Bark Collars have an advantage over “manual” corrections (throwing a can, leash corrections, etc.) in that they’re more consistent. Which is key to any kind of dog training. The bark collars for dogs available in the market today can be categorized into three types.
Ultrasonic Buzzer Collar
The Ultrasonic buzzer collar is designed to emit a high-pitched ultrasonic whistle audible only to dogs, meaning humans would not be able to hear it. Dogs have a very sharp hearing. This noise will annoy dogs which will help the dog to associate its barking habit with the unpleasant noise from the collar and will eventually stop barking.
The ultrasonic collars has the advantage of being a mild intervention, and as such is suitable for timid and infrequent barkers. The disadvantage of ultrasonic collars is that most dog gradually become accustomed to the ultrasonic tone, meaning that correction becomes less effective over time. The collars also do not discriminate and have the effect of correcting all dogs nearby, making them less suitable for homes with multiple dogs. The disadvantage of ultrasonic bark collars is that some dogs can eventually tune the sound out.
Electronic Shock Collar
This bark collar is electronically programmed which allows the collar to deliver a mild, harmless shock every time the dog barks. Most bark collars have 6 shock levels. A mild shock is triggered during the first bark. The shock gradually intensifies after 30 seconds, that is, if the dog barks again. Each time the dog barks, the shock collar delivers a slightly stronger shock. The intensity of the shock grows during the 30-second intervals of the consecutive barks until it reaches up to the sixth shock level.
The term shock collar is a term used in order to describe a family of training collars (also called e-collars, Ecollars, remote training collars, Zap collars, or electronic collars) that deliver electrical shocks of varying intensity and duration to the neck of a dog (they can also be applied to other places on the dog’s body) via a radio controlled electronic device incorporated into a dog collar. Some collar models also include a tone or vibrational setting, as an alternative to or in conjunction with the shock. Others include integration with Internet mapping capabilities and GPS to locate the dog or alert an owner of its whereabouts.
Citronella Spray Collar
The citronella collars were first marketed in the United States in 1995, although they have been available for years in most European countries, where shock collars are illegal for use on pets. The Citronella Spray collar sprays Citronella or other pungent oil nearer to the nose of the dog whenever it barks.
Citronella is one of the main ingredients of perfume, the scent of which is disliked by all dog species. This makes the Citronella bark collar a highly effective method for preventing the incessant barking by some dogs.
The citronella collars were not without problems. Unless the microphone’s sensitivity is correctly adjusted, it picks up sounds of other dogs barking and may trigger its action which may not be fair to your dog.
