Three Dog Night: One

So this is an attempt at being witty. Piper looks lonely here, but in fact it's been a Three Dog Night in our house. We're watching Riley, my in-laws border collie who is smarter than I am. 

So, Rex + Piper + Riley = 3 different dogs waking up to go outside at 3 different times in the night.

Here's a bonus photo of Riley watching The Antonio treatment on HGTV.
