The NZVA does not support the use of electronic behaviour modifying collars (e-collars) that deliver aversive stimuli for the training of dogs.

E-collars have the potential to harm both the physical and mental health of dogs. They are an aversive training method that have in some studies been associated with significant negative animal welfare outcomes (1) .

Positive reinforcement training methods are an effective and humane alternative to e-collars for dog training (2) .



E-collars provide an aversive stimulus either by delivering an electric shock or vibration from a battery unit through electrode studs inside the collar.

E-collars can be activated in the following ways:

  • hand-held operator remote control,
  • noise (anti-bark collar),

The use of e-collars is controversial and their use is banned in ten countries including England, Denmark, Norway, Sweden, Austria, Switzerland, Slovenia, Germany, Finland, Wales. E-collars are also illegal in some states of Australia and some provinces of Canada.



Shock collar use in dogs with predatory aggression

While some may view shock collars as a simple method that can be effective for training specific dogs with predatory aggression, they inflict pain and risk negative welfare outcomes (see Appendix). The use of pain to train dogs is no more acceptable or humane when it is administered by remote control, than if it was delivered as a physical blow such as a punch or kick.

Training methods to manage recall in the presence of livestock and other dogs, based on positive reinforcement have been shown to be as effective(3) , or even superior(4) to shock collar methods. In addition positive reinforcement training methods do not pose any risk to the wellbeing of the dog.

As there exists an effective humane alternative training method for predatory aggression, the use of shock collars to manage this problem, even when euthanasia is a possible alternative, is not supported.

Anti-bark collars

Electronic anti-bark collars that deliver aversive stimuli such as a shock or citronella spray have been shown to have limited efficacy in controlling excessive barking. Veterinarians, dog owners and trainers should seek to identify when anxiety, loneliness, hunger or illness are contributing to excessive barking and address these issues in order to manage problem barking. Protocols to help owners understand causes of barking and educate them about ways to shape and reinforce quiet behaviour may provide better long-term solutions for this widespread behaviour problem(5) .



In order to protect dog welfare the NZVA recommends:

  • owners should not use e-collars on their dogs, but instead use positive reinforcement training methods, or seek assistance from a trainer skilled in these methods.
  • local and regional councils should not promote the use of shock or citronella collars to manage nuisance barking in dogs. Instead owners should be encouraged to address underlying reasons for problem barking. Councils may need to allow additional time for owners to use other methods to prevent nuisance barking.
  • kiwi aversion training schemes should consider moving to higher welfare positive reinforcement methods for training dogs.
