@tanza Most people are not aware that the Shiba Inu is a smaller version of the Akita Inu. I had an Akita Inu and he was a great dog. Very protective of me and the other Pets. These Japanese Dogs are known for their Loyalty and their mission is to protect their families. They were bred for that. They were never used for Hunting rather they were raised to be protection Animals.
Shiba Inus do not come cheap. Although they are lesser known there are Breeders of this dog but a decent Breeder will explain their quirks. Akita Inus hate rain and mine always looked at me as if to say 'Please make this stop'! Shiba Inus have similar traits as the Basenjis. They don't trust new people easily and although the Shiba Inus can Bark they rarely do. Just enjoy your Charlie.
