Dog bark collar is a training collar that can let dog owners train their dogs not to bark. While it resemble a traditional collar, it emit some negative stimulus like an unpleasant scent, static shock, or high-frequency sound when your dog barks. When dogs bark excessively, not only is it exhausting for them but it also spikes their heart rate and wrecks the peaceful state of your home, so a suitable bark control collar can help you to manage your dog's behaviour. It is important to note that you should remove the dog bark collar before playing with your dog. The activity may cause your dog to bark, which could lead to him associating the play with the static correction. Never leave it on for more than 12 consecutive hours.
