It's a giant dog

Trip to Montreal in my early 20s. Went with close friends who were a couple, we stayed in this cheap place and shared a room. Midnight walk one night to this 24 hour bagel bakery. I think this happened that night.

We saw this huge dog walking in the night by itself. You don't see that a lot, dogs usually aren't that large, dogs are usually on leashes. There was something terrifying about the thought of this gigantic creature alone by itself in the Montreal night.

I think each of us said one part of the three part utterance:

Its a giant dog

and its all alone

oh my god.
