Akamaru is a loyal ninja dog in the Naruto series and the constant companion of Kiba Inuzuka. He is a member of the Inuzuka clan’s animal partners, trained to fight alongside his human teammate in battle and tracking missions. Though small and often carried by Kiba early in the series, Akamaru becomes stronger over time and participates in combat using coordinated attacks, enhanced senses, and teamwork. He serves as both a support fighter and a symbol of the close bond between the Inuzuka clan and their ninken.
