PetSafe Wireless Dog Fence

Keep your pet contained without having the hassle of burying wires or installing a pet fence!

Waterproof collar adjusts to fit 6–28" necks (uses 6-volt lithium battery, included). For dogs 8 lbs. and up. Comes with power adapter for transmitter, 50 training flags, test light tool and optional long contact points for long-haired dogs.
