1. Gunther
Dog (£90 million or $145 million)
Now Gunther isn't just a bit rich, he's absurdly, offensively loaded. The German Shepherd inherited his fortune from his father, who in turn had received the money from his completely not crazy owner Karlotta Liebenstein when she died. Aside from spending his money on the obvious (chewy bones, bitches), Gunther also purchased Madonna's old Miami home and a rare white truffle worth £1,000, a favourite delicacy of pavement-sniffing, bin-foraging dogs.
