I dislike kennel myself but when I first got into dogs I visited a yard that had the best kennel set ups I have ever seen. He had a about two acres fenced in with ten foot tall chain link fence then his 20+ dogs was each on a ten ft long chain with a 6 ft circle kennel around each dog. In the yes I knew him not a single dog got loose. No yard accident or mistake breeding, or dogs stolen. That in itself saids a lot about his setup
