Roger and team installed our electric fence back in early 2006... he helped me train our Australian Shepherd Cali with easy. In 2008 we acquired a Toy Australian Shepherd Foxy. Again, with easy Roger assisted us in training Foxy and for the past 10 years have had no issues with the fence. Equipment has continued to work and provide the protection that allows us to feel comfortable with our dog Foxy outside (she is a working dog and loves to just be outside). When there has been any issue with our fence (alarm sounds), call Roger and team - always a quick response and repair is on its way. I would recommend anyone looking for an invisible dog fence - use the BEST. Pet DeFence!
