So, we put this fence in in the last year or so. Now the big one has figured out how to get out. He is not digging, and I highly doubt he is jumping it, i would like to think he is too fat to squeeze through, but I am leaning toward this being the case. Any thoughts on how to keep the bars from spreading? I hoped they had clips or something that can be added, but I haven't found anything. I am considering some sort of flat stock screwed to the pickets 18"ish from the ground. I need to see if i can get a camera out there or something... Unfortunately, the little dog won't narc on him.
