Ditto. Even in the Muggeropilis of DC, when walking my pup I worry most about off-leash dogs at the park.

And so pepper spray is clipped next to her water bottle.

Haven't had to use it but have flashed it a couple times to impress upon an aggressive German Shepherd's owner and a vicious Giant Schnauzer's owner, that I was serious about their dogs being restrained.

Some dog owners are clueless and their dogs, and other people's dogs, suffer for it.
