Why can't Akamaru talk like Pakkun?


How come Pakkun can talk to Kakashi when summoned (in fact almost all summoned
toads can talk), but Akamaru, who was brought up by Kiba since he was a pup,
cannot speak?




Although both Pakkun and Akamaru are considered
[ninken](https://naruto.fandom.com/wiki/Ninken) (dogs with heightened senses
and abilities, and as such, working alongside shinobis), the only difference
between them is Pakkun is actually a Summon (much like sage toads). Summons
are basically supernatural animal spirits and they take on anthropomorphic
qualities like talking, using weapons, wearing clothes etc. Akamaru is
basically a highly trained dog that can use ninjutsu.

Atleast, [Akamaru tried talking.](https://www.youtube.com/watch?v=5xDUwYbVYwQ)
