Is there something about successful businesswomen and their pet dogs?
The late Muriel "Mickie" Siebert, first woman with a seat on the NYSE, left $100,000 for the care of her beloved Chihuahua, Monster Girl.

Siebert died in August at age 84. Most of her nearly $50 million estate she left to the Muriel F. Siebert Foundation, which promotes finance education. She also left $1.5 million in a trust for her sister; money and jewelry to friends; and airline miles to the executors of her estate.
Of course Siebert's bequest is nothing compared with the $12 million that hotel magnate Leona Helmsley left to her dog Trouble in 2007.
