What To Put On The Ground In A Dog Run: 7 Surfaces And What To Avoid

As an Amazon Associate I earn from qualifying purchases.

A dog run is a fenced strip of garden where your dog can be outside safely while you are nearby. The ground you put in it decides how comfortable, clean and safe it is, so it is worth choosing before you build.

This page compares seven surfaces and lists what to avoid. Where there is a published source we quote it, mainly the AKC, AKC yard-safety guide and RSPCA. Our notes on cost and upkeep are our own judgement, not veterinary advice, so talk to your vet if your dog has joint, skin or paw problems.

Plan The Run First

Location And Shade

Put the run where you can see and hear your dog, such as a side yard, and out of the hottest sun. The AKC says “providing shade in your yard is incredibly important to prevent life-threatening canine heatstroke”, and that you should “try to never leave a dog in a yard for any lengthy period of time unattended”. A run is for supervised time, not for leaving a dog out all day.

Add a roof, shade cloth or a sun umbrella, and keep fresh water in a bowl that cannot tip. Our guide to a dog kennel and run covers the structure, and our page on a heavy-duty ground anchor covers tethering safely.

Size And Fence

We have not found a published size standard for a dog run, so go by your dog: it should be able to walk, turn, stretch and lie down comfortably. A bigger run is better for an active dog. The fence should be tall and sturdy enough that your dog cannot jump, climb or dig out, so check the base for gaps and watch for a dog that tests it.

Seven Dog Run Surfaces Compared

Heat is the main thing to check on any hard surface. The RSPCA gives a simple test: “If the ground is too hot to touch with your hand for five seconds, it’s too hot for paws!”

1. Concrete

• Pros: easy to scoop and hose down, long-lasting, and it does not turn muddy or let your dog dig.
• Cons: hard to lie on, cold in winter, and hot in summer. The AKC warns that heat-absorbing hardscaping can burn paws.

If you choose concrete, add a raised wooden bed or a rubber mat as a comfortable resting area, and keep part of the run shaded. Use the five-second hand test before letting your dog out on a sunny day.

2. Rubber Matting

• Pros: softer underfoot, drains well and is easy to clean.
• Cons: one of the dearer options, and dark rubber in direct sun can get hot, so test it with your hand.

3. Dirt Or Grass

• Pros: cheap, soft and cooler in summer than hard surfaces.
• Cons: turns to mud in rain, wears away quickly under a busy dog, and needs reseeding.

If you use a weedkiller, fertiliser or pest treatment on grass, read the label for how long to keep your dog off, and ask your vet if you are unsure.

4. Synthetic Grass

• Pros: soft, stays clean and drains.
• Cons: dearer to install, can get hot in direct sun, and needs regular rinsing after toileting.

5. Wooden Platforms

• Pros: comfortable to lie on and easy to move; over gravel they drain quickly.
• Cons: wood can rot or splinter over time, so check it regularly. Choose timber that is safe for animals, because dogs chew.

6. Composite Decking

• Pros: looks like wood but resists weather and rot, and is easy to clean.
• Cons: dearer, and dark boards can get hot in the sun, so use the hand test.

7. Gravel Or Crushed Stone

The AKC says “a benefit of gravel is that it is easy to clean, and the liquid drains through it quickly”. Its vets also warn that it “can get stuck in paw pads and in between toes, and can get too hot without adequate shade”, and that it can be a choking or blockage risk for dogs that chew. Pea gravel or smooth, rounded stone is gentler than sharp chippings, and it is a poor fit for puppies and chewers.

The AKC suggests pavers as an alternative: “paving stones might be a better option because they tend to be flat and stay cool to the touch”. It also notes that concrete pavers “prevent dogs from digging holes and tracking mud inside the house”.

Surfaces To Avoid

• Cocoa bean mulch. The AKC calls it “the worst offender”: “It contains theobromine (the ingredient that makes chocolate dangerous for dogs) and caffeine. Eating a lot can lead to heart rate increases, arrhythmia, hyperactivity, and seizures.” It names “pine straw” as “a suitable alternative pet-safe mulch”.
• Wood chip mulch. The AKC says mulch “can also cause splinters in their paws”, so it is not an ideal run surface.
• Treated timber you cannot identify. Dogs chew rails and posts, so use timber sold as safe for animals.
• Bare, sunny hard surfaces with no shade. These are the ones that burn paws in summer.

If your dog eats something from the run and you are not sure what it was, ring your vet straight away rather than waiting for symptoms.

Paw Care Products For Outdoor Runs

Dogs that spend time outside can wear their pads and nails. These four items cover paw protection and basic care. Details come from the Amazon listings; we have not tested them, so check the size chart or description before you order.

1. Water-Resistant Dog Shoes With Anti-Slip Sole

The listing describes water-resistant shoes with two reflective fastening straps and a rugged anti-slip sole, in eight sizes. Measure your dog’s paw and follow the listing’s size chart rather than guessing by breed, and introduce them slowly indoors first.

2. RC Pets PAWks Dog Socks

A lighter option for short outings or for dogs that dislike shoes. Check the size chart on the listing and take them off if your dog chews them.

3. Dermoscent Bio Balm For Dry Paw Pads

The listing describes a 50 ml skin-repairing balm for dogs. If your dog’s pads look cracked, sore or red, talk to your vet before relying on a balm.

4. Safari Stainless Steel Nail Trimmer

Nails that grow long on hard ground can make walking uncomfortable. Trim small amounts often, and ask your vet or groomer to show you how if you have not done it before. See also our guide to dog care.

The Bottom Line

A good dog run has shade, water and a surface that stays cool, drains and does not hurt paws. Many owners combine surfaces, for example pavers or a rubber mat for the main floor with a raised bed for resting. Avoid cocoa mulch, keep time in the run supervised, and talk to your vet about any paw or joint concerns.
