dog pepper spray

I love to run and love to take my own dog for a walk, but where we live there are just WAAYY to many dogs roaming around. I love dogs, but do have a slight fear of other people dogs roaming around. Where we live there is no leash law (in the county). I can’t walk my own dog (who is fenced in) because around the corner both ways are dogs that run after you.

Anyway I want to start running again I have a treadmill, but really there is nothing like getting up early and going out for a run not to mention I would like to take my own dog out for runs or walks. Where can I purchase a spray that will make the dogs leave me alone yet not hurt the dog?
I found on amazon Halt dog repellent. Anyone ever use it?
