At least 152 dogs suffered injuries that were so severe they had to be euthanized. At least seven died as a result of illnesses contracted in the kennels.
More than 700 injuries were reported between January 2008 and September 2009 at Wheeling Island, West Virginia's other dog track,
Theil said his favorite Maloney ad featured Holly, Maloney's golden retriever that passed away several weeks ago.
Theil notes Maloney's touching words at Holly's death.
"By contrast," Theil writes. "Maloney's opponent is long-time politician Earl Ray Tomblin. Tomblin's mother and brother are both greyhound breeders and he has staunchly defended greyhound racing, an industry that is cruel and inhumane."
A spokesman for the Tomblin campaign declined to comment.
It's not clear if Theil's endorsement can speak for the full organization because it is a tax-exempt group that can have only limited involvement in politics.
Maloney's attacks on Tomblin have often centered on the state money his family has received. But the ad goes a little far in its accusations.
For instance, one ad said Tomblin had once voted "to direct" the money to his family business as a member of the Legislature. While Tomblin did vote for the bill that set up the fund, the money is distributed based on the performance of the dogs and is not something Tomblin directly controls.
