A modified version/mix of the Transformation Technique and clone technique, which is unique to the Inuzuka clan, allows a canine-user to transform their animal companion into a perfect copy of themselves. When combined with the Four Legs Technique, the user and the animal become virtually impossible to tell apart, since both act equally feral. Like any transformation, the technique can be broken by identifying and attacking the animal, thus dispelling the transformation. This technique is often followed by the Fang Passing Fang.
This technique's complete name is Imitation Beast Ninja Art: Beast Human Clone (擬獣忍法・獣人分身, Gijū Ninpō: Jūjin Bunshin) when used by Kiba and Imitation Human Ninja Art: Beast Human Clone (擬人忍法・獣人分身, Gijin Ninpō: Jūjin Bunshin) when used by Akamaru.
