Dynamic Marking

This jutsu involves Akamaru urinating on a target, allowing both him and Kiba Inuzuka to track it by scent. The two practice this in the forest, and Akamaru is accurate enough to hit multiple targets in rapid succession. This is a prerequisite for using Double Wolf Fang, since the speed of the technique makes it impossible for the user to see while using it. Akamaru's urine is apparently caustic, given Sakon's comment that it burned when Akamaru urinated in his eyes.
