Barking is normal dog behavior but sometimes dogs bark because they are bored or lonely or to attract attention. Barking dog collars are used to help you control the dog's barking so that it only barks when there is danger or when you command it to stop barking or in other acceptable situations. You can use the no bark dog collar with other behavior reinforcing methods so that you can teach your dog to bark only at appropriate times, for example, when there is a danger, to warn off other animals, to ward off an intruder and in many other appropriate cases.
Aim to teach what acceptable barking behavior is. Use positive reinforcement so that the dog knows that barking in itself is not wrong. If you use negative reinforcement, it may lead to the dog's confusion and may even traumatize the dog as barking is a natural reflex and behavior. No bark dog collars are used to prevent your dog from unwanted barking. There are sound or sonic collars that will release a high pitched sound when your dog barks, citronella collars, which spray your dog with the citronella smell when it barks and electronic dog collars that will emit a small electric current onto your dog when it starts to bark.
Barking dog collars will help change your dog's uncontrollable barking and owners who use them say that they are effective. Once the dog has been trained and can respond positively to instructions such as stop, to stop barking, you can remove the collars and continue to use other behavioral reinforcements so the dog does not revert back to previous barking and behavior.
The electronic collars are the most recommended as they have different levels of stimuli so you can use a low level or increase it depending on what the dog needs. The electric stimulus does not hurt the dog, and in most cases the electronic dog collars stimulus is activated by the dog's vocal cord vibration so that it releases the stimulus when the dog is barking inappropriately. Citronella dog collars and sonic dog collars may be activated by other dogs' barking so they may not be very effective if you have other dogs or you live in the area with other dogs nearby.
The dog will soon learn that when it barks, it will be zapped with the static so that it knows that barking is unacceptable. You can then teach your dog the appropriate times to bark. For example, when the door bell rings you can bark to show your dog that it is okay to bark then. Teaching your dog obedience and discipline so that it stops barking on command will take time and patience and the barking dog collars will help you in your efforts. It is advisable that you seek a professional dog handler's opinion so that you know how and when to use the collars effectively. You may also learn other behavioral techniques that you can use with the collars so that your dog is able to stop barking on command.
