A pet accessory pendant is provided which houses components for a pet accessory, bark control device, containment fence receiver, remote trainer, pet locator, and the like. The pet accessory pendant is mountable to animal collars of various sizes, lengths, widths, and thicknesses and comfortably hangs in a pendant fashion and minimizes pressure points on the animal. The pet accessory pendant is attachable to and detachable from the collar without removing the animal collar from the animal, reducing the need to adjust the fitment of the pet accessory pendant for each use. The pet accessory pendant allows a single animal collar to be converted between a general- purpose animal collar and an animal collar with attached pet accessory. The ease of attachment and detachment allows for quickly changing pet accessories, leashing the animal without removing the animal collar to detach the pet accessory, replacing the battery, or modifying the pet accessory controls.
