This is the 2nd Invisible Fence we had installed by Mike. Mike is awesome! He brought his dog, Hazlitt, with him this time to help with the training. I only have positives to say about Mike. Anyone can do the installation. But Mike goes above and beyond with training your dog. Even with the second installation at our new home Mike still spent considerable time with our Dog. And of course our Dog loves Mike and Hazlitt. We are 110% satisfied. Not sure you can get better service than what Mike offers!! Oh and the fence is genius. Our rescue Hound Dog has never once gone through it. She has had many temptations, i.e., rabbits, deer, cats, other dogs, etc. But she will not go through it. For the doubters of the invisible fence. Me, I hated the thought of fencing my yard with wood etc and the maintenance of it. The Invisible Fence is the perfect solution. As I said this is our 2nd install by Mike. If you ever had doubts that it won't work. Your dog would not learn the boundaries, etc., call Mike. He will train your dog and you on on to use it. I definitely was a doubter. Now I am a believer! Call Mike and give your Pet the freedom of roaming your yard. And give yourself the peace of mind that your pet is safe and having fun.
