When the relationship is going strong, even Halloween turns into a team sport. You’ve got your favorite person by your side, a mischievous pup who’s practically family, and a holiday that practically begs for coordinated chaos.
If there was ever a moment to turn heads at the pumpkin patch or make the group chat jealous, this is it.
Matching Halloween costumes aren’t just for couples looking to win contests. They’re for those who know that a little bit of silly fun builds serious memories.
Add a dog to the mix, and suddenly you’ve got a trio that can stop traffic… or at least steal the spotlight at any Halloween hangout.
Whether you’re a new couple still learning each other’s snack preferences or you’ve already picked out dog names together years ago, dressing up with your pet adds a special kind of magic.
It’s equal parts adorable and a little bit smug, in the best way.
1. Hot Dog Stand Trio
Nothing sizzles like a couple running a “hot dog” stand… with the actual hot dog in the middle. Dress up as food vendors while your pup takes center stage in a fluffy bun and mustard outfit.
It’s punny, it’s charming, and it’s just enough chaos to spark compliments all night.
2. Ash, Misty & Pikachu
The ultimate throwback for any millennial love story. One of you is Ash, one is Misty, and your dog? Naturally, Pikachu. This trio screams nostalgic devotion.
Bonus points if your pup is already known to bolt like a lightning bolt when the leash comes off.
3. Up – Carl, Russell & Dug
Wholesome, heartfelt, and just the right level of quirky. One partner dons the iconic glasses and bowtie as Carl, the other becomes the lovable Scout Russell, and your dog gets to be everyone’s favorite squirrel-chasing golden retriever, Dug. Balloons optional, but highly encouraged.
4. Addams Family with Wednesday and Pugsley Pups
Goth love is real love. This eerie, elegant combo turns heads with Morticia and Gomez perfection, while your dogs double as Wednesday and Pugsley.
It’s timeless, theatrical, and a great excuse to wear all black, because, let’s be honest, that’s the real couple uniform.
5. Velma, Shaggy & Scooby-Doo
Zoinks! A perfect match for playful couples and even goofier dogs. Dress as Velma and Shaggy (mystery-solving energy encouraged), while your furry friend takes on the role of Scooby-Doo.

7. Princess Leia, Han Solo & Chewbacca
If you’re already a strong pair, why not go galactic? The classic Star Wars trio gets a fluffy twist here.

8. The Flintstones & Dino
Stone-age charm with just the right hint of chaos. Dress up as Fred and Wilma, while your dog takes on the role of Dino, complete with a giant bone accessory.
This one’s perfect for couples who love to keep things playful and for dogs who love being the center of attention.
9. Breaking Bad with the Pup
Matching yellow hazmat suits? Check. A serious attitude and a few mock bottles of “product”? Even better. Let your dog join the operation in a mini suit and safety goggles.
This costume trio is for couples who love dark humor and sharper edges, without actually breaking anything bad.
10. Jurassic Park with Velociraptors
