Review on Enhanced PetSafe PIF00-12917 Stay and Play Wireless Dog Fence System for Dual Dogs by Robert Bridgewater

We bought this because we moved into a house without a fenced yard. It was very easy to set up and train our dogs to recognize boundaries. The markers proved to be very durable and survived the winter. Both collars are easily adjustable to fit our large dogs (Golden Doodle and Lab mix). The excess strap was torn by our dog but the strap itself has lasted over 8 months and is still strong. Our dogs are stubborn so we couldn't take their collars off but the shock is enough to keep them from crossing the line. Highly recommended!
