Dogmatix () is a fictional white terrier dog who is a companion to Obelix in the Asterix comics. Dogmatix is a pun on the words dog and dogmatic. In the original French, his name is Idéfix, itself a pun on the French expression idée fixe (fixed idea) meaning an obsession. On January 6, 2021, it was announced that the character would have his own animated television series titled Idefix and the Indomitables. Character synopsis Dogmatix is the only animal among the main characters of the series. His role is minor and funny in most of the stories, significant mainly as a 'bone' of contention between Asterix and Obelix as to whether he should be allowed to accompany them on their adventures. However, he is often seen doing something interesting in the background and occasionally fulfills an important part of the plot. In the words of the authors, Dogmatix is the only known "canine ecologist": he loves trees and howls in distress whenever one is damaged. Despite his small size, he is quite fearless. He has drunk the magic potion on a number of occasions, but his favourite treat is to 'chew a bone'. A dog similar to Dogmatix appeared in page 28 of Asterix & the Golden Sickle. Dogmatix first appears in Asterix and the Banquet. Sitting outside a butcher's shop in Lutetia, he observes Asterix and Obelix go in. He then follows them all around Gaul, appearing in nearly every panel of the remainder of the story. The two men do not notice him until the very end when he finally attracts Obelix's attention at the closing banquet and is given a pat on the head and a bone. He was meant to be a one-off character (hence his leaving the village in the final picture) but he was so effective it was decided to bring him back. Pilote, the magazine that published Asterix, held a contest to find a name for the dog. Hundreds of suggestions were received. The winning name, Idéfix, was submitted by Hervé Ambroise, Dominique and Anne Boucard, and Rémi Dujat. In the next adventure, Asterix and Cleopatra, Dogmatix is given his name and plays a more active role. Asterix and Obelix argue about whether or not Dogmatix should accompany them to Egypt, but he proves his worth by following the Gauls into a pyramid in which they were lost and guiding them out safely.
