As a proud dog parent, you want the best care for your beloved dog.

The internet is packed with information to get you to spend money. Proud Dog Parents wants to combat this by offering free information to dog owners that will improve your dog's health.

This week a dog expert answers the question: Will dog wee kill grass?

What if your dog pees on the grass?

If you have a canine, then chances are your lawn has many brown spots and dead grass. This happens when the dog pees on the lush green grass and kills it. Dog urine is high in nitrogen, which is well-known for burning grass when concentrated amounts are collected over time.

The effects of your dog’s wee on your lawn or garden are similar to that of liquid nitrogen-rich fertilizer. A tiny controlled amount of fertilizer makes the grass healthy, but excessive amounts will kill your grass. To prevent the grass from burning, you need to reduce the nitrogen amount that comes into contact.

When proteins in your dog’s diet are digested and synthesized, they produce both ammonia and urea, two of the standard nitrogen compounds that must be expelled from the body. Depending on your dog’s genetics, diet, and environment, they may produce a bit more nitrogen compounds as compared to other dogs. High amounts of nitrogen can be hazardous for your yard, resulting in the dead yellow spots from your dog’s urine.

You may be wondering that nitrogen is the main component of lawn fertilizer, so why does my dog’s pee burn grass?

It does seem weird to say that the thing that is dangerous for your lawns is the same thing that you use to regrow it, but as with all other things, too much of anything can also be harmful.

In the proper amounts, nitrogen helps your grass grow healthy and robust, but extreme nitrogen levels from your dog’s urine, when concentrated into a small place, will burn the grass.

You might have noted that some of the tallest, healthiest grass is present around the edges of those dreaded yellow stains. That’s because the grass surrounding the yellow spots received the fertilizing benefit.

How to have a healthier lawn:

You can follow the tips listed below for a healthier and greener lawn:

  1. Fertilize your lawn less in the places where your dog urinates:

Fertilized lawns already have as much amount of nitrogen as they can handle. As it happens, a tiny amount of nitrogen in your dog’s urine may be all it needs to burn the lawn.

  1. Spray areas where your pup urinates with water:

 Pouring water on the particular area after your pup urinates on it will aid in diluting the urine and reduce the effects of nitrogen on your grass.

  1. Provide more water to your dog:

If your dog drinks more water and is constantly hydrated, there will be less nitrogen concentrated in the urine, and in turn, there will less damaging to your lawn. It is also healthier for your pup.

  1. Replant affected areas with urine-resistant grass: 

Plant Fescue and Ryegrass in your lawn since they are the most urine-resistant kind of grass. Try to avoid the Bermuda and Kentucky Bluegrass as they are the most sensitive type.

  1. Feed your dog dietary supplements:

Some dietary supplements bind with the nitrogen in your dog’s urine, making it less hazardous to your lawn and grass.

How to stop dog urine from killing grass naturally? 

If you want to protect your garden, then prevention is better than cure. Make sure the balance of your dog's diet is right and that he is not getting too much or too little nutrition.

Use dog rocks. Dog stones are made of natural stones and offer a 100 percent natural solution to dogs urinating on the grass.

Can you repair brown grass? 

According to gardeners, it is possible to recover the brown dots from dog urine.

Start the restoration process by watering the piece of ground. Do this for about a week. If after a week it has not recovered by watering, then you should replace the seeds. You do this by removing the seeds and replanting grass.
