Stopping Greyhound racing and killing

Greyhounds racing is inhuman because these dogs are kept in cages most of the time and they are muzzled most of the time too. They are starved, kept away, and tortured.
• A greyhound was electricuted in the middle of a race track.
• A man was "retiring" unwanted greyhounds by killing them. He killed over 3,000 greyhounds.
This is so wrong and needs to be stopped immediately. These dogs don't deserve a life locked up in small cages, wearing a muzzle 24/7, and being tortured. They deserve someone who will take care of them and treat them right!
