A great and fun way to house train your dog is to train her to communicate to you when she needs to go out to potty is by teaching her to ring a potty train bell. This is best taught after your dog seems to prefer to go outside to potty and you would like to give her a good way to communicate that to you. The dog bell works especially well for dogs who only have only a few accidents or have accidents by the door. Teaching your dog to ring a bell prevents her from needing to resort to such "uncivilized" behavior as scratching on the door or barking to tell you to let her out.
When it's time to potty train your puppy, you can do more than just teach her that she needs to go outside. You can also train your puppy to ring a bell any time she has to go out. Hearing this bell will alert you that your puppy needs a potty break. It has the added advantage of discouraging your puppy from scratching or barking when she needs to go out.
