How to Make a DIY Dog Dig Box (And Why Your Dog Desperately Needs One)
Quick Answer
A DIY dog dig box gives your pup a dedicated place to dig, scratch, and bury treasures—so they can follow their instincts without destroying your yard (or your carpet). You can make a beginner version in about 20 minutes with a storage tub and pet-safe filling, then upgrade to a wooden frame for a more durable backyard setup.
Introduction
Does your dog turn your backyard into a construction site? Tear up the carpet? Launch excavation projects in your flower beds at 7am? You're not alone—and more importantly, your dog isn't misbehaving. They're just being a dog.
Digging is a deeply wired instinct for most dogs. Whether they're following a buried scent, creating a cool resting spot, or simply burning off energy, the urge to dig is as natural as barking or tail-wagging. The problem isn't the digging—it's where they're doing it.
A DIY dog dig box gives your pup a dedicated place to dig, scratch, and bury to their heart's content. Think of it as a sandbox, but for dogs. It redirects that instinct into a healthy outlet, adds mental enrichment to their day, and saves your garden (and your sanity). Best of all, you can build a beginner version in about 20 minutes with things you might already have at home.
What You'll Need (Beginner Version)
- 1 large plastic storage tub (at least 18" x 24" x 12" deep—bigger is always better for large breeds)
- Filling: clean play sand, potting soil, or a 50/50 sand-and-soil mix (enough to fill the tub about 2/3 full)
- A few of your dog's favorite toys or treats (to bury and discover)
- Optional: a piece of landscape fabric or an old towel to line the bottom
Beginner Version: Step-by-Step Instructions
Step 1: Choose Your Tub
Pick a sturdy plastic storage bin from any home goods or hardware store. It should be large enough for your dog to step into and comfortably turn around. For small dogs, a 12-gallon tub works great. For medium to large breeds, go for 20 gallons or more. Check that there are no sharp edges, cracks, or broken handles.
Tip: Look for tubs with lower sides so your dog can step in easily without having to jump—especially important for puppies, seniors, or dogs with joint issues.
Step 2: Add Your Liner (Optional, But Helpful)
If you're setting this up indoors or on a hard floor, line the bottom of the tub with a piece of landscape fabric or an old towel. This reduces mess if the filling is damp and makes cleanup easier.
Step 3: Fill The Tub
Pour in your sand or soil mixture until the tub is about two-thirds full. Play sand (available at hardware or garden stores) is a popular choice—it's clean, reduced-dust, and easy for dogs to dig through. A 50/50 sand-and-soil mix also works well and feels more natural underfoot.
Tip: Avoid fine-grain beach sand, which can clump between paw pads and cause discomfort. Look for play sand or construction sand at your local hardware store.
Step 4: Bury The Treasure
Before introducing your dog to the dig box, bury a few treats or small toys just below the surface. This gives them an immediate reason to start exploring and teaches them that the box is a rewarding place to dig.
Tip: Use sturdy rubber toys or firm biscuit treats rather than soft treats that can dissolve, spoil, or leave sticky residue in the sand.
Step 5: Introduce Your Dog
Place the dig box somewhere stable—outside on a patio or in a contained indoor area. Bring your dog over, let them sniff it, and encourage them with an upbeat voice: What's in here? Find it! Most dogs catch on within seconds.
Tip: If they're hesitant, gently scratch the surface of the sand yourself to show them what to do. Dogs often mirror their humans when learning something new.
Step 6: Introduce A Cue Word
Every time your dog digs in the box, say a consistent cue like dig! or find it! This teaches them that digging in the box is the approved behavior. If you catch them digging somewhere off-limits, calmly guide them back to the box and use your cue word.
Take It To The Next Level
Once your dog is hooked on their dig box, you can upgrade the setup into something more durable, polished, and stimulating—something that looks right at home in your yard.
What You'll Need For The Upgrade
- Untreated cedar or pine lumber (2x8 or 2x10 boards, cut to your preferred dimensions)
- Wood screws (1.5" or 2")
- Drill
- Medium-grit sandpaper
- Landscape fabric and staple gun (for the base)
- Fill: same sand/soil mix as the beginner version
- Optional: pet-safe, weatherproof wood stain or paint; plywood cut to size for a lid
How To Build It
- Plan your dimensions. A 3 x 3 frame works well for most medium dogs; go 4 x 4 for larger breeds. Cut four boards to your chosen length.
