Find Halloween Dog Costumes, Wigs & Accessories
Dress your pup for a frightfully fun night with the selection of dog Halloween costumes at Petco. Styles run from cutesy to genuinely spooky, and the size range covers everything from the smallest lap dog to XL breeds who need real room to move. Just don't be surprised when your dog takes home best dressed.
Getting the size right
Run a measuring tape around your dog's neck, chest and back length, then match those numbers to the size chart rather than guessing from breed. A costume should never restrict movement, block vision or cover the mouth, and anything with small dangling pieces is worth skipping for dogs who chew. Try the costume on a few days early so your pup can get used to it. Many Petco stores stock seasonal costumes, so you can check availability near you and try before Halloween arrives.
Frequently Asked Questions
-
Measure your dog's neck circumference, chest girth and back length from collar to tail base, then match those to the size chart. Don't size by breed, since two dogs of the same breed can need different sizes. If your dog falls between sizes, go up, since a snug costume restricts movement.
-
Yes, provided the costume fits well and doesn't restrict movement, vision or breathing. Skip anything with small parts your dog could chew off, and check that nothing presses on the throat. Supervise your dog while they're wearing it, and take it off if they seem anxious or are trying to remove it.
-
Large and XL dogs do best in costumes with adjustable straps and open chest designs that don't restrict their stride. Simple styles like capes, bandanas and hooded outfits tend to fit big breeds better than structured full body costumes. Check the size chart for XL and XXL options rather than assuming a large will fit.
