Her name is Conchita, a thin, spa-loving, diamond-draped heiress, and she's at the center of one of America's nastiest estate battles.
She is also a dog -- a chihuahua who was the favorite of the late Miami heiress Gail Posner, a daughter of the corporate takeover artist Victor Posner.
When Ms. Posner died in March at age 67, Conchita and two other dogs inherited the right to live in her seven-bedroom, $8.3 million Miami Beach mansion, their comfort ensured by a $3 million trust fund.
