Inuzuka Clan

The Inuzuka Clan or Inuzuka family is known for their use of ninken as fighting companions and are easily identified by the distinctive red fang markings on their cheeks.

The members are also given their own canine partner(s) when they reach a certain age. Thereafter, the shinobi and their dog(s) are practically inseparable. It would seem that due to the bond between an Inuzuka and their canine partner(s), their chakra is allowed to mix, and is shared between them, adding a feral appearance to the human partners, and makes a bond between them that affords them the use of the clan's collaboration jutsu, such as the Fang Passing Fang. The clan members are also able to communicating with canines even if unlike Kuromaru, the dogs cannot talk.
