Spring and fall are prime time for yard projects across Michigan. Lawn care crews arrive to aerate and overseed, neighbors plan new patios and privacy fences, and homeowners plant trees, build garden beds, or install sprinkler systems. For most yards, that is just a to-do list. For homes with a hidden pet fence, it is also a risk.
Your underground dog fence wire is buried just a few inches below the surface, which makes it easy to nick, cut, or pull out of place without anyone noticing. A single break can stop the whole system from working, and your dog may be the first to find out. The good news is that most wire damage is preventable with a little planning. This guide explains which projects put your wire at risk, how to protect it, and what to do if something goes wrong.
Why Yard Projects Put Your Fence Wire at Risk
The wire for an electric dog fence forms a continuous loop around your property. That loop must remain unbroken for the signal to travel. Because the wire sits close to the surface, anything that digs, slices, or pulls at the soil can damage it. Contractors and lawn crews cannot see the wire, and unless they are told where it runs, they have no reason to avoid it.
Damage is not always dramatic. A small nick may not cause trouble right away, but moisture can get in and cause problems later. That is why the best protection is making sure your wire is known, marked, and respected before work begins.
Common Projects That Can Damage Underground Dog Fence Wire
Watch out for any work that disturbs the soil, including:
- Core lawn aeration: Aerators pull small plugs from the turf and can catch a shallow wire.
- Dethatching and slit seeding: Machines that cut into the soil can slice through wire near the surface.
- Edging and sod cutting: Edgers and sod cutters work close to the roots and can reach buried wire.
- Fence posts and deck footings: Post-hole augers and digging for footings are among the most common causes of wire breaks.
- Irrigation and drainage work: Trenching for sprinkler lines, French drains, or downspout extensions can cut straight across the wire path.
- Planting trees, shrubs, and garden beds: Even hand digging can hit the wire if you do not know where it is.
- Patios, walkways, and grading: Excavation and leveling disturb a wide area at once.
Step-by-Step: Protect Your Wire Before Work Begins
A little preparation goes a long way. Use this checklist before any project starts:
- Find your layout: Ask your installer for a diagram of the wire route, or take photos of your flags and layout when the system is installed.
- Mark the path: Use flags or marking paint along the wire route so everyone can see where it runs.
- Tell your contractors in writing: Let lawn care companies, landscapers, and fence builders know that a pet fence wire is buried in the area.
- Call 811 for public utilities: MISS DIG 811 marks public utility lines before you dig. Keep in mind that private lines, such as a pet fence wire, are typically not marked this way, so you still need to flag your own wire.
- Consider rerouting: If a project will sit directly on the wire path, ask a professional about rerouting the wire before work starts.
- Test the system afterward: Once the project is done, test your collar and boundary before letting your dog out unsupervised.
What to Tell Your Lawn Care Company
Many homeowners hire a lawn care company in spring or fall for aeration and overseeding. Because crews move quickly across many properties, it is easy for a detail to slip. Share your wire layout before the first visit, mark the path, and ask the crew to avoid the wire route or adjust the depth of their equipment. If the company is not comfortable working around the wire, it is better to know ahead of time.
Timing Matters in Michigan
In Michigan, aeration and overseeding typically happen in early spring or early fall, while fence, deck, and patio projects ramp up once the ground thaws and stay busy through summer. These are also the busiest times for contractors, so it helps to plan early. A spring or fall system check pairs nicely with seasonal lawn work and gives you confidence that your boundary is intact.
Keep a copy of your wire layout somewhere easy to find, such as a photo folder on your phone, so you can share it quickly with any contractor who visits.
Signs Your Wire May Have Been Damaged
After any yard project, stay alert for these warning signs:
- Your collar no longer warns or corrects in the usual places
- The transmitter sounds an alarm or shows an error
- Your dog starts crossing the boundary after being reliable
- Disturbed soil, cut turf, or exposed wire along the boundary
- A system that worked before the project but not after
If you notice any of these, keep your dog on a leash or in a secure area and call for a system check. Waiting can lead to escapes and bigger repairs.
How Wire Break Repair Works
The good news is that a damaged wire can usually be fixed without redoing the whole yard. A technician typically uses specialized equipment to locate the break, exposes the wire in that area, and makes a waterproof splice. After the repair, the system is tested to confirm the signal is continuous and the boundary is working again. Because wire break repair involves locating a hidden problem, it is generally best handled by a trained professional rather than guesswork.
Plan Ahead: Update Your Layout After Big Changes
If you add a pool, expand a patio, build a shed, or redesign your landscaping, your boundary may need to change as well. Updating the wire layout during or right after a project keeps your pet safe and saves money compared to emergency repairs.
Yard projects are exciting, and with the right preparation, they do not have to threaten your dog’s safety. Know where your wire runs, mark it, tell your contractors, and test the system afterward.

Frequently Asked Questions
Yes, but you should plan ahead. Core aerators can catch shallow wire, so mark the wire path, tell your lawn care company, and test the system once the work is complete.
The wire is usually buried only a few inches below the surface, which is why digging and aerating can damage it. Ask your installer about the depth used on your property.
MISS DIG 811 marks public utility lines. Private lines such as a pet fence wire are typically not marked this way, so you should flag your own wire and share the layout with your contractors.
Yes. Providing the layout and marking the wire route before the first visit helps crews avoid accidental damage. Putting it in writing is even better.
Post holes and footings are common causes of wire breaks. Mark the wire route, consider rerouting the wire before work begins, and test the system afterward.
Warning signs include a collar that no longer reacts where it used to, a transmitter alarm, disturbed soil near the boundary, or a dog who suddenly starts crossing the line. Call for a system check if you notice any of them.
In most cases, yes. A technician can locate the break, expose a small section of wire, and make a waterproof splice. The system is then tested to confirm the boundary is working again.
Definitely. Test the collar and boundary after any project that disturbs the soil, and keep your dog supervised until you are confident the system works.
Yes. A professional can reroute the wire to match a new layout, which is usually easier and less expensive than waiting for a break and repairing it.
Contact your fence provider as soon as possible. In the meantime, keep your dog on a leash or in a secure area until the system has been checked.
