Before we get started, I want to point out there is a dog wearing this Toothless costume.
Don’t believe me? Check this out.
Say hello to Loki, quite possibly the world’s happiest dressed dog. Loki is the model of a dog’s Toothless costume from “How to Train Your Dragon.” The directions walk through the entire process, and even includes how to make a dummy body of your dog, if you happen to have a dog chill enough to sit still for duct tape and plastic. My dog, not so much, but for those of us with less than patient dogs, there’s also directions on how to take measurements instead.
Rogue Siren is the creator of the costume and she’s also got an Instructable on how to create your own mermaid tail (she performs as a mermaid for parties in the Atlanta area).
