Naruto's Growth…!! (ナルトの成長…!!, Naruto no Seichō…!!) is chapter 75 of the Naruto manga.
Kiba, remembering what a terrible student Naruto was, states that their fight will be an easy victory. He and Akamaru, a dog and thus a permitted tool of battle, immediately attack, surprising Naruto by their speed and ferocity. Determined to not be looked down upon, Naruto writes off Kiba's attacks as pathetic. Kiba throws a smoke bomb to block Naruto's vision while Akamaru attacks him. When the smoke clears Akamaru stands beside a defeated Naruto. Akamaru returns to Kiba but immediately bites him, being Naruto in disguise while a shadow clone restrains the real Akamaru. The observers are impressed by Naruto's tactics.
