I understand the frustration! The owner needs to do the right thing and control the dog. Animal Control can only be in one place at a time. Until we walk a mile in the shoes of an officer from that department we can not judge their job. Lets support them, not throw them under the passing bus. Meet with them ask what you can do to help. Neighborhood watch, keep a list of problem dogs in your neighborhood, let your neighbors know you are doing that. Be an Animal Control friend, not a snyper trying to pick them off as they try to work. Just an idea!
