- - Kiba Inuzuka to Akamaru

Akamaru a shinobi dog from Konohagakure's Inuzuka Clan. He is the best friend and partner of Kiba Inuzuka, and thus the two are bonded together in each and every assignment under Team Kurenai.

Early life
While Kiba Inuzuka spent his last year in the Konoha Bending Academy, his mother, Tsume Inuzuka, entrusted her son with Akamaru, and as the customs of the Inuzuka Clan dictated, both would be bonded to life. While Akamaru attempted to urinate on Kiba's face right away, much to his mother and sister's amusement, the two became inseparable best friends.
