Four Legs Technique

This technique grants animal-like accelerated fighting instinct and reflexes. By stretching chakra around one's entire body and moving on all fours, one obtains super-high speed, like that of a wild animal. Taught only to the members of the Inuzuka clan, this technique will add even more to their feral-like appearances; their canine teeth and their finger-and-toenails grow to claw-like length, their eyes become more wild. When under the effects of this jutsu, an Inuzuka will display feats of physical strength, speed, and endurance when they are in this state. The form is best suited for using and supporting the ferocious hit-and-run tactics that the Inuzuka clan are known well for.

Trivia

 * While Naruto Uzumaki is known to be prone to manuvering on all fours on occasion in his normal state, he'll also experiences a number of other changes similar to this technique when he goes through his initial transformation into his Jinchūriki Form.
