Akamaru

Akamaru is the nindog of Inuzuka Kiba. He is his best friend and plays an important part in all of Kibas attacks. As a puppy he is either in Kibas jacket or on his head but he later grows to be so large that Kiba can ride him. He has very good senses even for a dog and can communicate with Kiba. Akamarus name means red with maru at the end which is simply an ending for a boys name. Other males in the show share the suffix. When he eats a soldier pill his fur turns a dark red color.
