DES MOINES, Iowa (AP) — A national greyhound protection organization says greyhounds sustained 175 injuries while racing at Iowa’s two racetracks between January 2011 and July 2012, and 24 of the dogs had to be euthanized. The Des Moines Register reports that broken legs were the most common reported injury over the 19-month period at the tracks in Council Bluffs and Dubuque. Other common injuries were sprains, tears and other broken bones. The group says several dogs suffered more severe injuries, including a fractured skull and a broken neck.

The report was compiled from records gathered by Grey2K USA, based in Somerville, Mass. The research found that the Council Bluffs track, which has races year-round, had 106 dog injuries, while the Dubuque track, which offers races between April and October, had 69 injuries.
