WHY DOG OWNERS NOTICE IT
Built for the scroll-stopping reveal.
A visual costume that is easy to understand in seconds — and even better once the lights go out.
Full dinosaur look
The skull hood and skeletal back work together for a much bigger transformation than a basic pet shirt.
Lightweight costume
The two-piece design keeps the costume simpler and lighter than many bulky Halloween outfits.
Camera-ready
Made for Halloween photos, costume contests and the kind of lights-off reveal that works perfectly on Reels and TikTok.
FROM CUTE TO CRETACEOUS
Normal dog. Lights off. Dinosaur.
Use it for trick-or-treat walks, Halloween parties, photoshoots or just turning the hallway into Jurassic Park for a night.

Measure first. Roar later.
Use your pet's measurements instead of breed alone. If your pet falls between sizes, the larger size will usually give them more room.
How to measure: Measure back length from the base of the neck to the base of the tail, and chest around the widest part just behind the front legs.
| Size | Back | Chest |
|---|---|---|
| S | 25–30 cm | 35–45 cm |
| M | 30–40 cm | 45–55 cm |
| L | 40–50 cm | 55–65 cm |
| XL | 50–60 cm | 65–75 cm |
Double-check these measurements against your supplier before publishing. You can edit every value here in the theme editor.

GOOD TO KNOW
Questions before Halloween
Does it actually glow in the dark?
Yes. The glow material absorbs light and becomes visible in darker surroundings. Expose it to bright daylight or artificial light beforehand for the strongest effect.
Does it need batteries?
No. The glow effect does not require batteries or electronics.
How do I choose a size?
Measure your pet's back length and chest, then compare those measurements with the size chart. If they fall between sizes, choose the larger option for more room.
How does shipping work?
Shipping cost and estimated delivery are shown at checkout. Tracking is provided when available for your order.
