Pet Supplies Delivered offers three types of anti-barking dog collars or devices. All deliver a correction that is triggered by barking and stops when the barking stops. However, they differ in the type of correction delivered. Electronic collars deliver an electrostatic shock if the collar senses the throat vibrations that accompany barking. Ultrasonic devices and collars respond with a high-pitched tone that is triggered by vibration or sound. Citronella collars respond to the sound of the barking by releasing a puff of citronella in front of the dog's face.
