"Inu" (犬 Inu) is an archetype in the Yu-Gi-Oh! ZEXAL anime. Members have existed in the TCG/OCG since Power of the Guardian, but received no support until ZEXAL. Though almost all members of this archetype have "Dog" in their TCG names, the anime-only support cards for this and the "Dog" archetype list them as separate from one another.
"Inu" with the Japanese furigana of ドッグ (Doggu) or けん/ケン (Ken), all have the same meaning of the word dog.
