Havahart® Expansion Kit for Fence Free Underground Dog Fence
Is 1/3 of an acre not enough for your property?? The Havahart® Expansion Kit gives you an additional 500ft. of boundary wire to create a larger containment area for your dog.
The Expansion Kit makes it easy to add additional roaming area to your electric dog fence and the 50 additional training flags makes it easy to train your dog to enjoy the new added space. The Havahart® Boundary Kit only works with the Fence Free Underground Dog Fence and additional boundary kits can be used to create a containment area up to 13 acres.
The easy to follow instructions make adding the extra boundary wire easy so you can create the containment area that fits the unique contours of your property.
