Dog Spots

Get Rid of Lawn Dog Urine Spots

Oh no, you've got dog spots on your nice, lush, green lawn! Dogs don't seem to notice where they're doing their "business" when nature calls. They just answer the call!

Unfortunately, they leave brown spots on the lawn as a marker of their duty done. These dog urine spots cause too much concentrated nitrogen to be left in one spot.

When you think about it, the soil under a fertilized lawn contains good amounts of nitrogen. Urine spots simply add a little more nitrogen to one spot, which is enough to distress the turf in that area.

The Remedy

It's similar to spilling a bag of fertilizer on one area of the lawn. When that happens, the best remedy is to flush the spot heavily with water after removing as much of the fertilizer.

So too, with dog spots. Turn on the garden hose and flush the spot well if the "deed" has just happened. This works equally well within a few days of the dog urinating, helping to ward off damage to the lawn.

If the grass is already brown however, it's likely that the roots of the grass have been killed by the dog urine in that small area. In such a case, the only thing to do is to repair the grass.


You can replace it by taking a plug from the edge of your garden or some less noticeable place in your yard. Measure the damaged area and remove that portion only. Take it to the area where you're harvesting the plug from, lay it on the new grass and cut it to the proper size. Place the plug into the original damaged spot, and tamp down firmly with your foot.


Another option is to thoroughly rake out the dead grass, being sure to loosen up some of the soil. Sprinkle on a good covering of quality grass seed and gently rake it into the soil to cover the seed. Keep it consistently watered until new growth appears, and then water as necessary.

The Bottom Line

If you have a dog and a lawn, you're going to have dog spots. Dog owners, knowing how urine spots affect the grass, simply watch, water and replace as needed.


  • Female dog urine is not more potent than the urine of male dogs, as many think. However, it does cause more trouble, because females tend to urinate in one spot all at once.

  • Gypsum, which is really calcium sulfate, can correct certain levels of pH imbalances. Remember, dog urine leaves an over-concentration of nitrogen, and is not a pH issue. Gypsum is not going to help regrow the grass or make it come back green. It's not the best remedy for urine spots on the lawn.
