Dogmatix (French: Idéfix) is a small but mighty character in the Asterix series. Fans instantly recognize him as the faithful companion of the indomitable Gaul, Obélix. Known for his unwavering loyalty and determination, Dogmatix has evolved alongside the Asterix universe, becoming a beloved figure in his own right.

Dogmatix received his French name after a contest held by Pilote magazine, where the prize was a signed album. The winning name was officially announced on December 12, 1963, in issue 216 of the publication.

Goscinny and Uderzo explained their decision as follows:

“It wasn’t really easy to make a choice. There were lots of suggestions, and some very funny ones; let’s mention: Patracourcix, Papeurderix, Trépetix, Paindépix, Toutousanprix, and other Minimix. Most of the letters were accompanied by drawings representing Asterix, Obelix, and the little dog, still anonymous. We chose Idéfix because it’s a short name, catchy, and sharp to the ear. It fits the character of the little dog well; indeed, he is a young animal with fixed ideas: he always wants to follow his two Gaulish friends and is always thinking about eating big bones.”

The name comes from the phrase avoir une idée fixe, which describes being obsessed with a particular thought, implying stubbornness or persistence. The -ix suffix aligns with the series’ Gaulish naming conventions.

As is typical for characters in the series, the name was adapted in translations. Some versions retained the original meaning or phonetic feel, such as Idéiafix in Portuguese, Ideafix in Spanish, İdefiks in Turkish, and Idefiks in Polish.

Others took a more creative approach, including Gafarelix in Occitan and Waldix in Alsatian. The English version, Dogmatix, cleverly combines the notion of dogmatic thinking with a nod to the fact that he’s a dog. I am not sure he is a very dogmatic thinker though.
