I live on a 5-acre property that’s bordered by a busy street on one side, and the small fenced area in the backyard just wasn’t enough for an active dog to really move around. With the Spot0n system, I can be anywhere else on the property and still let the dog explore the full area within the electronic perimeter fence. We also switch to a different GPS layout when we go to the lake cabin, which is easy to set up. The neighbors are happy too, since our dog no longer wanders over to their deck and eats their dogs’ food. The tracking feature does work well, though we don’t need it much because the dog learned the system pretty quickly and doesn’t try to get out often.
