四脚の術, Shikyaku no Jutsu: "All-fours Jutsu."
Kiba opens up his battles with this jutsu. Basically, as the name suggests, he gets on all four of his limbs, chakra flaring up from his body. This increases his agility -- nails growing a couple centimeters longer to help him run, and especially his senses. Even the faintest smell would be able to be detected by his nose, because this techniques boosts his senses up to a thousand times, as well as his speed. He'll be able to attack an opponent quicker than he or she could even think he's fast.
獣人分身, Jūjin Bunshin: "Man Beast Clone."
There are a series of steps that goes with this jutsu; first, Kiba feeds Akamaru and himself a soldier pill, which is a special medicine that allows the person who'd ate it to fight for three days and nights straight. Since Kiba and Akamaru specializes in beast-like attacks, it's perfect for their use. That said, the pill turns Akamaru red, and in that form, jumps on Kiba's back. When Kiba activates the jutsu, Akamaru turns transforms into a Kiba-clone, and would be able to perform every jutsu Kiba does.
通牙, Tsuuga: "Piercing Fang."
My personal favorite; Kiba allows himself enough speed to make a horizontal tornado that would pierce right into his opponent. His keen sense of smell helps detect where exactly his enemy is, because doing this, it's too quick to see where he/she is, so he relies on his senses during this attack.
牙通牙, Gatsuuga: "Fang over Fang."
Very similar to Tsuuga. This time, it's a combination of Juujin Bunshin (Man Beast Clone) and Tsuuga. Akamaru and Kiba would stand side-by-side, arms extended to the opposite side of eachother. They would they slap their palms together, jumping at the same time. This creates a tremendous amount of speed for them, and it helps eachother perform Tsuuga together. The combination of Kiba and Akamaru doing Tsuuga in this manner would create Gatsuuga.
人獣混合変化・双頭狼, Jinjuu Konbi Henge: Soutourou: "Man Beast Combination Transformation: Double-Headed Wolf."
Super long name for a super hard technique, no? Well, this move, like Juujin Bunshin, requires a series of moves. Unlike Juujin Bunshin, however, Akamaru doesn't need the soldier pill. Now, first, Akamaru hops a good ten feet above his opponent and does a move called Dynamic Marking; basically, he twirls horizonally and pisses at the same time, spraying his urine all over his opponent. Kiba and Akamaru then performs the jutsu and turns into a gigantic double-headed wolf (think Cerberus). This would allow them to perform Garouga that will be explained next.
牙狼牙, Garouga: "Double Wolf Fang."
Their "ultimate" move that uses up so much chakra that they can only do it twice. After transforming into a double-headed wolf, Kiba and Akamaru proceeds doing a "Tsuuga" in that form. However, this is about ten times stronger than your regular Tsuuga; the enormous amount of speed blurs their vision to the point where they can't even see anything. Like Tsuuga, they rely on their senses on this, which was why Akamaru had sprayed his urine upon the opponent for that purpose. When the enemy is hit at the dead center with this move, no matter how strong they are, they will be split into two.
