Inuton (犬遁, "Dog Style) is a rare Jutsu developed by Tatsuya during his time as an ANBU, with the assistance of several supervisers and other ANBU members. Inuton, while not actually a form of release or Kekkei Genkai is named so because of the fact that it in one jutsu can make use of Fire, Earth, and Wind elements - being a Hiden Jutsu only those currently in the ANBU are taught its usage; and to teach it to someone outside of ANBU, even if they had been ANBU themselves at an earlier point is concidered a crime unless the instructor has acclaimed specific clearance on the matter from one of his superiours, usually the current Hokage or the current Head of the unit.
