Why the brown spots happen: this post says dog urine burns grass because of nitrogen (ammonia), not because it’s “acid.” Small nitrogen can help grass, but too much kills it.
Fastest fix: dilute the spot with water right after your dog goes. The article says running the hose for about 10 seconds over the area can lower the chances of burn.
Best long-term prevention: create a designated dog potty area (gravel, mulch, pavers, or turf), choose more urine-tolerant grass types, and fertilize less where your dog goes so you don’t stack nitrogen on top of nitrogen.
4 Tips to Prevent Brown Spots Caused by the Dog in Your Lawn
In this quick guide you will learn the 4 best tips to get rid of brown spots in the lawn caused by your dog.
It’s true, there are very few drawbacks to owning a dog.
Dogs provide unconditional love, companionship, and even protection!
Unfortunately, the green lawn sings a different tune—a sad one at that.
Ugly, brown spots caused by the loving creature’s #1 bodily function often make themselves known.
So, how do you prevent dead spots in the lawn? And repair those brown spots made by your dog? If you’re booking mowing and you have a dog in the yard, read this first: Managing Lawn Care with Pets.
Simply put, the brown spots are due to the break down of protein from your dog's diet.
Since dog diets are high in protein, there will always be high levels of nitrogen—similar to nitrogen-rich liquid fertilizers purchased at the local Seed & Feed store.
That translates to over 73 million dogs that call the lawn their personal throne. That's a lot of bathroom acreage for man’s best friend.
To counter all of the brown spots across the nation, below are the 4 best tips for keeping the lawn looking healthy and green.
Tip #1 Dilute with Water
Watering the lawn area immediately after the dog has done its business can help dilute the nitrogen.
Running the hose for just 10 seconds over the spot will help lessen the probability of the nitrogen killing the lawn.
Get this! You can also "pre-dilute" your dog.
How? Encouraging your dogs to drink more water will dilute the nitrogen internally.
BE AWARE! This technique will cause more trips outside and could yield to an accident in the house if your dog is left alone for longer periods of time.
Tip #2 Build a Dog Pen
Constructing a non-grassy designated area will certainly prevent brown spots in the lawn.
A few examples of materials that can be used:
Gravel,
mulch,
cement or pavers,
or artificial turf area in the yard makes it pee-proof.
How do you potty train the dog to use his new area?
It may take a little time to train the dog to use that area, but it is totally possible.
Positive reinforcement and praise goes a long way, leading to the dog automatically heading to that area when it’s time to go.
Pro Tip! You can make these areas visually appealing to humans by placing potted hostas, ferns, or other greenery around the area.
Tip #3 Plant a The Right Type of Grass
Havingthe right kind of grasscan also contribute to how easily and frequently these brown spots show up.
For example,fescue and ryegrassare the most resistant to nitrogen due to the genetic makeup of the roots.
Unless the dog is only allowed to go outside during the spring and summer. Bermuda and bluegrass are very sensitive to nitrogen and most susceptible to brown spots.
Tip #4 Fertilize Less
Dressing the lawn with less fertilizer will reduce the chances of brown spots; especially the areas that the dog does urinate on.
Even small amounts of fertilizer may contain enough nitrogen to kill the lawn when used in combination with the dog’s contribution.
If fertilization is needed, only areas outside of the dog’s peeing perimeters should be fertilized.
So is there a foolproof way stop brown spots in the lawn?
There is one...
Building the dog a designated area is the only option that has the highest probability for success.
It may take a little time to train the pooch, but it can be done.
Bottom Line on Brown Spots Caused By Dogs
It’s possible that keeping your lawn free of brown spots could take a back seat to making sure your dog does not exercise his rights inside the house.
Additionally, multiple tips may need to be implemented concurrently for the lawn to stay healthy and flawless.
Either way, these steps should help you enjoy a brown, spot-free lawn.
