Great news!! The paperwork on my friend's retired greyhound shows that his grandfather and father had over 3000 puppies in their lifetime, each. Only a small percentage of greyhound pups make it to racing, and less of those make it past the first few races. How many puppies were put down to make a few good racers? Terrible sport. Now to get rid of the even more barbaric sport: horse racing. Of course, since rich people love horse racing more than dog racing, that one will be a battle.
