Gotcha! all four caught unawares

The magic word 'dinner?' caused all four to gather and look hopefully at me  - they always hear the faint click as the iPad  is turned off so they knew I was still busy - but I had sneakily switched to 'camera'. 
Happy Christmas to all our doggy contacts from the 'gang of four' (left to right - Bess, Mystic, Merlin and Sophie on the sofa)
