Conchita
When she passed away in 2010, Miami socialite Gail Posner left a $3-million trust fund alongside a seven-bedroom mansion worth $8.7 million so that her beloved Chihuahua Conchita could live out her final days in comfort. The incredible inheritance is perhaps no surprise given the pooch’s pampered existence before her owner’s death—in fact, Posner was known to spend a fortune each month to gift her pet everything from Louis Vuitton bags to pearls, dresses and even makeup.
