Millionaire pooch selling Miami villa once owned by Madonna

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.
