Whenever Timber would play-bite with me, I would squeal like a puppy. Soon she realized that it was hurting me. Whenever she got excited, she would also jump all over and run around like crazy. If she jumped, I would bring my knee up to push her away, and when she ran around, I would just ignore her. She still has her moments, and I just look at her quietly, and tell her "What do you do?" in a warning voice. She will sit down in front of me and wait.

Hope I helped
