I would purchase tons of acres of land, and run a dog rescue and rat rescue organization. I would donate some of the money to the ASPCA and local humane society. I would buy a great dane, labrador, and a boxer (my 3 fav. breeds). I am sure there are lots of other things I would do, but I'm never gunna win the lottery, so why even worry about it. hehe.

P.S. There is no such thing as a pure white Clydesdale. White is only seen for markings, or if it is a paint color.
