K-9 units around the world are trained for a “find-and-bark” approach, according to the International Association of Chiefs of Police. However, police dogs in the US are trained for a “find-and-bite” approach because barking has been deemed too “unrealistic.” This can cause serious harm to bystanders. In one example alone, in Pierce County, Washington, a police dog attacked a 53-year-old woman as it was tracking a suspect.
