Bark collars are training devices that are placed on a dog’s neck and intended to lessen or deter barking in various ways by delivering a stimulus when the dog barks. These collars are meant to interrupt or discourage barking (usually automatically, without the need for moment to moment human assistance).
How Bark Collars Work
Most bark collars detect barking in different ways based on sound (i.e. another way to think of this is through a microphone that detects barking), vibration (vibrates vocal cords), or sometimes both (to avoid false triggers like barking from another dog). Once the bark collar senses barking, it then provides a correction, which will be variable based on the collar type.
Main Types of Bark Collars
Type How It Works Pros/Cons
Static/Shock Collars Delivers mild electric shock Often effective at stopping barking.
Controversial, can cause fear or aggression.
Vibration Collars Vibrates to startle the dog Gentler than shock, no pain
Not always strong enough to stop barking.
Ultrasonic Collars Emits high-pitched sound Inaudible to humans
May not work on all dogs; can annoy other pets
Spray Collars Sprays citronella or water Often effective, less harsh
Needs refilling; some dogs ignore it
Dual-Sensor Smart Collars Combine vibration + sound Reduces false activations
Often expensive
Do bark collars work
Bark collars can work, but their effectiveness and appropriateness depend on the dog, the type of collar, and the underlying cause of the barking.
They may work for:
- Excessive barking due to excitement or attention-seeking.
- When used correctly and humanely alongside training.
- For dogs that don’t respond to other forms of correction.
- In situations where barking must be controlled quickly (e.g. apartment living).
When Bark Collars Don’t Work Well:
- If the dog is barking due to anxiety, fear, or medical issues.
- Without addressing the root cause of the barking.
- When used as a shortcut instead of training.
- On sensitive or fearful dogs (can worsen behaviour).
Risks of using bark collars
Using bark collars comes with several risks, especially if used incorrectly or without understanding the root cause of your dog’s barking. The risks can be physical and emotional, amongst many other. Here is a list of the common risks to consider.
Physical Risks
- Skin irritation or burns from prolonged wear (especially with shock collars).
- Neck injuries if the collar is too tight or too heavy.
- Malfunctioning collars may deliver constant or unintended corrections.
Emotional & Psychological Risks
- Increased anxiety or fear, especially in sensitive dogs.
- Development of learned helplessness (where the dog gives up trying to communicate at all).
- Loss of trust in their owner or environment due to unpredictable or painful corrections.
Behavioural Risks
- Suppression, not resolution: the collar may stop the barking, but the underlying cause (e.g., fear, boredom) remains — or worsens.
- Increased aggression, especially with shock collars, some dogs may redirect frustration by becoming aggressive.
- Confusion or mis-association: dogs may not connect the correction to barking and instead associate it with nearby people, other dogs, or random stimuli.
Overuse or Misuse
-
Using the collar too much or not giving breaks can lead to chronic stress.
-
Using it as a solution rather as one part of a plan rarely results in long term success.
-
Collars that trigger, even when the dog is not barking (false positives), punishing the dog when this happens.
-
Bark collars can be especially risky for anxious or fearful dogs, puppies and elderly dogs and those with reactive and aggressive tendencies.
What do experts think about bark collars
Most experts, especially veterinarians, certified dog trainers, and animal behaviourists are cautious or critical of bark collars, particularly the shock-based ones.
Experts generally agree on addressing the root cause and emphasize that barking is a symptom, not the problem itself.
The common causes can be boredom or lack of stimulation, anxiety (especially separation anxiety), fear or reactivity or territorial behaviour.
Bark collars don’t address these causes — they only suppress the behaviour.
Organizations like the American Veterinary Society of Animal Behaviour (AVSAB) and RSPCA advise against the use of shock collars as they can cause stress, fear, or aggression, the likelihood of escalation in anxiety-related behaviour, and potentially damage the human-animal bond.
Some countries (e.g., parts of the UK, Germany, and Australia) have even banned shock collars for these reasons.
What are the alternatives
Experts and behaviourist support and recommend alternative training methods, such as positive training
- Rewarding quiet behaviour
- Redirecting to more appropriate outlets (e.g., chew toys, exercise)
- Teaching commands like “quiet” using treats and praise
- Positive reinforcement training
- Desensitization to barking triggers
- Puzzle toys and mental stimulation for boredom
- Professional help from a certified behaviourist
Conclusion
Bark collars are devices designed to manage excessive or inappropriate barking in dogs. However, they come with significant risks and are generally not recommended by experts. Instead, positive reinforcement training and seeking professional guidance are considered better alternatives. If you decide to use a bark collar, be sure to read the instructions carefully to minimize potential risks. Additionally, consider gentler options, such as vibration, noise, or spray collars, which may be less harmful for your pet.
