World’s wealthiest dog sells Madonna’s old mansion for $29 million

Gunther VI, known as the world’s wealthiest dog — yes, there is such a thing — is a little richer after selling a nine-bedroom, eight-and-a-half-bath Miami estate once occupied by Madonna for a cool $29 million, according to People.

Gunther’s wealth comes from the late German Countess Karlotta Leibenstein, who died childless in 1992 and willed her entire $80 million fortune to her the pooch’s grandfather, Gunther III, according to ALux. The humans who manage Gunther’s estate have amassed a fortune worth about $500 million dollars, and have invested Gunther’s money in mansions and villas around the world.

The waterfront home was passed on to Gunther as part of his inheritance.

When a pet owner leaves an inheritance to a dog or any other animal, the money is usually put into a trust, with a human trustee named to make decisions on how it is spent. A caretaker is named for the pet, and that person receives regular funds to care for it.

Gunther’s caretakers also own other businesses on his behalf, and have put money into scientific research. They even founded Gunther Rescue to help animals in need.
