With all this staying at home we wanted a way for our old little dog to be able to be in the front yard with us but she tends to wander off. This is a great way to do that since our deed restriction won’t allow fences in front yards. It was simple to set up after a rain storm and you can hardly tell it’s there. The charge stays a long time and the shock does not hurt her, just redirects her. I like that it has 2 collars so we can always have one ready for her. It’s great having her in the yard with us as we relax or garden.
