We have a difficult pie shaped property and the installer Joseph did a great job installing the Hidden Fence through our thick ivy and steep backyard hill. Stephanie (the trainer), was great with our two little dogs (plus a cat). The fence works completely as advertised. By following the training process over three days our pets were completely trained to the fence. Since our hidden fence was installed we’ve also had a pet door installed. Now, our pets are completely free to roam our entire yard and we aren’t worried about them at all. They don’t go anywhere near the flags. A bonus, our neighborhood has a large number of dog walkers and joggers throughout. Thanks to the DogWatch Hidden Fence our pets no longer go after those who venture near our front yard.
