Thanks to Contain-A-Pet for helping me secure my two large Labs. One had a habit of exploring the neighborhood and being found close to a main highway. Since the installation of the underground fence system I have had no problems with him taking his trips. Both Labs have adjusted and enjoy a 3 acre lot by running and playing and I have gained peace and confidence that they are safe. Thanks to Jake and You for your professional job and follow ups. What a great investment!
