Shun dog parks or other areas where my dog is likely to come in contact with off-leash dogs.
Always carry a breaking stick
Keep my dog away from any dog that is remotely likely to provoke an aggressive response in my dog.
Ouch!! The only 2 creatures I have a hard time understanding their existance is mosquitos and porkies. Most bird hunters I know shoot porkies on sight, me included. Only in locations where legal of course. Although most bird hunters with dogs that I know do so in all states with the SSS rule. Shoot, Shovel and Shutup. Personally I don't want another dog to dig one up even if dead and throw them high off the ground in the fork of a tree.
Dog snapped at the woman then ran at cop. Whether or not the situation was serious, the dog was unleashed on a crowded street and aggressively moving toward the perceived threat. The cop had a moment to react and made the right choice. The pepper spray may have been unnecessary.
Why that drugged out guy has a dog is beyond me, but what are you going to do?
