<p>He took advantage of the enemy's weakness, nothing wrong with it, even if it's a fart. Also, you bring up Kurama, yet Kiba used and still uses Akamaru, a dog, in every single fight. Yet nobody is picking on him. And rightfully so. Akamaru is part of Kiba's character, in the same way Kurama is part of Naruto's character.There is nothing wrong in Naruto using Kurama in battle. But in this particular battle, Kurama had nothing to do with. Naruto is an Uzumaki as well, and has healing, stamina and can withstand hard hits on his own. In part 1 they made it pretty obvious when Naruto was using Kurama's chakra, and in Kiba's fight was not the case.
