Joe and Courtney Ende from Taylor Ridge Illinois have a busy household. They live on a large acreage and wanted to give the dogs a lot of space to play, yet limit them from the wooded area since Joe and his son are deathly allergic to poison ivy. We closed in about two and a half acres and trained all three dogs in a couple of hours. They are loving their freedom! DG Postscript — since their install Joe and Courtney have referred a couple sets of friends who have put in systems as well! Thank you!!
