The article briefly mentions non-lethal methods and that they are underfunded. I worked with a grad student who was doing research (supported by the USDA IIRC)

The article briefly mentions non-lethal methods and that they are underfunded. I worked with a grad student who was doing research (supported by the USDA IIRC) on different dog breeds for use as guard dogs. Ironically, sometimes the guard dogs will kill a calf — they assume due to boredom and playing too rough.
