Good for you, Penny!Talk about Thread creep, though...
Had a very similar experience with a Rottweiler in my home town. Ended up winning as I was bigger and scarier than it was. Stared it into submission, and then was chewed out by the owner for 'frightening his poor dog'. We exchanged a few choice words on the subjects of guard dogs being loose on public streets (and maybe one or two on the owner's matrimonial lineage), and I toddled on my happy way to have a few words with the local police.
