We're so sorry for any misunderstanding! As mentioned in the description, this system has a circular radius of around 90 feet from the transmitter in every direction. Depending on the size and shape of your house and yard, we cannot guarantee whether this would cover your entire yard. We do apologize for any inconvenience this may cause.
If you need a solution which would cover your entire yard, a wired/in-ground fence may be a better fit. If you would like to discuss this option with us, please get in touch with us! Our number is 1-800-732-2677, and our hours are Monday through Friday 8 A.M.- 7 P.M. EST.
