A DIY dog costume beats a shop-bought one for two reasons that have nothing to do with money. You can build it around your own dog's shape, and you can stop the moment they have had enough, which is harder to do when you have already paid for something. Everything below can be made at a kitchen table.

Some of these are ours and some come from crafters we admire, and every one is credited so you can go and get the full instructions. If your dog would rather skip the whole thing, our shop-bought Halloween costume picks are the low-effort route.

The easiest homemade dog costumes start from something your dog already wears comfortably. A bandana, a harness or a plain t-shirt gives you a base that fits, so all you are adding is felt, fabric paint or a few glued-on shapes. No-sew builds using fabric glue or iron-on hem tape hold up perfectly well for one evening. Whatever you make, it needs to leave your dog able to see, hear, breathe, pant and walk normally, with nothing tight around the neck or chest and no small pieces they could chew off and swallow.

9 Homemade Dog Halloween Costumes to Try

Nine ideas, roughly easiest first. Each one lists what it is built from and how fiddly it is, so you can match the project to the evening you actually have.

No-Sew Pumpkin Mask and Bandana Set

Made from:

orange felt, fabric glue, a bandana.

Difficulty:

easiest on the list.

This is our own tutorial and the one we would start a nervous dog on, because the mask sits on the bandana rather than on the face. There is no elastic behind the ears and nothing across the eyes, so a dog who tolerates a bandana will tolerate this. It photographs far better than it has any right to for the effort involved.

Simple No-Sew Halloween Dog Bandana

Made from:

printed cotton, hem tape or fabric glue.

Difficulty:

easiest on the list.

The bare minimum, and genuinely enough. A themed bandana reads as a costume in a photo, costs almost nothing, and a dog who hates dressing up will not notice they are wearing it. If your dog has form for wriggling out of anything more ambitious, make this and call it done, and our no-sew dog bandana tutorial covers making the bandana itself. Full tutorial by CTRL + CURATE.

No-Sew Bat or Dragon Costume

Made from:

felt wings, elastic or a harness base.

Difficulty:

easy.

Two shapes cut from felt and attached over the shoulders, which is about as much costume as most dogs will accept. Wings sit where a harness sits, so they interfere with movement less than anything that wraps the body. Worth attaching them to a harness your dog already wears rather than adding new straps. Full tutorial by Lia Griffith.

Spider Dog Costume

Made from:

black fabric, stuffing for the legs.

Difficulty:

easy to moderate.

A classic for a reason, and one of the few costumes that looks better on a bigger dog. The extra legs sit along the back and move as your dog moves, which is the whole effect. Keep the legs light and soft: anything with wire in it can poke, and anything heavy will slide sideways within ten minutes. Full costume by Martha Stewart.

Latte Dog Costume

Made from:

cardboard or felt cup sleeve, white fluff for the foam.

Difficulty:

moderate.

Firmly in the funny-rather-than-frightening category, and a good pick if your Halloween plans involve a party rather than a dark street. It suits small to medium dogs, since the shape relies on the cup sitting neatly around the body. Build the cup from something soft if your dog is going to be wearing it for more than a photo.

Dog Martini Costume

Made from:

felt or card glass shape, green olive detail.

Difficulty:

moderate.

The other half of a very good couples costume if you are going as the bartender. Like the latte, this one is built around a shape sitting on the dog rather than wrapping them, which is generally the more comfortable approach. Check the shape does not block the shoulders when they trot. Full tutorial by Brit + Co.

Pineapple Dog Costume

Made from:

yellow fabric, green felt for the leaves.

Difficulty:

moderate.

Proof that a dog costume does not have to be spooky to work on Halloween. The leaves do most of the visual work here, so if you are short on time, a green felt crown on the collar and a plain yellow t-shirt gets you most of the way. Yellow also photographs well after dark, which matters more than people expect. Full tutorial by Brit + Co.

Rainbow Cotton Candy Costume

Made from:

pastel tulle, a harness or vest base.

Difficulty:

moderate, but forgiving.

Tulle is the friendliest material on this list to work with, because it hides every mistake and needs no hemming. It is also light and airy, so this is one of the better options for a dog who overheats easily. The matching human version is the point, if that is your sort of thing. Full tutorial by Brite and Bubbly.

Matching Dog and Owner Scarecrow Costumes

Made from:

plaid fabric, raffia or straw trim, a hat.

Difficulty:

the most involved here.

The biggest build on this list and the one that wins competitions. Worth knowing before you start: loose straw and raffia are exactly the sort of thing a bored dog will pull off and eat, so keep the trim well secured and keep an eye on it. Best suited to a calm, patient dog who genuinely does not mind dressing up. Full tutorial by Aleene's.

Easy No-Sew Dog Costume Ideas

If the nine above are more project than you have time for, these four take under half an hour and use things you probably already own. None of them require a sewing machine, and if you are decorating for a party too, our dog pinata tutorial is the same kind of afternoon.

The felt-shape bandana. Cut a ghost, a bat or a pumpkin from felt and glue it onto a bandana your dog already wears. Five minutes, no fitting required, and it works on any dog of any size.

The skeleton t-shirt. A plain black t-shirt in your dog's size plus white fabric paint. Lay the shirt flat, paint a simple ribcage down the front, and let it dry overnight. It reads clearly from a distance, which is more than most homemade costumes manage.

The harness upgrade. Whatever harness your dog walks in already fits properly, which is half the battle. Add felt wings, a felt shell, or a small cape fastened to the back ring. Nothing new goes around the neck or chest, so there is nothing new to rub.

The collar accessory. A tiny witch's hat, a bow tie or a felt flower clipped to the collar. This is the version for dogs who genuinely hate costumes, and it still gives you the photograph. Never leave anything clipped to a collar on an unsupervised dog.

Costume Safety and Fit for Dogs

This is the part most costume roundups skip, and it is the part that decides whether Halloween is fun or a trip to the emergency vet.

What to check before the costume goes on

Run through the same list every time. Can your dog see in every direction, with nothing across the eyes? Can they hear, with nothing covering the ears? Can they open their mouth fully and pant, which is how they cool down? Can they walk, sit and squat normally, with nothing between the back legs? Is anything tight around the neck, chest or belly?

Then check for anything chewable. Buttons, googly eyes, pom-poms, loose straw and glued-on felt shapes are all swallowable, and a fabric blockage is major surgery. If a piece can be pulled off, assume it will be. Never leave a costumed dog alone, not even for the length of a phone call, and take the whole thing off before bed. Our Halloween pet safety tips cover the rest of the evening, including the doorbell and the chocolate.

Getting your dog comfortable wearing it

Do not let Halloween night be the first time your dog sees the costume. Put it on for thirty seconds a few days beforehand, pay them well, and take it off before they ask you to. Build up from there.

Then read them honestly, because dogs are polite about this and it is easy to miss. A dog who is uncomfortable will freeze and stop moving, tuck their tail, flatten their ears, lick their lips, yawn when nothing is tiring, show the whites of their eyes, or try to shake the thing off. A dog who is fine will keep moving normally and take a treat without hesitating. If you get the first list, take it off. A bandana and a good photo is a perfectly respectable Halloween.

Once the costume comes off, the celebrating can continue with our no-bake pumpkin Halloween treats, and if there is a new arrival to name before October, our list of Halloween dog names runs to 263 of them.
