If you have a dog and some grassy land, chances are you have urine spots peppering that lawn of yours. Those brown spots are caused by the grass-killing nitrogen present in dog pee.
Dog urine ruins lawns the same way too much nitrogen-rich liquid fertilizer does. You can use a little fertilizer to make your lawn look great, but don’t overdo it; otherwise, it can kill your grass.
We’ve put together some of the best ways to naturally prevent dog urine from killing grass so you can enjoy your lawn again without having to look at all those ugly brown spots.
The 6 Methods on How to Prevent Dog Urine From Killing Your Grass Naturally
1. Use Your Water Hose to Dilute the Urine

Appropriate For | Small to medium-sized yards |
Effectiveness | Good |
Difficulty level | Medium |
A good way to prevent dog urine from killing your grass is to spray the lawn after your dog goes pee to dilute the grass-killing nitrogen. While this is an easy method to try that doesn’t take much time, you will have to spray your grass every time your dog pees if you want to prevent lawn damage.
This method won’t work in the dead of winter when your hose is put away for the cold weather. It’s also more difficult to do if your yard is big and your dog pees all over and often.
- Good way to dilute nitrogen
- Easy to do
- Inexpensive
- Must be done every time your dog pees
- Not possible in winter
- Not for large, expansive yards
2. Increase Your Dog’s Water Intake

Appropriate For | Any size lawn |
Effectiveness | Good |
Difficulty level | Easy |
The more water your dog drinks, the more diluted the nitrogen will be in their pee. That’s why you should encourage your dog to drink more water. Place water dishes around your yard so your dog is more apt to drink when they’re outside playing and snooping around.
While this is an effective way to reduce those brown urine spots, there’s no way to force your dog to drink water, so this method isn’t foolproof. This is another method that won’t work so well in the wintertime when your dog’s drinking water will turn to ice when placed out in the cold.
- Easy to do
- Works well at diluting nitrogen in urine
- Can’t force a dog to drink
- Not easy to do in cold weather
3. Train Your Dog to Urinate in a Designated Area

Appropriate For | Any size lawn |
Effectiveness | Excellent |
Difficulty level | Medium to high |
One of the best ways to prevent dog pee from killing your grass is to train your dog to do their business in a non-grassy area. If you don’t have a patch of mulch or gravel in your yard, consider adding one.
While this method takes time and patience, it’s the best way to keep your lawn spot-free! Consistency is key with this method. You should be present every time your dog goes outside so you can show them where you want them to pee. Use lots of praise when they do their business in the new pee spot.
If you don’t already have a mulch or gravel area in your yard and need to put some in, this method can be costly. It also requires muscle power, so be ready to roll your sleeves up and get to work!
- Very effective
- Will keep your lawn spot-free
- Takes time and patience
- Can be costly
- Must be consistent in your training
4. Give Your Dog a Grass-Saver Supplement

Appropriate For | Any size lawn |
Effectiveness | Good |
Difficulty level | Easy |
You can give your dog a grass-saver supplement that will bind with the nitrogen in their urine to reduce brown spots in your yard. While this isn’t the most effective way to get rid of all the pee spots on a lawn, you should see fewer brown spots if you follow the directions on the label.
You should get approval from your vet when you want to give your dog a dietary supplement. Many dog owners find these supplements effective, so it’s an option worth checking out, so long as it’s determined safe by your vet.
- Breaks down grass-killing nitrogen in pee
- Easy to use
- Can get costly
- Should get vet approval first
5. Plant Different Types of Grass

Appropriate For | Small lawns |
Effectiveness | Good to excellent |
Difficulty level | Medium to high |
If you have a lawn consisting of grass that’s very susceptible to dog urine, like Kentucky bluegrass or Bermuda grass, consider replacing the grass. Grass that stands up better to dog pee includes fescue grass and ryegrass. The good news about these resilient grasses is that most are low-maintenance, which means less work for you!
While replacing your grass costs money and takes time and labor to do, it’s a great way to get your lawn back in top shape. If you want to go this route, speak with the experts at your local garden center. They’ll be able to tell you what kind of grass is the most resistant to dog pee and a type that’s appropriate for your environment. This method is the easiest and cheapest for small lawns.
- Reduces brown spots
- Less maintenance
- Costly
- Time-consuming
- Not practical for large yards
6. Use Natural Paramagnetic Rocks in Your Dog’s Water

Appropriate For | Any size lawn |
Effectiveness | Good |
Difficulty level | Easy |
Many homeowners are turning to natural rocks to prevent dog urine spots from killing their grass. You can find these unique paramagnetic rocks at online pet stores.
These lawn-saving rocks are 100% natural and sourced from the ground in Australia. They work to eliminate the harmful toxins in dog urine that damage grass. You simply drop a few rocks in your dog’s water and watch as your grass starts looking better with time.
It typically takes several weeks of use before you start seeing noticeable improvements in your yard so be patient if you choose this method. Also, you should get approval by your vet before doing this. Note that while some people claim that these work well, the science isn’t out yet to fully back this, so results vary.
- 100% natural
- Easy to do
- Gradually cuts down on brown spots
- Takes time to see noticeable results
- Can get pricey with long-term use
- Should get vet approval first
- Science doesn’t fully back this yet
Keeping Your Grass Nice and Green
Once you find the right solution for preventing dog urine from killing your grass, you’ll want to keep that lawn looking pristine. Take your dog out for walks more often so they’re peeing less on your lawn. It’s also a good idea to use a sprinkler regularly on your grass to keep it well-hydrated and healthy.
While dog poop isn’t as harmful to your lawn as dog urine, you should still pick it up. When piles of dog poop are left to sit on a lawn, they can kill the grass underneath. So, arm yourself with lots of poop bags or a proper pooper scooper and keep your yard neat and tidy!
Conclusion
You can own a dog and keep a nice lawn that’s free of brown urine spots if you are willing to do some work. Be patient with your dog, your lawn, and with yourself as you work to get rid of those ugly brown spots in your grass. Pick the right method above that’s suitable for your yard and get to work restoring that luscious green lawn!
