The expanded shape is made for medium and large dogs, and adjustable straps help secure it for festive wear.

What does the GUDELAK spider dog costume look like?

It turns a dog into a green-and-black, monster-inspired spider with eight oversized furry legs. The expanded silhouette makes the spider shape prominent, giving your pet a playful costume look for Halloween celebrations and themed photographs. Its bold colors and raised legs create the character effect without relying on a printed design alone.

• Made for Halloween parties, pet parades and cosplay events.
• Also suited to family gatherings and creative photoshoots.

How do I choose the right fit for my dog?

Measure your dog’s neck and chest and compare those measurements with the costume’s stated ranges: the neck fits 18–31.5 inches (45.7–80 cm), and the chest fits 28.4–45.5 inches (72.1–115.6 cm). Adjustable self-adhesive straps allow you to secure the outfit, while its flexible construction is intended to let your dog walk and play during celebrations. The size range is designed for medium and large breeds.

• Use both neck and chest measurements when assessing fit.
• The oversized spider shape is created for a dramatic costume appearance.

What do the LED lights add?

The costume has 64 bright LED lights and multiple lighting modes for different festive effects. They give the spider outfit a glow for evening walks, outdoor events and Halloween gatherings, and add a visible light effect in photos after dark. Choose a lighting mode to suit the occasion.

• Light effects are part of the costume design.
• Useful for evening celebrations and themed photo opportunities.

What is the costume made from?

GUDELAK is made from felt that is described as durable and odor-free. The material helps maintain the oversized spider structure, while its lightweight, flexible construction supports movement. The furry legs are designed to stay upright, helping preserve the spider silhouette as your dog walks and plays.

• Felt forms the costume’s oversized shape.
• Flexible construction is intended for movement during holiday activities.

This costume suits medium and large dogs whose measurements fall within its neck and chest ranges, and owners looking for a playful Halloween look with built-in lighting. It is made for festive dress-up, outings and photos rather than an everyday outfit. Its felt spider shape, adjustable straps and LED effects bring the costume’s character together in one design.
