If I won millions and millions I'd:
*Pay off my debts along with all my family members debts.
*Give money to local animal shelters.
*Buy 25 acres or so and build my dream house with attached 8 kennel indoor/outdoor runs and acres and acres of fenced in land.
*Build a shelter on my property and open my own rescue.
*Buy trailers/campers to make into mobile spay & neuter units for local shelters to have.
*Put money away for my neices and nephew for college.
*Travel with my family, first would be an Alaskan cruise!!

If I won a smaller amount I'd pay off my debts and buy land to build a new house on.
