Protecting pets. Preserving peace of mind. How? To put it simply, a wire is discreetly installed around your property to create an Invisible Boundary®. Our professional pet trainers effectively teach your pet these fence boundaries and avoidance behaviors so your pet clearly knows where they can and cannot go. Your pet’s custom programmed Computer Collar® delivers a warning tone and if needed a non-harming but effective static correction should they forget or try to test their limits.
