This requires more investigation

I took this shot last Tuesday when Louise was in the office. That's Greg peeking in the background and Louise is standing on the desk because she is more interested in the food I was eating than in the food I gave her. (See the uneaten carrot sticks and snap peas at her feet.)

Basically, it is just a goofy little moment caught over lunch time. Shortly after this Louise and I headed out for a brief walk - it was warmer that day so I opted to take her on shorter, but more frequent walks. It seemed to work out well, with Louise not getting quite so overheated as she would with a longer walk in the afternoon sun.
