America’s #1 Dog Halloween Costume: Chucky

PetLabCo. analyzed nationwide Google search data to reveal the top ten most searched-for Halloween costumes for dogs, to see which characters proved the most popular for our furry friends – and which costumes may be better for those seeking more originality.

Even though some of us prefer cute costumes over spooky ones, it turns out that most dog owners are fans of classic horror icons, with the infamous red-headed Chucky coming out as the most popular costume overall. This may be due to the long-standing nature of the film franchise, which started in 1988 with Child’s Play and is still going strong, with the latest film released in 2019.

Terrifyingly Tasty Howl-oween Treats for Dogs

If you’re taking your pup to a costume party, it’s a good idea to go prepared with a dog-friendly Halloween treat or two, as they won’t be able to partake in the human candy that will no doubt have them puppy dog-eyed and drooling.

PetLabCo. offers a wide range of treats for dogs, from delicious Beef Jerky to mouthwatering Beef Liver Bites.

PetLabCo. Advice: Having a Happy, Pup-Friendly Halloween

While it’s important to keep in mind which costumes are particularly popular for pets, it’s also key to consider your dog’s comfort when including them in your Halloween festivities.

Co-founder and CEO of PetLab Co., Christopher Masanto has this advice for loving pet owners looking to spruce up their pet’s spooky look:

“We all love seeing how adorable our dogs look dressed up in their costumes, and its great owners think of their pets as part of the family. However, some dogs may not feel the same love for their costumes as we do. Dressing up may even cause some of our pets to become stressed and anxious, especially if they’ve never worn anything similar before. They’ll be less spooky, and more spooked.” 

“If you’re planning to dress up your furry friend this year, there are some signs of stress you may want to look out for, including whimpering, excessive panting, rubbing, or scratching. This may be caused by discomfort associated with parts of their costume or sensory overload caused by a new sensation. If you notice these signs, it may be time to lose the outfit and take your pooch back home.”  

“To help calm your dog if they’re feeling uneasy, make sure they have an easily accessible safe place. This may be the room they sleep in or cuddled up on the couch under a blanket. You’ll want to ensure the place is quiet to allow your dog time to return to its usual happy state. We love Halloween, but we love our pets too, and this way, we can ensure a safe and enjoyable Halloween for everyone!”
