Dogs will bark on occasion. Constant barking is a sign that there is a problem that you need to remedy. Among the many reasons that dogs bark are social isolation, territorial behavior, protective behavior, and separation anxiety. Until you can figure out what is the cause of your dog’s constant barking, the proper use of bark collars works well to help alleviate you and your neighbor’s frustration by minimizing or interrupting the barking. There are basically three types of bark collars; Citronella, High-frequency (aversive sound), and electric shock collars. Many stores that sell pet products will have one, two, or all three types. You possibly could consider hiring a professional dog trainer to help you with the problem. If you have exhausted all avenues to prevent or minimize the barking, you might want to consult with your veterinarian about a debarking surgery. This might be an extreme solution, but preferred over getting rid of your dog.
