Introducing a great tool for pet owners who want to train their dogs to signal when they need to go outside. This set of potty bells from Caldwell's Pet Supply Co. is perfect for most size dogs and comes with two sets of bells. The bells hang 12 inches from the floor and are easy to hang from the door knob - really, really easy.

These potty bells are attached to black nylon webbing. The bells and tag are shiny chrome, and the bells have a pleasant tone.
