It's amazing that this sort of thing wasn't shut down years ago. Foxes and coyotes are put in a pen with no exit and (up to) three hundred dogs basically tear them apart...
"On Wednesday, The Humane Society of the United States welcomed a decision by the Florida Fish and Wildlife Conservation Commission to crack down on inhumane fox and coyote pens in the state.
The Commission voted to continue its prohibition on fox and coyote pens at least until its June meeting, when it will consider a draft rule package to govern the facilities.
In pens, foxes and coyotes are captured from the wild, often shipped long distances and then released inside enclosures to literally run for their lives. Dogs are judged on their pursuit of the captive wildlife. The dogs often injure or kill the wild animals, leading to a constant demand to restock with more wildlife.
"We thank Fish and Wildlife Conservation Commission Chairman Rodney Barreto and the commissioners for their leadership on fox and coyote penning," said Jennifer Hobgood, Florida state director for The HSUS. "Controlling these facilities has long proved next to impossible — escape isn't the point of the game. We urge the commission to enact a complete ban when it revisits the issue in June."
