My dog was digging in 2 spots. One was at the edge of the patio, the other by a small Japanese Maple. There seemed to be nothing of interest in either spot, yet the digging persisted. I eventually fenced off those areas (with gardening fence - nothing expensive or elaborate), took my dog out on a leash away from the digging areas, planted grass seed, let the seed grow in, then stopped using the leash and removed the fence. Once I had the area properly grassed, and the spot where the digging was grown back, the interest in digging seemed to end and I don't think my dog even remembers that he was once obsessed with that spot.
I know this seems like a lot with the fence, and leash and what not. In the event that you are not as patient as I, the above suggestion with pepper is a very positive one from what I have heard. The smell will deter the dog, especially if he gets in there. Then the taste will also distract him. Plus, you are not damaging the ground or your hard with any chemicals.
