I’m sitting in the living room, and our dog Zoey walks past. Normally she would walk up to me and huff or stick her snout under my hand. Not this time; she heads directly for her crate.

My wife is upstairs running the water in the tub. Water running in the bathtub is a nightly ritual for our family, with two daughters to bathe. Normally this doesn’t bother Zoey, it’s always been this way.

But she knows, she always does; my wife is filling the tub for Zoey’s bath. Now the bathroom door is shut, and my wife has yet to pour any dog shampoo. So how the hell does she know?
