[Quiet Man Cometh]

The dog might have been being territorial as well, which also doesn't necessarily mean agressive. I've been charged by dogs on the street a couple times. I keep and eye on them but usually just go about my business and not bother to react. Both occasions they stopped barking a few feet away and walked off when they saw I wasn't reacting to them. Dogs can interpret running as an invitation to chase. If that's what they're looking for they will quit when they realize you aren't playing along.
