I am installing a six foot tall chain link fence in my backyard for my large German Shepherds. I have an installer that is going to give me a good deal on some industrial strength fence with twisted top and bottom. It is much thicker and sturdier that regular chain link. I was thinking that the twisted end on the bottom would prevent the dogs from trying to get under the fence to escape. I would also have it installed so the bottom is basically touching the ground, which would help it not move. Has anyone ever had a twisted bottom chain link fence for their dogs and how did it work for you? My only concern would be the dog getting his foot cut on the bottom if he was trying to dig out. I guess he would probably only try it once though. Any thoughts?
