I don't know if this might have any use, but ever niticed 
that those little dogs, all they do it eat sleep and attack! 
While larger dogs (excluding the varieties bred to be 
aggressive) can often display an apparently wider range of 
emotions, like overprotectiveness of it's owners, and even 
affection. I could be biased against the little dogs, 
admittedly. I see no point in them.
