Barrie Police are trying to track down another dog after another resident suffered a bite. A woman in her 60s says she was nipped on the arm Wednesday afternoon while walking near Big Bay Point and Dean Avenue. It was a Rottweiler-type dog being walked by a man in his 30s. Police want to ensure the dog has had its shots so the woman can get the proper treatment. There was a similar incident last weekend in the north end of town.
