What is a Containment System?
A Containment System is the cost-effective alternative to traditional fencing. You create an in-ground hidden fence using a boundary wire. The detailed instructional video and/or DVD guides you through the easy-to-follow self-installation process.
When your dog is wearing a containment collar and approaches the boundary area, he hears a warning tone. If he continues toward the boundary, he receives a harmless but effective electrical stimulus that reminds him to stay in the "safe" part of the yard.
You can also use a containment system to block off areas such as gardens, swimming pools, or anywhere else you don't want your dog to go. If you have a traditional fence, but a dog who likes to dig under or jump over it, installing the boundary wire just inside the perimeter of the fence could be your answer.
Most importantly, these systems provide freedom for your dog to run AND peace of mind for you.
