We have a leash law here, so no dogs should be out roaming. Inevitably some are. (Maybe they are very clever and can get out of their yards.) The meanest dog on my commute is also a dustmop looking thing, but I'm not sure what it is. Maybe a shih-tzu mix or something. It's securely fenced, though. The other day I did hear a very mean bark and heard a rustling in the bushes and out...runs...this medium-sized dog that was seriously the fattest dog I've ever seen. I actually considered finding its owner and offering to help it exercise.
I also pass a parrot on my commute. Its cage is on the front porch of a house and it sits on top and squawks. If that bird ever came near me, I'd probably wreck myself trying to get away!
