PetSafe Basic In-Ground Fence System

Install the system in about a weekend by setting up the transmitter and burying wires around your yard. The system can cover up to 5 acres. It comes packaged with 500 feet of wire and 50 flags (to cover approximately 1/2 acre) - additional wire and flags are available for larger yards (sold separately). You'll place flags around your yard and train your pet where his new yard boundaries are in fun, quick training sessions over the next 2 weeks. Most pets learn their new boundaries quickly. If your pet gets too close to the yard edge, the waterproof receiver collar reminds your pet with a warning beep, followed by a safe, gentle static correction if he continues. System includes one pet collar to contain one pet, but you can add an unlimited number of pets by purchasing an extra collar for each pet (sold separately).
