In honor of National Dog Week and pet-obsessed people everywhere, zulily has unveiled the top pet costumes for 2018 and they are sure to bring a smile to any ghoulish bash or trick-or-treating adventure. Looks like a growing percentage of Americans are feeling like Fido should be included in their upcoming Halloween festivities!

Almost all – 84% – of millennials get separation anxiety when away from their fur baby for even a short period of time. Hence the need for Sparky’s coordinating costume for trick or treating.

So what’s trending this Halloween season?

Online retailer zulily has unveiled the best-selling pet costumes for this All Hallows’ Eve: pet owners are dressing up their dogs and cats as lions, pandas, and characters from Star Wars (Ewoks and Princess Leia top the list).

After that, whimsical costumes are also trending: unicorns, pirates, and even the flying monkey from The Wizard of Oz.

Check out these styles and more on zulily.com – and we can’t wait to see your pets dressed up this Halloween!
