Pepper spray for dogs, any recommendations - UPDATE

Just don’t tell me you are running around with mace in your shorts because it is safer. And if at all possible let me know where you will be, so I can be somewhere else.

I always run with pepper spray clipped to my shorts. Along with a phone. Just to clarify, I run in an upscale suburb of a city of 4 million, not the boonies. Still, in the recent months, there have been robberies and rapes of runners in our area. I think anyone running anywhere with less is foolish.
