Sometimes, man's best friend is your lawn's worst friend, leaving you wondering how to fix dog holes in the grass. Dogs love to dig, especially young dogs under the age of 3 or terriers and similar hunting dogs. The resulting holes in your grass don't just look unsightly, but also attract weeds, cause soil erosion and pose a risk for falling. Thankfully, a quick fix to repairing your lawn problem is as simple as a game of fetch.
Dodge the Dog
Before you fix dog holes in the grass, it's crucial to solve the root of the problem. Dogs often dig because they're restless or bored, so twice-daily walks combined with readily available lawn toys such as a chewy ball or bone can ease the situation. If your dog still won't stop digging, invest in dog training that teaches him not to dig, or provide a dedicated digging zone, like a child's sandbox filled with your dog's favorite toys, that's more attractive to a curious dog than your manicured lawn.
Fix Dog Holes
Once the hole in your grass has been cleaned up, fill it with topsoil. Use enough dirt that the hole is now filled and level with the surrounding soil in your yard. Tap down the soil surface with a spade or piece of plywood so that the soil surface is firm but not hard and compacted.
Measure the Bare Patch
Using a measuring stick, the side of a piece of plywood or a similar straight edge as a guide, trim and cut the edges of your lawn surrounding the bare soil area that was once a hole in your grass. Remove and discard the trimmed grass edges to create a patch of bare soil surface that is as close to a perfect square as possible.
Measure two sides of the square and multiply them together to get the square foot measurement. While it may seem counterproductive to remove the healthy grass around the exposed dirt surface, this makes it easier for your final step: adding a new square of living sod.
Patch Up Your Problem
Reseeding and similar methods of lawn repair can be effective to fix dog holes, but they're also time-consuming and work-intensive. Living sod, available from most garden stores and nurseries, is one of the fastest and best methods of lawn repair. A sod square covers the soil immediately to instantly improve your lawn's appearance and protect against soil erosion and weeds. It also reduces how long you need to keep your dog out of your lawn to just two weeks, while waiting for seeds to take root and establish themselves can take a month or more.
Simply buy a sheet of sod that matches the size of the dirt patch where you had to fix dog holes and the grass you have. Lay the sod on the soil surface and trim as necessary so there's no exposed soil but also no overlap between the sod and the surrounding grass. Press the grass down so it has good soil contact and water once a day for a week.
