Read www.bullyonline.org. first and foremost. Gather evidence, and report them to your HR dept when the time is right. Be warned that they are extremely paranoid and are character assassins so keep your paperwork, thoughts and feelings to yourself. Do not gossip about them, Do not gossip about anyone else either as they will use that against the person AND you to isolate. They will use personal info to destroy your confidence and credibilty.

It may be that it is playing with it. If you dog is a puppy this is most likely to happen. Otherwise the best way to stop them from doing it (if you want them to) is to use positive reinforcement (catch them in the act, tell them no or get them to stop attacking it. After a few seconds of good non attacking behavior, reward them with a treat.)
