Dr. Robert K. Anderson and his Gentle Leader dog harness. In 1956, the University of Minnesota's College of Veterinary Medicine and School of Public Health developed a joint program in veterinary public health, and Anderson became the first director. For more than three decades he taught both veterinary students and public health students about food safety, zoonotic diseases, and epidemiology. Dr. Anderson developed the Gentle Leader collar with Ruth Foster, then President of the National Association of Dog Obedience Instructors. The collar became widely popular when released in 1989. "Dogs are the only animals we train by choking" Anderson said.
