I had a pomeranian once and his name was Chewbacca and he was very tempermental and snapped at everyone!
It would "claim its territory" at my parents house...it'd go outside of the yard and chase kids on bikes down the road, the mailman, neighbors it was aweful! All he was trying to do was protect our family...but took he to the extreme where it embarassed our family. We wound up giving it to a nice elderly couple who love him to peices. I wouldn't reccommend getting a pomeranian if you have kids...they are adorable and have their cute moments though!
