Lissa Kucher and Cory Siem from Princeton have two Italian Mastiffs, Eli and Luigi. Lissa wanted to put in an underground fence, but doubted it would work for their breed since they have such a high pain tolerance. She called breeders and veterinarians all over the country and no one seemed to think that an underground fence would be strong enough to contain them. I assured her that our fence was the strongest on the market and that we have never had a dog we couldn’t contain. She gave us the opportunity to install the fence and prove to her that it would work. I’m pleased and proud to say that the dogs trained very easily and are respecting the fence and enjoying their large yard!!
