Dynamic Marking

While spinning through the air, a ninken starts urinating, scattering the urine across a wide area. Any opponents that the urine sprays are likely to be confused, embarrassed, and, if it gets in their eyes, temporarily blinded until they can flush it out. More useful to the ninken and their Inuzuka partner is that they can easily track the urine's scent, allowing them to locate anyone who has been marked by the urine regardless of where they are or where they go. This is an essential prerequisite for the Fang Wolf Fang, which makes users so fast that they can't see where they're going, necessitating that they locate targets by scent instead. Akamaru is quite skilled with this technique, becoming very accurate through practice with Kiba Inuzuka.

Trivia

 * In chapter 14 of Rock Lee's Springtime of Youth Full Power Ninja Chronicles, Akamaru performs a collaboration with Kakashi's ninken called Super Dynamic Marking.
