Again, it depends on the facts of the case. In most situations, working police dogs are exempt from dog bite laws as there is a certain amount of aggression that is expected in the line of work they do. However, if you were not the intended target of the police when the dog bit you or it bit you outside of the normal scope of its work, you could be eligible to file a claim against the department. Your attorney will let you know if you have a case after looking at all of the pertinent details.
