What size dog does the medium fit?

Medium sizes generally fit dogs of average build, but sizing varies by brand. Check the size chart on the product page and measure your dog's chest and neck for the best fit.

Is this costume comfortable for dogs to wear?

Comfort depends on the individual dog. Choose a snug but not tight fit, allow free movement of legs and neck, and keep wear time short, especially the first time.

Can I use this costume for more than Halloween?

Yes. It works for themed parties, costume contests, birthdays, and photo shoots throughout the year, including National Postal Worker or pet-themed events.

Who Should Buy This?

This costume suits owners of medium-sized dogs who want a lighthearted, recognizable outfit without a complicated setup. It is a good fit for Halloween parades, pet costume contests, and holiday photo cards. It also works well for dogs that tolerate wearing clothes, and it can be a funny pairing with a family member dressed as a delivery driver.

Buying Tip

Measure your dog's chest, neck, and back length before you order, then compare the numbers to the size chart rather than relying on the size label alone. Let your dog wear the costume for a few minutes indoors with treats before the big day so they get used to it. Always supervise your dog while it is dressed up and remove the costume if it seems stressed.
