Bests & Worsts Reviews from Amazon

Ordered for protection from loose dogs in my neighborhood. There are some big, scarey dogs that I worry could get out of their yards, when I walk my 20lb terrier. Sure enough, last week two big black German Sheppard sized dogs, broke through the dilapidated fence and charged us. They got to within two feet of us when I let them have it, with about a 3 second burst. It stopped them in their tracks and sent them running. Am certain they would have attacked if I had not had this with me! Can still at least half full but just ordered a second can, just in case.
