“Dog urine kills grass” is a common saying, and it just might be true. The grass is largely considered a victim of dog urine because it is a pretty serious issue, especially if you love your lawn. Dog pee is so high in nitrogen that it kills grass when it accumulates in a limited amount of time.

The results of dog urine on your lawn are comparable to those of nitrogen-rich liquid fertilizer. Fertilizer in small amounts is beneficial to your lawn, but too much kills it. To avoid burns, you must reduce the amount of nitrogen that comes into touch with your grass.

Let’s learn why dog urine kills the grass in your lawn and how you can prevent it.

Why does dog pee kill grass?

The nitrogen in your dog’s urine comes from protein breakdown because dogs are fed a lot of protein, their urine has a high amount of nitrogen. This is completely natural, and there’s nothing to be concerned about when it comes to your dog’s health.

Well, things are a bit different when it comes to your lawn’s health. A small amount of nitrogen activates lawns. Meanwhile, a large amount of nitrogen is concentrated in a small area, so when your dog continuously pees in the same location, it burns the grass.

Also, there is a myth that dog urine acidity burns the grass, but that is just a myth. Nitrogen in the dog’s pee is the main reason. Acidity has nothing to do with it.

Does diet affect dog urine damage?

Some research suggests that a high protein diet may lead to increased nitrogen levels in dog urine. As a result, greater grass damage. So if you’re concerned about your lawn’s health, consider switching your dog to a lower-protein diet.

The majority of dry and wet dog foods available on the market are highly processed. You may create your doggie diet at home if you want a genuinely fresh one. According to many pet parents, making your dog food at home is more cost-effective than buying dog food at the supermarket.

Does water intake affect dog urine damage?

The amount of water your pooch drinks will not significantly impact the nitrogen level in their urine. However, if your dog is drinking lots of water and still urinating frequently, you should visit a vet to check any health issues with your 4 legged buddies.

Does breed affect dog urine damage?

No scientific evidence suggests that the breed of your dog has any impact on the level of nitrogen in their urine and, as a result, the amount of grass damage they may cause.

How to identify dog urine damage in the grass?

Depending on the condition of your lawn, dog pee may cause one of two types of damage: Brown spots indicate that your lawn is receiving too much nitrogen. On the other hand, dark green spots indicate that your grass isn’t getting enough nitrogen.

Do you have brown or dark green patches in your grass? Here’s how to tell if pup urine is to blame.

Brown spots

If your grass is yellowing or decaying, it’s dead. Yellowing or browning in the grass might be caused by various factors, including lawn fungus and grubs living in the soil. Your grass isn’t to blame after all for your dead grass.

You should look for the following characteristics if the brown spots (or yellow spots, if they aren’t completely dead yet) came from urine:

  • A ring of dark green grass encircles the perimeter of the kill area.
  • It’s difficult to remove grass once you’ve planted it.


Green spots

Your dog’s favorite potty spot hangouts might occasionally turn dark green rather than brown. Dark green spots suggest that your soil lacked nitrogen before, and the dog’s urine supplied the nutrients your grass required to thrive as healthily as possible.

In this circumstance, the urine stains are, in fact, superior to the rest of your lawn. Apply a high-nitrogen fertilizer to the remaining portion of the soil so that all of your grass can be lush and dark.


How to prevent dog urine damage to your lawn?

Here is a list of things you can do to prevent your dog from damaging your lawn:

1- Train your dog to pee in a specific area: If you can get your dog to pee in a specific area of your yard, you can reduce the overall amount of nitrogen they’re putting into the soil.

2- Use a grass pad or rocks: A grass pad will help to absorb the urine and protect the lawn underneath. Rocks can also be used as an effective barrier between your dog’s favorite potty spots and the grass.

3- Provide your dog with plenty of water: If your dog is well hydrated, they’ll produce less urine and be less likely to damage your lawn.

4- Feed your dog a diet low in protein: A diet low in protein will help to reduce the level of nitrogen in your dog’s urine.

5- Use an enzyme cleaner: If your dog has already caused damage to your lawn, an enzymatic cleaner can help break down the urine and minimize the yellow or brown patches.

6- Use urine-resistant grass type: If you live in a climate that’s hot and dry, consider using a urine-resistant grass type. This will help minimize the amount of nitrogen your dog’s urine puts into the soil.

7- Have your soil tested: A professional soil test can help identify any nutrient deficiencies in your soil, which may contribute to the damage caused by your dog’s urine.



Q: Will my lawn grass grows back after dog urine damage?

Yes, your lawn grass will grow back after dog urine damage as long as the roots haven’t been damaged.

Q: Can I use a product to eliminate the dog’s urine smell?

Yes, there are many products available that can help remove the smell of dog urine from your lawn. For example, you can use a mixture of vinegar, dish soap, and hydrogen peroxide.

Q: What should I do if my dog is constantly urinating on my lawn?

If your pup is constantly peeing on your lawn’s grass, you should take them to the veterinarian to rule out any possible health problems. Once your veterinarian has ruled out any health problems, you can begin to work on training your dog to pee in a certain area of your yard.

Q: Is there anything I can do to prevent my dog from urinating on my lawn?

You can choose several things to prevent your dog from urinating on your lawn, including using a grass pad or rocks, providing your dog with plenty of water, feeding your dog a diet low in protein, and using urine-resistant grass type.

Q: Why do dogs eat grass?

There are many different reasons dogs eat grass, including to help with digestion, get rid of parasites, and relieve boredom. Some pups may also like to eat grass because they enjoy the taste.

Final Words

Keeping your lawn healthy is important, but so is taking care of your furry friend. With a few little adjustments, you can have both!
