I had 2 Japanese Shiba Inus (ex now has them ). I used to own German Shepherds and miniature poodles. Someone in here indicated that you need to see them and experience them but you don't really get to experience them until you have one. Seeing one will never prepare you for having them.
They are hard work and they have their own personality. But that's what I love about them. My older Shiba Inu wouldn't even sit down unless there's a reason to. They do scream but only when washing them (prepare for the ear plug). They don't bark unless something is definitely wrong. My younger Shiba Inu talks to me when I talk to him. Not a bark but still a bit funny. Whilst the older one will just look at me like I'm a bit cuckoo (sort of telling me why am I talking to him when I know well enough that he's not going to answer back lol) My 2 Shiba Inus are totally different from each other so you'll never know what you'll get I guess.
I think if you're not sure, get a Shiba Inu. I wanted an Akita too but I loved my Shibas. It grows on you. I think the Shibas provided me a training ground for Akitas in a small package ie you can control them with a lead as they are not too big whereas I think an Akita will have me hanging onto its back lol
I was told that Akita Inus are the same and I would love to own a Japanese one which is so hard to find. I like the Japanese standard too as they look so much like my Shiba Inus. Where is the breeder in Perth? I would love to see it and probably buy one in the near future.
