Helpful Halloween Tips
Questions? We Can Help
Measure your pet's neck, chest, and back length, then compare those measurements with the size chart on the product page. If your pet is between sizes, sizing up usually provides more comfort and mobility.
Choose a harness-friendly costume with clear access to the harness D-ring. Always attach the leash to your pet's actual collar or harness, not to a decorative costume piece.
Try lightweight accessories such as bandanas, bow ties, collars, hats, or capes. Introduce new items gradually and keep early wear sessions short and positive.
Order early to secure your preferred costume and size. Check the shipping estimate at checkout for an estimated delivery date based on your address.
Costumes must be unworn, hair-free, and returned with their original packaging and all included pieces. Halloween costumes cannot be returned after October 25.
Celebrate spooky season with Halloween costumes, toys, treats, and accessories for dogs and cats. BaxterBoo carries pet Halloween essentials for every personality, including easy-on costumes, character outfits, funny costumes, seasonal plush toys, and fall-inspired treats.
Before choosing a costume, measure your pet and check the product's individual size chart. Pets that prefer something lightweight can still join the fun with festive bandanas, bow ties, hats, shirts, and collars. Complete the celebration with Halloween dog toys, cat toys, and pet-friendly treats for parties, photos, or a cozy night at home.
