[Dailydrool] Smelling the roses

[Riche Churchill via Dailydrool]

Has anyone ever explained why dogs like to roll in stuff we'd rather 
they didn't? With their super-sensitive noses, you'd think it would 
result in sensory overload, wouldn't you? And why horse droppings, cow 
patties, or worse yet, long-since dead things? Why do they WANT to smell 
like that? Isn't it dangerous? One would think a fierce predator would 
be attracted to the smell of horse or cow (yum!) with a side of dog...
It's a puzzlement. Somebody go google.
