We have a dog and we are concerned that she'll jump the 4' chain link fence from the retaining wall made out of recycled 6x6 timbers. The problem is that there is a wood privacy fence that is in line with the chain link as we once had a pool in the area that we will now have a much needed universal design veggie garden. The old wood fence will go at some point, but we can't afford to tear it down now. We are thinking of horizontal Ipe, or something with copper and wood in some type of Greene and Greene or Craftsman design. Any ideas?
