So today, I put the dogs in the dog pen, and Belle was immediately out and about behind the house. I got her in and went out to check, and I have TWO sections of damaged dog fencing now, one at the bottom of the run and another at the top. Apparently something running up the hill hit the lower fence hard, breaking the section clear of it's connectors and flattening it pretty decently. That something then ran up the hill and pulled the second section down, probably trying to climb out.
Whatever it was, it was bigger than a German Shepherd. I suspect one of the local deer.
Excuse my blunt talk, but I've really fucking had it with those things lately. This is going to take a while to fix, and probably require some new fencing material too. I really don't need this right now.
