Greyhound Racing: Running for their lives
Racing greyhounds is another cruel sport which exists merely for human amusement. During their whole racing career, greyhounds are kept in a tiny 3 feet x 3 feet crate for about 22 hours daily, except on the days they race. The dogs are also starved before the race begins; the hope is that the dogs will run for its food faster to satisfy their hunger. Tens of thousands of greyhounds are bred just for racing; unfortunately, many don't make the cut and are disposed off in unimaginable ways. When their racing career ends, several greyhounds meet the same fate as those that didn't make the cut; they are starved to death, bludgeoned, shot, electrocuted, or dropped off for research.

Dog fighting is a blood sport, where two dogs attack each other viciously until one kills or injures the other severely. People make money out of watching and betting on such cruel fights. In July 2007, the American football player Michael Vick was indicted on dog fighting charges.
