The remaining 6 tracks will be allowed to remain open beyond this date if they can prove that they are able to maintain financial stability. There are just 17 dog tracks left in the United States today, 11 of which are in Florida, and they must close by December 31, 2020. Since 2001, more than 30 dog tracks have closed across the country, and dog racing currently accounts for fewer than 1% of all wagers placed in the United States each year.
