Greyhound Stats
Just do any Google search. And, for instance:
The thousands of greyhounds that are surplus to the racing industry are more likely to end their days, not in front of a warm fire, but drowned, poisoned, beaten to death, starved, dumped on the streets or impounded and destroyed.
Greyhound puppies are killed if they fail to reach racing standards. Around two thirds are deemed fit, whilst the others will be put to death before they reach a year old.
Substantial numbers of greyhounds are exported to Spain for racing, hunting and coursing. Conditions in some Spanish kennels are appalling and many greyhounds are locked up 23 hours a day. Hunters and coursers often dispose of unwanted dogs by hanging and other horrifically cruel methods.
The natural lifespan of a greyhound is about 14 years, but the lives of most of those in racing end at 2 years old. Most greyhound owners and trainers, who are in the business to make a profit, are not prepared to pay the costs of allowing greyhound to live out their natural lives. Many are not even willing to pay the price of having the dogs humanely put to sleep by a vet.
There is just no way that good homes could ever be found for so many thousands of greyhounds every year. Greyhound racing inevitably leads to massive killing and suffering. The only real solution is abolition.
