A woman is suing to overturn the will of her companion, who died and left his Beverly Hills home to Samantha, his 13-year-old cocker spaniel.

Marie Dana, 32, lived with wealthy bathroom fixture manufacturer Sidney Altman, who died in 1996 at age 61.In his four-page handwritten will dated 1994, Altman left his home and $350,000 to Samantha, identified as his "loving companion," said Cary Goldstein, Dana's attorney.

The will asked Dana, his "good friend," to be Samantha's guardian for $60,000 a year. Altman also gave Dana an additional $50,000 to redecorate her house and go on a "massive shopping spree at Polo."

But once Samantha dies, the arrangement with Dana is canceled, with the house and estate going to charity.
