EXtreme Dog Fence Stubborn Dog System - 5 Dog Underground Containment With 2000ft Wire

Got a Houdini dog that thinks boundaries are suggestions? This eXtreme Dog Fence 'Hyper' system is specifically designed for stubborn, large, or bull-headed dogs that laugh at regular containment. The collar has 8 different correction levels you can set individually for each dog - from gentle reminders to more assertive corrections for those determined escape artists. The system covers up to 4 acres with the included 2000 feet of heavy-duty boundary wire, and you can bury it or attach it above ground with the included sod staples. Each collar fits necks from 6 to 28 inches, so it works for everything from determined small dogs to massive breeds. The transmitter creates a signal field from 6 inches to 10 feet high, and you get 5 collars, 50 flags for training, and all the connectors you need. American-made with US-based support 7 days a week - these guys actually answer the phone when you have questions! The wire is UV-resistant and designed to last over 20 years, even submerged in water. Seriously, if you've tried other systems that your dog just powered through, this one might finally be the solution.
