Inuzuka Clan

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

Overview
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 communicate with canines even if unlike Kuromaru, the dogs cannot talk.

Trivia

The name "Inuzuka" also originates from the Nansō Satomi Hakkenden, a 19th-century series of novels about a group of samurai brothers who each embodied the eight fundamental principles of Buddhism.
 * The known Inuzuka members are all named after a part of the body of a dog (fang, nose and claw), while their dogs are named after colours (red, grey and black).

 * The facial markings of the Inuzuka clan members are similar to the facial markings on San's cheeks, from the Miyazaki film, Princess Mononoke.
