there Any character rivalling Kiba?

[KGB Kakuzu]

If we list only using scents....probably no one except Akamaru or his sister Hana

 

[grizzlyshree]

Kiba rocks!

 

[Blondephile]

what about Kankuro?

 

[SeriousDogg]

There isn't any character that fodder as Kiba...

 

[Flakez]

Yes he is the best at sniffing (can't believe i said that) and so what? He is worthless character, his relevance to the story is as much as fodder #51251289151.

 

[EZQ]

In tracking down opponents he is the best (if we talk about keen senses), no rival in that department

In battle his powerlevel can be matched with Shino's
