DIY Dinosaur Costume: Easy Spikes, Tail & Headpiece
How to make a DIY dinosaur?
A DIY dinosaur can be as simple or as detailed as you want, but the easiest approach is to start with a comfortable base and add recognizable “dino” features: spikes, a tail, and a hood or headpiece. For a pet-friendly version (like a dinosaur dog costume), comfort and safe materials matter just as much as the look.
Pick your base and plan the silhouette
Start with something that already fits well: an old hoodie, a dog sweater, a child-sized sweatshirt, or a plain green T-shirt (depending on who will wear it). Choose a dinosaur style—stegosaurus (back plates), triceratops (frill/horns), or T-rex (spikes plus tail)—then sketch where the spikes and tail will sit so they won’t interfere with movement.
Make the spikes (or plates)
Cut a row of triangles or rounded plates from felt or fleece. For a soft, plush effect, cut two of each shape, sew or glue the edges, and lightly stuff them. Attach them down the center of the back with a strong stitch or fabric glue, keeping the tips soft and avoiding anything rigid that could poke.
Add a tail that won’t drag
Create a simple cone or tube tail from fleece, lightly stuff it, and attach it at the back. Keep it shorter than you think—dragging tails get stepped on and can pull at seams. For pets, position the tail so it sits above the legs and doesn’t swing into their gait.
Create the “dino head” look
For humans, a hood with felt teeth along the edge instantly reads dinosaur. For pets, a lightweight hood or detachable headpiece can work, but only if it doesn’t block vision or ears. If your dinosaur is for a dog, the comfort-and-fit details in this guide are especially helpful: https://hovira.com/guide-adorable-dinosaur-dog-costume-fit-comfort-diy-tips/.
Finish with safe details
Skip hard plastic eyes and small loose parts that can become choking hazards. Use stitched felt accents, fabric paint, or embroidery instead. Do a quick “wear test” to ensure full range of motion and no rubbing at the neck, armpits, or belly.
