10 Reasons Not to Use Shock Collars for Dogs

In the realm of dog training, shock collars, also known as electronic collars or e-collars, have been a subject of considerable debate. While some argue for their efficacy in obedience training, an increasing body of evidence suggests that their disadvantages far outweigh any perceived benefits. This article delves into ten compelling reasons not to use shock collars on dogs supported by scientific studies and modern dog training principles.

1. High Risk of Misuse

Shock collars or E-collars require precise timing and understanding, which many dog owners lack. Incorrect use, often stemming from inadequate training on how to utilize these devices properly, can lead to increased fear and anxiety in dogs. Studies have shown that incorrect timing in aversive training can exacerbate behavioral problems rather than solving them (Source: Journal of Veterinary Behavior, 2018).

2. Shock Collars are Aversive

The very nature of shock collars is to deliver an unpleasant stimulus. They are incapable of positively reinforcing good behavior, which is a cornerstone of effective dog training. Positive reinforcement training, where desirable behavior is rewarded, is supported by numerous studies as a more humane and effective training method (Source: Applied Animal Behaviour Science, 2017).

3. Unfair Expectations on Dogs

Many dog owners choose a pet based on their lifestyle, without considering whether the dog’s breed and temperament align with their expectations. Utilizing these “training collars” to force a dog to adapt, especially when the choice of breed was not ideal, is unfair. This approach overlooks the importance of matching a dog’s natural tendencies with the owner’s lifestyle. Most behavior issues are in fact misunderstandings. Often the dog’s needs are not being met one or another ways.  Simply changing a few things around in your dog’s daily routine and adding positive reinforcement training for good behaviors can make a world of difference in their behavior.

4. Encourages Positive Punishment

Relying on e-collars can lead to an over-reliance on positive punishment (adding an aversive stimulus to decrease a behavior) and diminish the use of positive reinforcement (rewarding good behavior). This can create an unhealthy dynamic where the dog learns to behave out of fear rather than understanding and trust (Source: Journal of Experimental Psychology: Animal Learning and Cognition, 2019).

5. Potential for Physical Harm

If used incorrectly, e-collars can cause physical injury. This includes burns or sores from the electrodes, especially when used excessively or on high settings (Source: Veterinary Record, 2020). While this is fortunately not common, it is very possible with neglect or misuse.

6. False Sense of Security

Many dog owners use e-collars as a contingency for emergencies, such as preventing dog fights or stopping a dog from running away. However, relying on an e-collar for these situations can give a false sense of security and ignores the root cause: a lack of proper training and management (Source: Animal Cognition, 2018).

7. Shock Collars can Increase Aggression

E-collars have been linked to increased stress, aggression, and anxiety in dogs. The use of aversive tools can suppress a dog’s willingness to try new behaviors, leading to a phenomenon known as “learned helplessness,” where the dog becomes passive and depressed (Source: Pubmed, 2014; 9(9): e102722)

8. Negative Associations

The canine brain is adept at making associations with its environment. E-collars can cause dogs to associate everyday experiences, such as meeting new people or hearing certain sounds, with fear and discomfort. This can lead to long-term behavioral issues (Source: Animal Learning & Behavior, 2020).

9. Unpredictable and Misguided Use

The argument that e-collars are safe because they can be tested on humans is flawed. Dogs have different sensitivity levels, and the unpredictable nature of the shock, including varying intensities and accidental shocks, can cause undue distress and confusion (Source: Journal of Veterinary Behavior, 2021).

10. Detrimental During Critical Development Stages

Using e-collars during a dog’s adolescence, a crucial period for brain development, can have lasting negative effects. This is a time when dogs are learning about their environment and forming behavioral patterns. Aversive methods can instill fear and mistrust during this sensitive stage (Source: Veterinary Medicine and Science, 2020).


The use of e-collars in dog training is not only outdated but potentially harmful. The emphasis on positive reinforcement, understanding canine behavior, and building a relationship based on trust and mutual respect is key to effective and humane dog training.  Any behavior can be trained without shock collars and dogs with emotional issues including fear, anxiety and over arousal are not recommended to use these devices as it can make the problem much worse. As research continues to evolve, it becomes increasingly clear that methods promoting cooperation and understanding are far superior to those based on fear and punishment.
