Akamaru is a nin-dog from Konohagakure's Inuzuka clan. He is Kiba Inuzuka's partner, as well as his best friend and constant companion. Akamaru has been described as active and devoted. This can be seen from his interactions with people especially his best friend and companion Kiba whom he has always been with since the two met. They often spend their time going on walks, or more accurately, running through trees chasing one another. His devotion is most often seen when Kiba is hurt in battle, Akamaru will immediately run to his side.
