Every year 8000-10000 lose their life when they are no longer profitable for the track.
It takes nearly 1000 greyhounds to operate the average greyhound track.
Greyhounds start racing at the age of 1 1/2 and are usually retired by 2 1/2.
Mistreatment of greyhounds varies from track to track and kennel to kennel.
Most greyhounds live in their cages 18-22 hours per day and sleep on thin carpet or newspaper - often wet from urine and water.
