We handle dog bite cases.  Unlike the urban myth, there is no "One free bite rule" in Florida.  An owner is are responsible for what their dog does, and must take reasonable care.  Also, the prescence of a "Beware of Dog" sign as sold in all stores, provides no legal immunity at all.  The Florida legislature has written a very specific set of guidelines about dogs, and that sign does not meet the guidelines.   In all our years, none of the lawyers at the Hockman firm has ever seen a "beware of dog" sign that met the legal requirements of warning.
