A bark collar is a device designed to deter a dog from barking by providing a negative stimulation. The stimulation is delivered while the dog is barking so that they can associate the consequence with the act of barking (operant conditioning). When the correction delivered by the collar is stronger than your dog's desire to bark, the nuisance barking will stop very quickly.
In nature, negative reactions to an animal's behaviour plays a key role in the survival of all animal species, in that an animal learns that certain behaviours have consequences and need to be avoided. Accordingly, your dog will quickly learn that no barking means no correction.
These bark collars deliver a very low static pulse, similar to a tens machine at your physiotherapist. The correction is physically harmless to the dog. Most electric bark collars are activated by the vibration of the dogs vocal chords when they bark meaning that other dogs barking cannot activate your dog's collar. They are the most effective type of bark collar.
These collars send a burst of citronella in the direction of your dog's snout when they bark. The citronella spray is harmless to your dog. Most pet breeds of dogs respond well to a spray bark collar however, they are less effective with working breeds as there is generally no ability to increase the correction levels. They can also be expensive to maintain.
This type of collar delivers a high pitched tone (inaudible to humans) that is unpleasant to the dog. Some dogs are not susceptible to this tone. Also in multi-dog situations, all dogs will receive the correction whether they are barking or not. For this reason, they are best suited to single dog scenarios. There are also stationary devices that deliver the same type of ultrasonic tone.
This type of collar delivers a vibrating sensation to the dog's neck when they bark. They can be useful for very timid dogs or young pups.
