Dirty dog

Today's challenge was "dirty" - after a few days of rain, everything around my place is dirty and I had some nice ideas for photos for today - however, it hasn't rained for ages! I shouldn't complain though!
Since my little girl is still in Germany on her holiday, I sent her four dirty photos per Skype and she chose this one of Isgaard's paw after a good dig next to the waterbowl outside for today's blip.
