I'll have to think about the premises in this piece later, whether dogs have a whiff of time passed, what is their level of memory, and so on.
Just looked at the Michael S. Williamson photos. I'm a born fool for dog photos with or without captions - sometimes. I run pro and con and back on Wegman. In this case, the great dane one got me.
I've a tendency to prefer photos of street dogs for content depth, but not always, not exclusively at all.
