I'm babysitting my sister's dogs while she's in Europe (Hero and Stat). They both have separation anxiety and like to be within a few feet of me all day.
I find, as they trail me from room to room like I'm a parade float, that all it takes to turn that frown upside down is WiiiiiiiiiiiiiiiiiiiiiiiiiIII-ing like a pig whilst windmilling my arms.
Instant puppy Nirvana.
Huge canine grins and whipping tails.
Come to think of it, maybe that's how I threw my back out.
Well. It's worth it.
