How to Stop a Dog That Digs Holes in the Lawn

Give your dog a legal place to dig, tire the body first, and manage the lawn for two to three weeks. That combination stops more digging than scolding or filling holes ever will.

Here is the premise I ask owners to test before we change anything else: digging is normal canine behavior trying to solve a problem. Cooling off, boredom, prey sounds, escape, or just the sheer fun of shoveling dirt with paws. Punishment after the fact does not teach a different choice.

I counseled a family with a 3-year-old, 62-pound mixed-breed dog who had excavated a trench along the fence every afternoon while everyone was at work. The yard was large, the dog was friendly, and the owners were convinced he was angry about being left alone. We mapped a week on paper: 20 minutes of morning fetch, alone from 9 to 4 with no midday break, then frantic zoomies and digging from 5 to 6. The pattern pointed to stored energy and habit, not spite. By day 10 on a new plan with a morning walk, a frozen food toy at noon, and a sand box by the fence, the old trench stayed untouched for four straight days.

Read the holes before you fill them. Location and timing tell you the motive.

Dogs that dig cool pits under shrubs on hot afternoons are thermoregulating. Dogs that dig at the fence line, especially when neighbors or squirrels are active, are patrolling or trying to reach something. Dogs that dig scattered shallow craters after long days alone are usually under-exercised. Dogs that dig only when left alone, with vocalizing, drooling, or escape attempts at doors, may be anxious, and that pattern deserves a closer look at Boredom vs Separation Anxiety: How to Tell the Difference.

The same sorting applies indoors. If your dog also shreds bedding or baseboards, compare notes with Is My Dog Chewing Out of Boredom or Anxiety?.

Digging is an outlet problem, not an obedience problem

Exercise comes first. Most adult pet dogs need at least 30 to 60 minutes of active movement daily, split into two sessions, plus sniffing and training that tires the brain. A tired nose digs less. Add a 15-minute sniff walk, three 3-minute training reps for sit, recall, and settle on a mat, and one food puzzle during the high-risk digging hour.

Manage the lawn while you retrain. Pick up feces, lay chicken wire flat under mulch in garden beds, block the favorite corner with planters for three weeks, and supervise yard time. Fill old holes, tamp them firm, and water lightly so loose soil is less rewarding.

A 14-month-old, 48-pound terrier mix I followed kept outsmarting every deterrent. The owners had tried cayenne, vinegar, and filling holes with his own stool. He just moved six feet over and dug deeper. Three weeks in, the log showed the truth: every blowout happened between 4 and 5 p.m., right before dinner, after zero daytime activity. We shifted dinner into a scatter feed on the patio, added a 20-minute tug and fetch session at 3, and gave him a single approved digging pit. He chose the pit within five days because it paid better.

Deterrents fail when the need stays unmet.

Teach where to dig instead of trying to get to zero

Build a digging box. It sounds silly until you see it work.

Pick a 3-by-3-foot corner with loose sand or topsoil, bury biscuits, rubber toys, and a frozen Kong just under the surface, and lead your dog there on leash. Cue “dig,” praise scratching in that spot, and let your dog find the prize. Practice five minutes daily for a week. When your dog heads to the old lawn spot, interrupt calmly, redirect to the box, and reward heavily.

Keep nails short, provide shade and fresh water nearby, and rotate buried prizes so the box stays more interesting than the lawn. For escape diggers, add a solid barrier: bury L-footer wire 12 inches deep along the fence, check gates for gaps, and never leave a fence-pacing dog unsupervised.

Anxious patterns need a different lens.

I think about a 6-year-old, 34-pound spaniel who only dug at the back gate on days the owner worked late, by day 12 of a work trip with a pet sitter. No barking on camera, but pacing, panting, and one deep hole by the latch. More running made her more wired, not calmer. We cut the long evening run to a calm sniff walk, added a predictable departure routine, left a worn shirt and a long-lasting chew, and asked the sitter to do two brief potty breaks instead of one long lonely stretch. The digging stopped when alone time felt safer, not longer.

That is the tradeoff owners miss: arousal and anxiety look busy, but they do not resolve with more intensity.

Where calming support fits beside training and movement

Structure comes first, ingredients second. Sleep, predictable exercise, and a clear digging outlet may help support a calmer baseline over two to four weeks. Calming herbs and amino acids are backup for that plan, not a substitute for it.

Keep expectations preventive and narrow. For the remaining species, evidence is derived mainly from preclinical studies or traditional use, as noted in Biomedicines. A systematic review analyzed multiple RCTs and concluded that ashwagandha has a moderate positive impact on stress reduction and cognitive performance, according to Cureus. The L-theanine literature is also limited, except for one study on psychotic anxiety (SMD = 0.54; 400 mg/day for 8 weeks), as summarized in Molecular Psychiatry.

Talk with your veterinarian if digging pairs with panic, self-injury, or sudden behavior change, or if you are considering any supplement alongside medication or for a puppy, senior, or dog with liver, kidney, or thyroid disease.

Management wins the first week.

Your owner checklist for the next 21 days

Track baseline for three days: time, place, triggers, and what happened right before. Add movement in two daily blocks with sniffing and short training. Block old holes and supervise yard time. Build and load the digging box daily. Keep bedtime, meals, and departures consistent. Recheck at day 10 and day 21 and keep what lowered the count.

You are not trying for a perfect lawn by Sunday. You are building a calmer routine that makes the box the easy choice.
