Akamaru

Akamaru is Kiba Inuzuka's dog, best friend, and companion.

Abilities
Akamaru can sense an enemy's chakra, which tells him how strong the enemy is. As such, he was greatly afraid of Gaara. Akamaru is white colored until he eats a soldier pill, after which his fur becomes red.

Trivia

 * Aka means red, but can also mean baby. Maru is a suffix for Japanese boy names. So Akamaru can mean "baby boy" or "red boy."
 * His favorite food is the special dog food Kiba makes.
