Does Maurizio Mian Have Any Pets?

Gunther VI (Dog)

Breed: German Shepherd | Adopted 2018

Gunther VI, born in 2018, is considered the world’s richest dog with a fortune estimated at around $400 million. He comes from a lineage of German Shepherds, starting with Gunther III. The story was that Gunther III inherited $80 million from his human, a German countess named Karlotta Liebenstein. Gunther VI’s owner and handler is Maurizio Mian, who is also CEO of The Gunther Corporation. Gunther VI made headlines in 2021 for selling his Miami mansion for $32 million, after his grandfather, Gunther IV, bought it from Madonna in 2000 for $7.5 million. In February 2023, Gunther VI bought Nicolas Cage’s island in the Bahamas. After the release of the 2023 Netflix docuseries Gunther’s Millions, it became widely known that the story of Karlotta Leivenstein was a hoax and Gunther VI’s wealth is actually Maurizio Mian’s.

Gunther V (Dog)

Breed: German Shpherd | Adopted 2005

Gunther V is part of the Gunther German Shepherd dynasty and was formerly the world’s richest dog, before his son, Gunther VI, took his place. Gunther V lived from 2005 until 2018.

Gunther IV (Dog)

Breed: German Shepherd | Adopted 1992

Gunther IV the German Shepherd was the original “World’s Richest Dog” and he lived until the age of 13 (1992 until 2005). His official caretaker was Maurizio Mian, who also ran The Gunther Corporation. His story was that his dad, Gunther III, was left an $80 million dollar trust when his human, German countess Karlotta Leibenstein, passed away in 1991. Gunther IV was well known in his home country of Italy during the 1990s. He became famous in the United States in 2000, after buying Madonna’s Miami mansion for $7.5 million, which his grandson, Gunther VI, sold in 2021 for $32 million. After the release of the 2023 Netflix docuseries Gunther’s Millions, it became widely known that the story of the countess was fake and that the money was Mian’s family’s. Gunther IV was a puppy related to Gunther III, who was actually the pet of Mian’s former girlfriend, Antonella Signorini.

Gunther III (Dog)

Breed: German Shepherd | Adopted 1980

Gunther III is a German Shepherd that started the “Gunther Dynasty” of the world’s richest dogs, with his great-great-grandson Gunther VI currently holding that title. He lived from 1980 until 1992. The story was Gunther III was the dog of a German Countess named Karlotta Leibenstein, but was previously Leivenstein’s son’s dog. Her son, also named Gunther, committed suicide at the age of 26. Leibenstein had no other children or family, so she left her $80 million fortune to the dog. After Gunter III passed away in 1992, his son, Gunther IV, took over his estate.

When the 2023 Netflix docuseries Gunther’s Millions was released, it was revealed that the story of the Countess was a hoax by Maurizio Mian, the official handler of Gunther III and his succession. Gunther III was actually Antonella Signorini’s dog, who was Mian’s girlfriend in the 1980s. Gunther III’s real story is he started to get very ill at four years old. Mian, who considered Gunther III his dog as well, tried out a new osteopetrosis drug that his family’s pharmaceutical company created. The drug worked, improving Gunther III’s health and letting him live to the age of 12. Mian used Gunther III to help promote the new drug. This ended up inspiring him to create the story of the Countess and Gunther IV.

Gunther III was actually named after Gunter Sachs, who was one of iconic French actress Bridget Bardot’s husbands. The “III” comes from Gunther being Signorini’s 3rd German Shepherd.
