BT Bear Dog Halloween Pumpkin Costume – £14.99

A pumpkin is a classic Halloween costume, and this adorable plushie version is the perfect adorable pick for a party or photoshoot. Although it’s available in sizes small to XL, reviews suggest this is better suited to small breeds – or even your cat, if you can wrestle them into it! It has an adjustable velcro fastening around the neck and elastic leg straps to keep your pet comfy, and features a squishy round body with a hood to complete the look.

It’s easy to slip on and off, although it only comes in one size measuring 30cm x 25cm.

Stegosaurus Dog Costume – £31.99

This might be the most expensive costume on our list, but it’s also the most elaborate.

It comes in sizes XS to XL, although currently the XS and small sizes are both out of stock.

Halloween Cowboy Pet Costume – £8.99

With sizes spanning a small to an XL, this costume can fit both cats and dogs making it the perfect pick for a multi-pet household.
