I got my huahua for my birthday in November.  Oreo is a good boy and I love him.  He is only naughty when he goes potty in the house.  He is getting better but still does it.  His favorite toys are cat toys.  It is hard to find little toys for him.  We got little dog toys but he steals the cats toys.  Mom says he is like a cat he washes his face and feet all the time.  He likes to steal my socks too.
