Are you tired of your dog’s constant barking? If your dog does not stop yapping even after you spend extra hours training it to behave well, it is time to consider getting a bark collar for your pooch. Most people would prefer not to have their dogs wear a bark collar, but they quickly change their mind when the collar solves the problem. Getting the right bark collar is very important so you should spend a little time shopping around before you buy one. In order to give you a head start, we present you here some choices that people prefer when they buy a bark collar. The Sonic Bark Collar The sonic bark collar is one of the most popular anti-bark collars available in the market today. The sonic collar detects when your dog is barking and then reacts by emiting a very high pitched sound. The objective of the sound is to distract the dog from whatever he was barking at and make him focus on the sound. The high pitch sound produced by the collar is inaudible to the human ear so you won’t be bothered by its sound. Some people think that the exposure to a high pitched sound is harmful to the dog, but in reality it's as harmful as listening to the highest note on a piano is to you. In any case, the sound from the collar is activated only when the dog barks, and since the sound causes the dog to stop barking, it won't last long. Spray Collar The spray collar is designed to squirt out citronella spray unto the dog’s snout every time the dog barks. Citronella is used because dogs are known to dislike it a lot. When dogs finally realize that their own barking is what triggers the citronella spray, they start to reduce their barking. The other side of the coin is that sometimes the smell of citronella can linger around for much longer than the owner intended it to. Some dogs might believe that the punishment still continues and might not make the connection with the barking. If your dog is extremely sensitive or irritable to citronella, then this type of bark collar is not your best choice. Electrical Shock Collar The shock collar is very well known for its effectiveness, as well of being infamous among some dog lovers for its method of correction. The collar's method consists of detecting the dog's barking and then reducing it by administering small electric shocks to the dog's neck. The electric shock is painless to dogs, but some people think it can be cruel.
