Myth: You need an electronic shock collar to either train your dog or to teach it to stop barking. (See Myths 1 & 2)
DO NOT USE: The use of shock collars on dogs is a very emotional topic and discussions will often degrade into personal attacks.
According to Polsky’s study (click here) dogs kept in shock containment systems (i.e. invisible fence or underground fence), showed extreme aggression towards humans, over and beyond their normal behavior. ON top of that it showed that shock collars only work a small percentage of the time anyway. Basically dog just learn to be afraid of people and the collar! Not to mention what it does to your dog’s health!
