Akino is one of the ninja-dogs summoned by Kakashi Hatake.
Not much is known of Akino's origin other than he works with the rest of Kakashi's Ninken when they are summoned, and he is capable of fighting. He, like the others, is essentially a dog with human capabilities.
Akino like the other Ninken, resembles a dog. His fur color is a dusty light brown, very much like the color beige. He also wears sunglasses of a very dark shade, and they have very small lenses to accommodate his smaller eyes.
