You walk outside with a cup of coffee, enjoying the morning air, and then you see it. A fresh pile of dirt. A crater. A literal tunnel leading right under your property line. Dealing with dog holes in fence lines is basically a rite of passage for pet owners, but honestly, it’s incredibly frustrating. Your yard looks like a construction site and your dog is one squirrel away from a neighborhood-wide search party.
Digging is instinctual. It's not because your dog is "bad" or trying to spite your landscaping budget. Dogs dig to cool off, to chase scents, or because they’re bored out of their minds. According to the ASPCA, certain breeds like Terriers or Huskies are genetically hardwired for this behavior. They aren't just making a mess; they're fulfilling a biological drive. But that doesn't mean you have to live with a porous perimeter.
Why Your Dog is Turning Your Fence Into a Swiss Cheese Project
Before you go buying ten bags of concrete, you’ve gotta figure out the why. If it’s a Beagle, they’re probably smelling a rabbit on the other side. If it’s a Northern breed in the middle of a July heatwave, they’re looking for the cool, damp earth beneath the surface. Sometimes it's separation anxiety. Your dog sees the fence as a barrier between them and you, so they try to go under it.
I’ve seen people try those "scat mats" or bitter sprays. Honestly? They rarely work for a determined digger. If a dog wants out, a little bad taste isn't going to stop them. You need structural solutions that change the physical reality of the fence line.
Hardware Cloth and L-Footers: The Pro Secret
This is probably the most effective way to handle dog holes in fence areas without spending a fortune. Hardware cloth is basically a heavy-duty wire mesh. You don't just put it on the fence; you create an "L" shape.
Basically, you attach the wire to the bottom of the fence and then lay the rest of it flat on the ground, extending inward toward your yard. You can bury it under a thin layer of soil or grass. When the dog tries to dig right at the base of the fence, their paws hit the wire. They can't get through it. They get frustrated and stop. It's a physical deterrent that doesn't hurt the dog but makes digging impossible.

Make sure you use galvanized wire. If you use cheap stuff, it’ll rust out in two seasons and you’ll be right back where you started, except now you’ll have rusty shards in your dirt.
Concrete Footers and Curbs
If you’re building a new fence or have the budget for a serious weekend project, pouring a concrete curb under the fence line is the "nuclear option." It’s permanent. It’s clean. It works. You dig a narrow trench along the fence line and fill it with concrete, essentially extending the "wall" of your fence several inches underground.
It’s a lot of work. You'll be sore. But your dog will never, ever dig under that fence again.
Rocks, Boulders, and the Power of Landscaping
Sometimes you don't need a construction crew; you just need some heavy decor. Large river rocks or flat flagstones placed along the perimeter are great. Dogs generally won't try to move a 20-pound rock just to get to the dirt underneath. Plus, it looks a lot better than a bunch of wire mesh.
There's a specific technique here. You want to partially bury the rocks so they can't be easily nudged aside. If you just toss some gravel down, the dog will just dig through the gravel. It’s basically just "fancy dirt" to them. You need large, heavy stones that create a physical "no-dig" zone.

The Psychological Fix: Why Physical Barriers Aren't Enough
If your dog is digging because they’re bored, they’ll just find something else to destroy. Maybe they’ll stop digging under the fence and start chewing on your siding.
Experts like Dr. Ian Dunbar have long advocated for "digging pits." Think of it like a sandbox for dogs. You pick a corner of the yard where it's okay to dig, bury some toys or treats there, and encourage them to go nuts. When they dig there, they get rewarded. When they dig at the fence, they get a "no" and are redirected to the pit. It sounds simple, but it’s about giving that energy an outlet rather than just trying to suppress it.
- Increase Exercise: A tired dog is a quiet dog. If they’ve had a two-mile walk, they’re less likely to spend an hour excavating the yard.
- Mental Stimulation: Puzzles, frozen Kongs, and nose-work games can tire a dog out more than a walk can.
- Company: If your dog only digs when you're gone, it's likely anxiety. Leaving them outside for 8 hours alone is an invitation for "escape projects."
Addressing the "Critter" Problem
Sometimes the dog holes in fence aren't even started by the dog. Groundhogs, moles, and even stray cats can start a small hole that your dog then decides to "expand."
If you see smaller tunnels or signs of wildlife, your focus shouldn't just be on the dog. You might need to address the pests first. Using peppermint oil or non-toxic deterrents for small mammals can keep the "bait" away from your fence line, which in turn keeps your dog from trying to follow them.
I remember a neighbor who spent weeks yelling at his Lab for digging. Turns out, there was a family of rabbits living right under the shed on the other side of the fence. The dog wasn't trying to escape; he was trying to get to the "squeaky toys" on the other side. Once the rabbits moved on, the digging stopped overnight.

Temporary Fixes That Actually Work (And Some That Don't)
If you're in a rental or need a fix today, you can use tent stakes to pin down the bottom of a chain-link fence. If the fence has "give" at the bottom, the dog will push their nose under it and then start digging. Removing that "give" makes the task much harder for them.
What doesn't work?
- Cayenne Pepper: It’s cruel. It can get in their eyes and cause serious pain.
- Filling holes with poop: This is an old wives' tale. Most dogs will just dig a new hole two inches to the left.
- Yelling after the fact: Dogs don't have a concept of "I'm being punished for what I did twenty minutes ago." If you don't catch them in the act, you're just a person shouting at a dog next to a hole.
Building a Dig-Proof Future
If you are looking at long-term solutions, consider the "Coyote Roller." While usually used to keep things from jumping over a fence, variations of this rolling bar can be placed at the bottom to prevent paws from getting a grip.
Also, look at your fence material. A solid wooden privacy fence is often better than chain link because the dog can't see what they're missing. If they can't see the mailman or the neighbor's cat, the "drive" to get to the other side drops significantly. Out of sight, out of mind.
Actionable Next Steps
If you're staring at a fresh hole right now, here is exactly what to do:
- Fill the hole properly. Don't just kick dirt back in. Pack it down with heavy rocks at the bottom, then a layer of chicken wire or hardware cloth, then the dirt on top.
- Evaluate the "Why." Is it hot out? Is there a squirrel? Are they bored? Fix the underlying issue while you fix the dirt.
- Secure the base. Use landscape staples or tent stakes to pin the bottom of the fence fabric to the ground so it can't be lifted.
- Install a barrier. Buy a roll of galvanized hardware cloth this weekend. Bend it into an L-shape and secure it to the fence and the ground. It's the single most effective DIY fix for most suburban yards.
- Audit the environment. If your dog is left alone for long periods, consider a dog walker or more interactive toys to burn off that "digging energy" before it turns into a hole.
Managing dog holes in fence lines is about persistence. You might not win the first round, but by combining physical barriers with a little bit of "dog psychology," you can keep your pup safe and your yard intact.
