Me too... but I seriously doubt that it was.

There is a beautiful park near my home, but it's hard to enjoy it because of all the idiots and their dogs.
I have witnessed so many bad situations involving dogs, that I am uncomfortable around ANY dogs in public places.

Blast, it sounds like you handled the situation in the best way. I believe you showed the proper restraint that a responsible gun owner should; but I am glad that you had that option (gun) available.
