Stop grayhound racing in florida

Before today I didn't know how brutal and cruel this was. The dogs are abused, they are beaten put in tiny pens hardly big enough for them to get up. They are let out twice a day for 10 minutes each time. We saw the scars on several dogs where theyhad been beaten. If they don't race fast enough they are killed. These dogs are gentle.One dog I saw was scared to death of all men. Please stop this and sigh this petition. Please help stop the suffering of these dogs.