- Sand the edges. Run sandpaper over all cut surfaces and edges so there are no splinters your dog could pick up in their paws.
- Screw the frame together. Connect the four boards into a square or rectangular frame, driving two screws into each corner joint. The frame should stand 8-10 inches tall—deep enough for satisfying digging.
- Line the inside base. Staple a piece of landscape fabric along the inner bottom of the frame. This prevents filling from washing away, stops grass and weeds from growing upward, and keeps the base clean.
- Set it in place. Choose a shaded area of your yard—shade keeps the sand cool, which dogs find especially rewarding on warm days. Press the frame firmly into the ground so it doesn't shift during enthusiastic digging sessions.
- Fill and layer. Add 6-8 inches of your sand/soil mix. Bury a few toys toward the bottom layer, then cover with a final inch of fresh sand for that untouched surface effect.
Bonus Upgrades
- Add a lid. Cut a piece of plywood to fit over the frame and hinge it on one side. This keeps cats, neighborhood wildlife, and rain out when the box isn't in use.
- Finish the outside. Apply a coat of pet-safe, weatherproof wood stain to extend the life of the frame and give it a clean, intentional look in your yard.
- Create a treasure zone. Designate one corner of the box where you always bury something new each day. Dogs quickly learn that corner is always worth checking—and anticipating the find is part of the enrichment.
Pro Tips
- Refresh the box regularly. Add new buried items every few days to keep the experience exciting. Novelty is one of the key drivers of enrichment—the same buried bone loses its appeal quickly. Rotate toys, switch up treat types, or occasionally bury something with a strong scent (a piece of rope toy rubbed in peanut butter, for example).
- Supervise early sessions. Until your dog fully understands that the box—not the flower beds—is their digging zone, keep an eye on outdoor time and redirect consistently. A calm, cheerful over here! paired with walking them to the box is all it takes.
- Keep it cool in summer. If the dig box lives outside, position it in a shaded spot or lightly dampen the top layer of sand on hot days. Many dogs dig to regulate temperature, so a cool, damp dig box on a summer afternoon hits exactly the right instinct.
Why Your Dog Will Love It
Dogs dig for many reasons—and all of them are instinctual. Some breeds, like terriers, dachshunds, and Siberian huskies, were bred specifically to dig, so the drive runs especially deep. But even dogs with no working history dig to explore scents, cache food, regulate their temperature, or burn off restless energy.
A dig box satisfies that drive in a controlled, safe, and genuinely stimulating way. It provides the kind of mental engagement that's just as tiring as a long walk—so don't be surprised if your dog finishes a digging session and settles in for one of their best naps of the week. That's enrichment doing exactly what it's supposed to do.
Important Notice
Always use clean, pet-safe filling materials. Avoid potting soil mixes that contain fertilizers, pesticides, perlite, or added chemicals. If using outdoor topsoil, confirm it hasn't been treated with weed killers or lawn products.
Inspect the dig box regularly for anything your dog may have hidden—leftover food or items from around the yard can spoil or become a hazard. Do not leave young puppies unsupervised with large amounts of loose sand, as ingesting large quantities can cause digestive upset. Wash your dog's paws after digging sessions if the box is located outdoors and your yard is treated with any lawn products.
Make This Even Easier
If your dog is digging out of boredom or excess energy, pairing the dig box with a few other enrichment staples can make a huge difference—especially on busy days.
- Use a snuffle mat or treat puzzle for find it games indoors
- Rotate durable chew toys to keep novelty high — our Treat-Dispensing Robot Toy is great for keeping bored dogs busy between dig sessions
- Add a lick mat for calm-down time after digging
Your Gentle Next Step
Build the beginner dig box today, then use the same cue word every time your dog digs in it for the next week. Consistency is what turns this from a fun activity into a true approved digging zone.
Note
The guidance in this article is general in nature. Every dog has different energy levels, behavioral tendencies, and physical needs. If your dog's digging behavior is compulsive, excessive, or accompanied by signs of anxiety or distress, we recommend consulting with a certified veterinary behaviorist or professional dog trainer for personalized guidance.
