A root Cellar?

I went to the bank the other day and the teller asked if I had a dog now.  I said, "yes, but he is only allowed in the fenced pasture when I'm not with him.  Did you see him on the highway?"  She said, "Oh no.  He was in the yard just digging away and tossing dirt everywhere.  Then he would run around the hole he was digging and just seemed to be having the best time.  He must still be a puppy but he looked pretty big already."

So, needless to say when I got back home I let the dog out of his kennel and we went out to the front pasture. Thor gets to spend a lot of his day out in the front pasture/garden area.  He has some of his toys out there with him and the goats don't know the gate between the areas is open so they leave him alone.    Sure enough he has a couple of holes dug there.  Both of them are already at least two feet deep.  Maybe he is digging for water or he knows I have wanted a root cellar to store veggies in.  That isn't quite the location I had in mind for the root cellar.  Realistically, however, I suspect he is trying to get the gopher or mole family that has been making gardening in that area a real challenge for the past few years.  Go Thor!  I hope you catch them.
