David and Barbara Yoder of Black Diamond Acres kennel in Seneca County, New York, decided to "depopulate" their kennel. David Yoder created a makeshift gas chamber out of a wooden whelping box (a wooden box usually used as a safe place for birthing dogs) retrofitted with a metal door and a three-horsepower engine. Filling the box with five or six dogs at a time, he pumped in carbon monoxide, walked away so he wouldn't get a headache, then came back a few minutes later to see if the dogs were dead. He repeated this cruel process over and over again, killing a total of 78 dogs and 15 puppies. 

Following the massacre, the USDA told the Yoders that euthanasia needs to be performed by a vet, and the kennel's license was cancelled. It's too little, too late. The Yoders need to be prosecuted for animal cruelty.

Tell the Seneca County District Attorney to prosecute the Yoders to full extent of the law.
