Here's an interesting theory:
Remember the girl in Kakashi's team? She had the Inuzuka red triangle marks on her face.
Wouldn't it be logic to assume that Kakashi learned to summon the doggies with the Inuzuka clan?
And yeah, Kuromaru is awesome, and talks!!!
Maybe Akamaru will grow to be like his daddy and learn how to talk, too.
