Meet Dennis & Sherry Crist

Dennis and Sherry Crist are fence people first: they have owned Crist Fencing LLC for over 20 years, installing chain-link, aluminum, and vinyl fencing across the tri-state area, and added Dog Guard underground pet fencing in 2013. It is a true family operation, with their sons working alongside them in the business. The Crists know dogs as well as fences: they have raised German Shepherds of their own for over 40 years, and every system is custom-fitted to the pet it protects. From their home base in Darlington, Wisconsin, they serve 25 counties across Wisconsin, Illinois, and Iowa.

Dog fence questions, answered for Tri State Dog Guard

Where does Tri State Dog Guard install underground dog fences?

Tri State Dog Guard covers the corner where Wisconsin, Iowa, and Illinois meet, working from a base in Darlington, Wisconsin. Coverage includes a block of Wisconsin counties reaching north to Marathon and Portage counties and west to La Crosse, plus Dubuque and Jackson counties in Iowa and Boone, Carroll, Jo Daviess, Ogle, Stephenson, and Winnebago counties in northern Illinois. The business has been installing Dog Guard systems since 2013.

How does Tri State Dog Guard figure the price of a buried dog fence?

Price follows the property. Yard size and shape, how many dogs, and what the wire has to cross each play a part, and this territory serves everything from village yards in Darlington to dairy farms with long lanes and bluff-side acreage. Hilly ground can change how the wire is routed, which the estimate accounts for. You receive the estimate before any work starts, with financing available on larger jobs.

Can an underground fence be installed on the steep hills and bluffs of the Driftless Area?

Yes, buried wire handles Driftless terrain well. Southwest Wisconsin, northeast Iowa, and northwest Illinois escaped the glaciers, which left steep hills, bluffs, and uneven ground where building a physical fence is slow and costly. Boundary wire follows the contours instead of fighting them, running up slopes and around rock, with every route planned around the land as it actually lies.

Does Tri State Dog Guard service and repair fences after installation?

Yes. Fence locating and repair are core services, so a wire cut by field work, landscaping, or a new culvert can be found and fixed quickly. A battery plan keeps fresh receiver batteries coming on schedule, boundaries can be reshaped as your property changes, and trade-ins of existing systems from other brands are available if you are replacing aging equipment rather than starting from scratch.

Can a small dog use an underground fence?

Yes, Dog Guard systems work for dogs from about 4 pounds and up. The receiver weighs under 2 ounces, so even a toy breed carries it comfortably, and correction levels adjust to match the dog wearing it. Small dogs on rural properties often need the boundary most, since they are the ones at risk from roads, machinery, and whatever wanders out of the timber.

Can Tri State Dog Guard keep pets out of certain areas inside the house?

Yes. Indoor pet containment pairs with the outdoor system. Small indoor transmitters create off-limits zones around trash cans, countertops, a nursery, or the mudroom where boots and barn coats live, and the same receiver your dog wears outside enforces them. Farm households often use an indoor zone to keep dogs out of a single room without shutting doors all day.
