To give your dog enough space to roam without frequent feedback, we recommend you have ½ acre or more. The fence should be at least 80 feet wide at its narrowest point. Because your dog will hear tones 10 feet inside the boundary, if your fence is too narrow at any point, your dog will not be able to move freely without constantly hearing tones. 

Additionally, when planning your fence, account for GPS drift ーtypically between 3 to 10 feet near tall structures or heavy forest. It is important to include a 15-foot buffer zone between the boundary and any unsafe area, like a major roadway.
