Choose Wisely When Considering Shock, Prong or Choke Collars

Dog Owner Responsibilities by William E Campbell I think many professional dog trainers will appreciate what William Campbell said about using "shock collars" in 1999.  I too have referred to these individuals as "predators" taking advantage of dog owners, who either lack understanding what their dog/s are communicating or as Campbell suggests prioritizes needs of the individual, not the pet.
