cat Costume
The Frisco Hotdog Dog & Cat Costume is the classic choice for a Miniature Dachshund, and the joke lands best on a long, low dog. The bun sits on a short back without dragging when the size is right, and the face stays completely clear.
XS, L and XXL appear in the retained catalog sample, but the product page also lists S and M. Compare neck, chest and back measurements with the exact selected size, then check that the bun does not bunch or overhang enough to interfere with movement.
Stocked XS, L and XXL; the bun sits on a short back without dragging.

Frisco Lion Mane Dog & Cat Costume
The Frisco Lion Mane leaves the body and legs uncovered. Check that it stays clear of the eyes and ears, and use it only if your dog comfortably accepts headwear.
It is stocked in XS, S, M, L and XL, the widest size run here. Fit it by neck girth, and check that the fringe does not fall into the eyes on flat-faced breeds like Shih Tzus and Pugs. A Pet Krewe lion mane is a close alternative if the Frisco size you need sells out.
Stocked XS, S, M, L and XL; highest wear-time rating.

Pumpkin Dog & Cat Costume Frisco
The Pumpkin Dog & Cat Costume Frisco pairs a stuffed orange body with a separate cap. Check the body's length and closures, then assess the cap independently for a clear face and comfortable fit.
S, M and L appear in the retained catalog sample. Compare the exact chart with your dog's measurements and check that the body stays centered without restricting movement; breed and body shape alone do not establish fit.
Stocked S, M and L; soft and open-faced.

Bumble Bee Dog & Cat Costume Frisco
The Bumble Bee Dog & Cat Costume Frisco has a body piece with back wings and a separate antenna headpiece. Check the neck and belly fastenings, wing clearance and headpiece fit, including whether your dog can reach or chew any part.
Treat the bee costume as a costume, not as a substitute for suitable cold-weather protection.
Stocked S, M, L and XXL; wings sit on the back.

Frisco Octopus Dog & Cat Costume
The Frisco Octopus Dog & Cat Costume is a headpiece with soft tentacles, earholes and a chin strap. It creates an octopus look without a body suit, but still requires a comfortable headwear fit.
S and XXL appear in the retained catalog sample; they are not the complete size range. Use the product's chin-circumference chart, then check the earholes, strap and tentacles. Remove the headpiece if it slips toward the face, can be chewed or prompts pawing.
Stocked S and XXL; the cheapest full costume in the set.

Frisco Duck Dog & Cat Costume
Check the duck costume's body piece and separate headpiece independently. Remove either piece if your dog paws at it or changes their normal movement.
S and L appear in the retained catalog sample. The yellow bodice and separate headpiece have their own fastenings, so check both fits and keep the headpiece clear of the eyes and nose.
Stocked S and L; hood must not slip over the eyes.

Rubie's Costume Company Pooh Dog Costume
Check the Pooh outfit's body length, openings and headwear against your dog's measurements and comfort.
The listing checked October 5, 2026 was Small. Compare the exact Rubie's chart with all three measurements and check the headwear separately. If it will not stay clear of the eyes, nose and mouth during movement, do not rely on folding it back to correct the fit. For a matching look, pair Pooh with a human Christopher Robin outfit; our dog and owner Halloween costumes guide has more matching ideas.
Rubie's Small; hood-style, medium wear-time rating.

Frisco Pumpkin Dog & Cat Hat Costume
A hat is an option only for a dog that accepts headwear. Refusing a body costume does not mean the dog will be comfortable with something on their head.
A hat still needs supervision: the strap should be snug enough to stay put but loose enough to fit a finger underneath. For an even simpler step down, the Frisco Trick or Treat Dog & Cat Bandana Costume ties on like a collar.
Hat only, under ten dollars; the trick-or-treat bandana is the step down.

