A bark control device for deterring a dog from barking. The bark control device includes a vibration dampening material forming or covering at least a portion of the bark control device housing. The vibration dampening material reduces the transfer of vibrations through the bark control device housing by reducing the vibrations to levels undetectable by a bark sensor, by preventing the production of vibrations having characteristics sufficiently similar to a bark, and/or by inhibiting the propagation of such vibrations through the bark control device housing. The vibration dampening material of the housing reduces the occurrence of corrections to the dog due to vibrations emanating from a source other than a bark by the dog.
