Our farmhouse is very old and so is built next to a now very busy highway on Southern Eyre Peninsula. We have lost numerous pets to this road and were reluctant to adopt any more animals as a result. When my son-in law told me that there was a system that would keep dogs safe, I immediately researched and found The Dog Line, This has changed my world!!!! My new doggy will not go near the blue flags, even after receiving only ONE training walk! This system is incredible. I can leave the dogs home, with complete confidence that they will be alive when I arrive home from work. Thankyou.
