A dog's sense of smell is so acute it thinks a poop is a Picasso

I was doing laps with one of the regulars at the dog park, and we got to speculating about what goes through a dog's mind. For a dog, the sense of smell is allegedly 5000 times more intense than for us humans, but their eyesight is iffy. That's why you're never going to see a dog lingering in front of the Mona Lisa at the Louvre, but you will see them lingering over a random turd at the dog park. Speaking of which, I'm appalled at how many people don't notice when their best friend is taking a crap. I'm in the habit of taking the shovel along on the first lap, and there's usually at least half a dozen piles to be dispatched over the fence. I blame the dog owners who socialize by the gate, chit-chatting amongst one another, instead of minding their dogs.
