Innotek Rechargeable In-ground Pet Fencing System 18g Wire SD-2100-HD

I've had this system and moved three times with it. My two dogs are 70 - 75 lbs and have done GREAT with this system. The freedom to open the door & just let the dogs run in the yard is a beautiful thing! Take proper time to train the dogs with this system & you won't be disappointed. Have friends that have tried other brands without as much success.
