Checkers is a mixed breed dog that we got with Midnight.  The children spotted these two dogs as strays in the neighborhood and we have raised them from puppyhood for several years.  Checkers is a very nice, calm dog who actually seems to like everybody in the family, unlike Midnight who does not like adult men, especially (like me!). I believe that bog dogs were probably abused when younger, and they carry their fear of adults with them.
