"It's only through flukes that people actually learn what has happened to these poor dogs," Dorchak said. She says the state's department of racing stopped releasing greyhound injury reports to the public in November 2009. When they were still reporting, she says, "nearly 1,000 greyhound injuries occurred between 2007 and 2009. There were 67 dogs that died."
Additionally, Dorchak explained, reports provided details about the types of injuries dogs sustained, where they happened, and what were the outcomes. More often than not, the most common injury -- a broken leg -- led directly to euthanasia. Dorchak believes that's still the case in Arizona, but there aren't publicly available figures to calculate how many dogs suffer bone breaks. "We know more greyhounds are dying at Tucson Greyhound Park," she said. "We just don't know how many."
The same goes for several of the other states where dog racing is still legal. According to Ann Church, vice president of state affairs at the ASPCA, the laws and regulations for dog racing are different in each of the states where it's still allowed -- Arizona, Florida, Iowa, Texas, Arkansas, Alabama and West Virginia -- and few of them mandate transparency. Florida -- the state where greyhound racing originated and where there is still the greatest number of tracks in the country -- is one exception. In the spring of 2013, a law went into effect that requires tracks to report deaths, and the results have been harrowing.
