What is the income-happiness gradient for dogs?

Gunther the German shepherd spent a recent morning playing with his tennis ball, rolling in the grass, slobbering a little and napping a lot. Later, he had a “meeting” with the real estate agents selling his Miami mansion that his handlers bought from Madonna.

And of course Gunther was wearing his very best faux diamond dog collar for the meeting — his real gold collar is back at his main home in Tuscany. As crazy as it sounds even by Florida’s standards, Gunther VI inherited his vast fortune, including the eight-bedroom waterfront home once owned by the “Material Girl” singer, from his grandfather Gunther IV. At least that’s what the handlers who manage the estate say.

The Tuscan-style villa with views of Biscayne Bay went on sale Wednesday for $31.75 million — a whopping markup from the purchase two decades ago from the pop star for $7.5 million. The home also boasts a gilded framed portrait of Gunther IV over the living room fireplace.

The dog’s lineage dates back decades to when Gunther III inherited a multimillion-dollar trust from late owner German countess Karlotta Liebenstein when she died in 1992. Since then, a group of handlers have helped maintain a jet-setting lifestyle for a succession of dogs. There are trips to the Milan and the Bahamas, where the latest Gunther recently dined out at restaurants every evening — his handlers like to make sure he’s well socialized.

A chef cooks his breakfast each morning made of the finest meat, fresh vegetables and rice. Sometimes he enjoys caviar, but there’s never any kibble in sight. He travels by private jet, works on obedience skills daily with his trainer and sleeps in a lavish round, red velvet bed overlooking the bay.

“He lives in Madonna’s former master bedroom,” said real estate agent Ruthie Assouline who nabbed the listing with her husband Ethan for the 1.2-acre (0.5 hectare) property in a row of a half-dozen waterfront homes next to a public county park and on the same street where Sylvester Stallone once lived.

“He literally sleeps overlooking the most magnificent view in an Italian custom bed in the former bedroom of the greatest pop star in the world.”
