Do problems exist with greyhound racing? Yes. Greyhound racing constitutes animal abuse because of the industry's excessive surplus breeding practices, the often cruel methods by which unwanted dogs are destroyed, the daily conditions in which many dogs are forced to live, and the killing and maiming of bait animals, such as rabbits, during training exercises. The industry exists solely for the entertainment and profit of people—often at the expense of the animals' welfare. from : http://www.humanesociety.org/issues/greyhound_racing/facts/greyhound_racing_facts.html#Do_problems_exist_with_greyhound_racing
