I have been so chased by friendly dogs so claim the owners. I carry pepper spray and have had to use it once on a dog. The lady said her dog was on "voice" command which is simply her standing still and screaming at her dog while it lunges at me. Afterwards you are the "dog" hater. Once I had a pit bull attack me at a campground, came without warning and circled me growling and snapping its jaws.  I stood still and did not make eye contact and the owner was a lady who then grabbed the dog by the collar and dragged it into her small car and then pounded the living daylights out of the dog while screaming at it.  If your dog chases people in attack mode spare me on how your dog loves all and the owner did not know what I did to provoke the "attack".
