Inuzaka Clan:
The Inuzuka clan is known for their use of dogs (some clan members prefer wolves) as fighting companions. Clan members are apparently given their own canine partner or partners when they reach a certain age. Thereafter, the shinobi and his/her dog(s) are practically inseparable. Clan members have distinctive red fang markings on their cheeks, animalistic eyes, and enlarged canine teeth. It would seem that due to the bond between a Inuzuka clan member and their canine partner(s), their chakra is allowed to mix and is shared between them, adding a feral appearence to the human partners, and makes a bond between then that affords them the use of the clan's Hiden collaboration-style techniques; such as the Dual Piercing Fang technique.
Inuzaka Clan attacks and traits:
Name: Dual Piercing Fang (牙通牙, Gatsūga; English TV "Man-Beast Ultimate Taijutsu: Fang Over Fang")
Type: C-rank, Offensive, Short range (0-5m)[1]
Users: Kiba Inuzuka with Akamaru, Tsume Inuzuka with Kuromaru
Debut (Anime): Naruto Episode 44
Debut (Manga): Chapter 76
The user and his partner spin at a ferocious speed and deliver many powerful beast-like attacks when contact is made with the target. The force of this attack is strong enough to drill through stone. This attack can be done alone, although it is less effective.
Name Man Beast Combination Transformation: Double-Headed Wolf (人獣混合変化・双頭狼, Jinjū Konbi Henge: Sōtōrō; English TV "Inuzuka Style: Man Beast Transformation Combo: Two-Headed Wolf")
Type: B-rank, Supplementary[1]
Users: Kiba Inuzuka and Akamaru
Using a modified form of a Combination Transformation, Kiba and Akamaru transform themselves into a large, two-headed wolf. In this form they can use Dual Wolf Fang.
Name: Dual Wolf Fang (牙狼牙, Garōga; English TV "Wolf Fang Over Fang"; English Games "Wolf Fang")
Type: B-rank, Offensive, Mid to long range (5m+)[1]
After Akamaru uses Dynamic Marking to mark a target, both he and Kiba use Man Beast Combination Transformation: Double-Headed Wolf to become a large, two-headed wolf. The two then perform a much more powerful Dual Piercing Fang attack. Like the lesser version, they spin rapidly to attack their target. Unlike the previous version, however, they move so rapidly that they can't see where they're going, hence the reason for the earlier Dynamic Marking, which allows them to track their opponents via the distinctive scent.
This attack is powerful enough to cut a person in two, and even dent a Rashomon gate. Even if the attack misses, its speed is so great that the surrounding air can slice like a blade. Such power is not without its drawbacks, however. Not only does this attack effectively blind both Kiba and Akamaru for its duration, but it tires them such that they can only perform it twice during Part I before requiring rest.
