My wife and I had a fence installed for our dog Denver at our home in Chagrin Falls. We live in the Village and have a very small lot so in order to maximize Denver's yard space they provided us with an invisible fence that starts the correction at the fence line. This means that our dog can lay in his favorite spot in the house with his collar on and not get zapped even though the fence is buried less than 2 feet way on the outside of the house. The instruction and service was perfect! We (including Denver) could not be happier! I would highly recommend!
