I breed Japanese Spitz and I also own quite a few German Spitz, yes they can be a bit yappy, but they are not nasty in any way, and if they are then blame the owners, they are a joy to have and train, my daughter has just competed at Agility in Crufts this year with her Japanese Spitz who is 5 years old and also competed last year with her, their coats do need a regular brush but they keep themselves clean most of the time.
It is very rare that a Japanese Spitz ever comes up for adoption so if you are interested in owning one of this breed, read up on it and go ahead and adopt, you won't be dissapointed.