For more laughs in tiny sizes, the Frisco Taco Dog & Cat Costume and the Frisco Prisoner costume both come in XS. Have a bigger dog in the house too? Our large dog Halloween costumes guide covers deep chests and long backs.
Where to Buy Small Dog Halloween Costumes
Most people who shop small dog Halloween costumes run into the same problem: XS can be hard to find. Chewy is the most reliable place to find Frisco and Rubie's costumes in XS and S, and its product pages show which sizes are still available, so you can check stock before you commit to a design. Each costume's product page lists which sizes are stocked right now, so you can find out whether XS has sold out without having to click through every style one by one.
Does Walmart have dog costumes? Yes, Walmart carries seasonal dog costumes in stores and online, though small-size selection varies by location. Searching for small dog Halloween costumes nearby usually turns up Walmart, Target or a local pet store, so call ahead and ask for XS stock by chest measurement rather than by weight.
- Measure chest girth, neck and back length before buying anywhere; XS and S charts differ by brand, and a costume that is snug at the chest will not get worn.
Does Dollar Tree have dog Halloween costumes? We have not verified its current pet-costume selection. Check the current listing or local store for an item intended for pets, then compare its measurements and fastening with your dog. Do not assume a low price or a small-looking accessory establishes fit.
Here is how the main retailers compare for small sizes:
- Chewy: the widest Frisco and Rubie's range, with available sizes shown on each product page.
- Amazon: small dog Halloween costumes from many brands, but sizing charts vary widely, so check chest girth on every listing.
- Walmart and Target: check current pickup or delivery options and the exact costume's size chart before planning a same-day purchase.
- Dollar Tree: current pet-costume availability is unverified; check the item, measurements and fastening rather than assuming it is the cheapest suitable option.
For a lower-cost option, compare the Frisco Trick or Treat Dog & Cat Bandana Costume and the Frisco Lion Mane in Small with the body costumes above. Check current prices, the exact measurements and whether your dog accepts that type of accessory.
DIY Costumes for Small Dogs
DIY small dog Halloween costumes work best when they stay small: a felt cape clipped to a harness, a bandana with iron-on letters or a soft headband with felt ears. These shapes add almost no weight and nothing that covers the face.
Skip anything glued on with beads, buttons or loose trim, since small dogs can chew those off and swallow them. For a full list of homemade ideas, see Petful's dog costume ideas guide.
Safety and Wear Time for Small Dogs
- The AVMA and ASPCA advise that a costume must not restrict movement, breathing, hearing or vision, and must have no small detachable parts a dog could chew off and swallow. Keep a short wear time and supervise the whole time. Watch for stress signs such as a tucked tail, flattened ears, lip licking, yawning, freezing or trying to back out of the costume, and remove it right away. Cold tolerance varies with coat, body condition, activity and health. A costume is not a substitute for suitable cold-weather protection; keep the activity indoors if your dog is uncomfortable outside.
The AVMA's Halloween safety tips recommend trying a costume on well before the holiday and skipping it entirely if your pet seems stressed. The ASPCA gives similar guidance on fit and on choking hazards from small parts.
Cold tolerance varies with coat, body condition, activity and health; a 10-pound cutoff does not establish it. Check the weather and your dog's behavior rather than using a preset outdoor duration. A thin costume is not a substitute for suitable cold-weather protection. Move indoors if your dog appears uncomfortable outside, and remove any costume that causes distress.
Reconsider the outfit or the outdoor plan when any of these apply. A headpiece, hat or bandana is an alternative only if it fits and your dog accepts it:
- Your dog freezes, sits down or tries to back out the first time you hold up a suit.
- The evening will be cold and the costume would sit over, or replace, a warm sweater.
- A hood, fringe or fastening crowds the eyes, nose or mouth, including on a flat-faced dog.
- The weather or your dog's behavior suggests the outdoor activity is uncomfortable.
Before you head out in any costume, run a quick check:
- The costume fastens without pressing on the throat.
- Your dog can see, sit, lie down, walk and relieve itself normally.
- Nothing dangles that can be chewed loose.
- You can remove the costume quickly if your dog starts to shiver or shows stress.

Small Dog Halloween Costume FAQ
Weight alone cannot establish the size for a 5-pound dog. Measure chest, neck and back and compare them with the exact costume chart. Check headwear measurements separately.
Compare the exact costume's measurements, fastening design, included pieces and return terms. Price alone does not establish whether it will fit or stay in place.
Use only a product intended for cats as well as dogs and compare the cat's measurements with its chart. An XS label does not establish fit, and a hat is not automatically more acceptable than a body costume.
There is no fixed duration that suits every small dog. Try the outfit before Halloween and supervise throughout. Remove it if your dog shows distress, tries to wriggle out or changes its normal movement; move indoors if the outdoor conditions are uncomfortable.
Only if the puppy accepts it and the exact costume fits. Measure close to Halloween rather than relying on an earlier size, check for loose parts the puppy could chew off and supervise throughout. Remove the outfit if it affects normal behavior or movement.
