Are Shiba Inus good family dogs?

Yes, Shiba Inus are good family dogs. They are devoted, alert, independent yet loyal pets who are fastidious in cleaning themselves (and thus relatively easy to housetrain) and a joy to look at. 

They can be iffy with other dogs, so a household where they are the only dog is usually ideal, though, of course, with the proper socialization, they can befriend other dogs as well. They need a person who knows how to be in charge, or they will find themselves the boss of the family.
