Shock collars, also known as electronic collars or e-collars, are commonly used in dog training today. Some shock collars are remote operated, while others (such as with underground fences) automatically generate shock when the dog reaches a certain distance away from the underground line. Shock should never be used to train a dog regardless of the way that it is delivered.
The scientific research overwhelmingly demonstrates that shock leads to or contributes to fear, pain, aggression, panic and stress when compared to positive reinforcement training.
In fact, shock collars are considered inhumane and are illegal to use in many countries and regions including Scotland, Denmark, Norway, Sweden, Austria, Switzerland, Slovenia, Germany, Quebec, Wales and parts of Australia.
Many organizations have published position statements advising against the use of electronic collars including European Society of Veterinary Clinical Ethology (ESVCE), American Veterinary Society of Animal Behavior (AVSAB, Association of Pet Dog Trainers (APDT), Pet Professionals Guild (PPG), Humane Society of the United States, and the United Kingdom Kennel Club to name a few.
