Dog Halloween Costumes: common questions

Are Halloween costumes safe for dogs?

Choose costumes that leave the eyes, nose, mouth and ears free, have no small chewable parts and fasten with velcro or snaps. Never leave a dog alone in a costume.

How do I pick a costume size?

Measure your dog's chest at the widest point and add about 2 inches. If your dog is between sizes, size up – costumes are worn over the fur for short periods.

Will my costume arrive before Halloween?

Check the order-by dates at the top of this page. Styles from our US warehouse arrive fastest; styles marked "May arrive after Halloween" are best ordered for next year.
