Why can't Inuzuka clan's dogs use human language?


Why can't Inuzuka clan's dogs use human language when Kakashi's dogs can?
Also, how does Kiba and Akamaru understand each other?




Well the difference is quite simple.

the Inuzuka clan's dogs are simple dogs. They can understand human language
very well and are the "sidekicks" of the Inuzuka. Kiba and Akamaru understand
each other by ["Hand
Wave"](http://tvtropes.org/pmwiki/pmwiki.php/Main/HandWave). This is not
explained any further as it is prescriptive.

Kakashi's dogs on the other hand are Summoned. They are not "real" dogs but
spirits, comparable to Gamabunta, Gamakichi and the other [Kuchiose No
Jutsu](http://naruto.wikia.com/wiki/Summoning_Technique) summoned animals.
