Are You Bow Lingual?

The Japanese knack for inventing useless and/or unwanted innovations has created a new toy. The Bow Lingual is "a 'dog emotion translator' which can reveal what canines are thinking."
Having owned a few dogs in my time I never found that I needed an emotion translator to live with them.
I consider myself to be a rather average pet owner and it seems to me that the way to read their emotions is to just let them run the house and they will be happy.
