Have Dog Training Questions? Ask a Dog Trainer.
Im sorry you are having issues with your puppy acting out. I hope I can help. In addition to a verbal correction, you can discourage unwanted behavior during play by putting an end to the playtime and ignoring her or turning your back and not giving her attention until she is sitting politely. Stopping playtime will signal to her that she has gone too far and that something she is doing is not appropriate. Eventually she will learn that when she uses her teeth you do not play with her and that in order to get you to play with her she needs to be polite and keep her mouth closed. The old model of dog training involved dominance and the idea that dogs need to have a "pack leader" and a hierarchy. Newer thought is that dogs are less hierarchal than previously believed and do not need to be "dominated" to be trained properly. Dogs learn best when people use a combination of positive and negative reinforcement. Pushing her off, talking to her and otherwise giving her attention when she is doing something that we don't want her to do we are inadvertently reinforcing this bad behavior. Alternatively, when we ignore her we are clearly telling her that her behavior was unacceptable which causes her to change her behavior. I recommend working with a trainer in your area for the best results but in the meantime you can implement these suggestions to get started.
